I suffer from tinnitus for about twelve years. At first I thought I was hearing fluorescent lighting, electrical devices, or that medication was making the sound (aspirin, acetaminophen, etc.). After telling my doctor about it, because it had become quite loud, they diagnosed tinnitus. I was amazed that no one else was hearing this constant tone. That it was coming from inside my head. It was explained that they believe the hearing loss I have has eliminated a tone or tones my ear no longer can hear, and my brain is "filling in" the tones it thinks should be there. Indiscriminately. Curiously, when I said sometimes it bothered me so much I wished I was deaf, the audiologist said that even deaf people can hear it. I asked a deaf friend if she had ever known of a deaf person with tinnitus, and she herself had it (things can always be worse). By the way, the sound on the sample you played is very close to the frequency of my tinnitus. Some have theorized that there are some therapeutic benefits to listening to the frequency or frequencies one hears on a regular basis to dampen the daily sound. Also many have said a specific diet or supplements or even meditation can resolve the problem. None of these have resolved this for me, however, it's still 24/7 constant whine in my head. I was also told I would eventually not notice it, and I am still waiting for that to happen. I don't know what is going on with the Havana Syndrome folks, but I can relate to some of the torment. Regardless of where it comes from, I have to say I will be mighty pissed off if it comes out that something man made caused this. Thank you for your analysis and for giving many scenarios as to what might be going on.
I get infrequent tinnitus. I usually never know the trigger but the most recent painful bout was caused by an antibiotic I've been taking. I'm even hearing some as I type this. I also 'hear' high pitched tones from some electronic devices while they're turned on. And I can personally attest that, even though the 'sounds' may be in the same frequency ranges, they are not the same. Having experienced both of these my whole life, I can tell when one is either internal or external. Also, crickets can sound very much like tinnitus, if there are enough of them chirping together. It can even feel similar as it reverberates through your skull. Locusts can be even worse.
I have tinnitus. I’ve had it for some years now. I don’t know when it started. One day you just notice that it’s there. I thought I was hearing water in the pipes. I used a tone generator to try to match what I hear. I got a reading of about 8.7 kHz.
Some other microwave sources in US embassies: 1. Use of satellite comms gear to link back to US (I worked for one of their providers). 2. Many embassies include NSA receiving equipment for monitoring local mobile phone networks and other radio comms, the use of countermeasures to reduce the collection efficiency by jamming is not unknown. 3. On-site communications using encrypted UHF radios.
Microwave radios are not powerful enough to have any effect on human neurology, unless you're standing in front of a radio station broadcast emitter that runs at tens of thousands of watts. Small microwave sources could only have any effect if they were focused, like masers.
None of these things are at the frequencies that could heat tissue. Why design a communication device with a signal that resonates with water?; it would be terrible. If it's microwaves, then it's malicious (or a series of very unlikely accidents).
@@V1ND1E: Actually the 2.4GHz band *can* heat liquid water, and was chosen for short-range consumer-grade communications (Wi-Fi, cellphones, RC cars, etc.) because humidity in the air makes it opaque to 2.4GHz microwaves over long dstances, so that band is useless for long-distance communication. (also because there is already a hopeless amount of radio noise in that band from microwave ovens.)
@@LostAnFound: Sources to cite for what? That 2.4GHz radio excites water molecules? It's (relatively) common knowledge; a quick Google search will get you plenty of sources. Also nearly everyone who has used 2.4GHz Wi-Fi has experienced having their internet speed crash when their microwave oven is running, and obviously microwave ovens would t use the 2.4GHz band if it weren't useful for heating water. There isn't enough radio leakage to cause harm, but there is enough to confuse sensitive electronics. The switch to 5GHz Wi-Fi (which was always used by professional grade Wi-Fi equipment) largely eliminates the problem of interference from microwave ovens. Interference from humidity is a non-issue in both bands though, because consumer-grade Wi-Fi doesn't have enough range to be affected by it.
My dad worked for the ADT company and installed ultrasonic devices in security facilities in the '80s and '90s. These were to disrupt "enemy" laser devices which could be focused on the exterior windows and listen to people inside the facility. The security devices were an adaptation of the normal ultrasonic motion detectors. We had some at our home and I could hear them. But, most people could not. So the problem could be self inflicted or the inside ultrasonics were being interfered with by exterior ultrasonics.
@@PhillipAmthor Possibly, Sabine said that two out of phase devices could cause this. What would be more out of phase than a US inside device and a non-US exterior device?
Hello Sabine, I’m not a scientist and my education is only at a high school level. However I admire your inquisitive mind and insightful point of view. Your video presentation is superior to most of what I see on RU-vid. And even though I struggle to grasp the concepts of your lectures I always come away with some precious piece of knowledge!😎🍀⭐️
Are you sure Frau Doktor that, the exactly same stupid sound that you present in your video was really recorded by Associated Press at a private home of a diplomat in Cuba? Who wrote that script for you, Frau Doktor, perhaps Hitchcock during a Psychographic session from the afterlife?
You sure touched a hot button with this episode! Last year I donated a device to the International Spy Museum in Washington DC that was powered by remote microwave beams and would re-broadcast local conversations in the VHF range. But as an old radar hand, I completely doubt the microwave explanation. Thanks for a very balanced analysis.
When my dad was in the Navy he was a flightdeck troubleshooter and plane captain for an electronic warfare squadron. One of the "pods" that was often attached to planes was, for all intents and purposes, a massive EM generator that put out so much power that it fry its own control circuits with the EM pulses it put out. If the pilot couldnt eject the pod before landing on the deck, they would have to turn off the majority of their electrical systems on the carrier to make sure nothing got permanently damaged and the troubleshooter was *supposed to* suit up in a specialty EM resistant suit that looked like an EOD bombsuit. During a wargames simulation, an EM pod fried itself and they needed to get that plane down and they system off as fast as possible. My dad, being young and dumb, didnt bother with the suit and just sprinted out and yanked the power cable as fast as he could. Immediately after pulled the cable, he puked his guts out and was sick for the next day with headaches, nausea, hearing shit that wasnt there, and all kinda of weird symptoms.
my ex-brother-in-law was a Navy Captain - I was able to get a family ride on the warship he Captained during a military festival for the public where they did some highspeed maneuvers and actually fired their main gun (totally insane) - he said they have certain systems they can't bring on-line unless they are 50 miles offshore because it would bring down all civilian communication along the coast - space is only 100miles up, they could easily be doing it from orbit if they wanted to
It was a piece of Navy equipment, heavily modified, we used on our trucks to disrupt remote detonated IED's. When we would wear the in-truck headphones, a necessity for communicating out of the turret, you'd get a sound just like that, but much lower volume, in the background. But only when we were running with the equipment turned on. Always wondered about that.
I remember that a cold war case was based on using microwaves for surveillance in an embassy. The embassy had been giving a bust of an eagle as a gift and, since it passed inspection, it was placed on the mantlepiece. But its secret was that it had been designed to be a microphone that modulated a signal from a maser passing through it. A maser being a radio frequency laser, creating the radio equivalent to laser light, ie single frequency, both spatially and temporally coherent and in a focusable beam (these are redundant qualities, but it makes it clearer what you can do with it). I guess it was the Russians, I don't remember - beaming radio waves through the embassy and picking them up on the other side so they could record conversations inside the embassy. But the beam was strong enough to harm people who got in its way.
It’s very real, extremely dangerous, it’s a weapon of mass destruction. We built it in the 1970’s but shelved it because it had zero accuracy, and would cause mass collateral damage. However, we are so embarrassed that our two biggest enemies have stolen this weapon and are now using it against us they not only refuse to say such a weapon exists, but actually say such a weapon can’t even be built. How could they know that a weapon couldn’t be built if they don’t know what the weapon is? It’s a high powered, high intensity sonic pulse weapon that makes zero sound, and can penetrate massive buildings from far distances and destroy human brain tissue physically and permanently. Insanely, this weapon was actually for sale in the 1980’s in the back of super nerdy tech magazines (that’s how I discovered it’s existence). The sixth highest ranking member of the CIA was a victim of this very real weapon, destroyed his life, yet despite his long 26 year distinguished career in the CIA, was refused permission to go to the hospital on three separate times despite the severity of his symptoms (something that’s never happened in his career). It got so bad he went to Walter Reed anyway, and with the hundred of other victims of this weapon, the doctors believed them and even started it’s own unit for these victims. This guy went on the Shawn Ryan show and was interviewed about it.
Very interesting video, Sabine! A lot of interesting stuff covered in it. Hadn't heard of the Frey effect. I had heard that brain changes had been found in the ones suffering from the Havana Syndrome, but hadn't seen anything with nearly as much detail as is found here, either. You rock, Sabine!
The sound recording is very similar to what I would sometimes hear around an ultrasonic device used to measure water levels in a flume at water treatment plants. The device was made by Fisher Porter Co which uses an ultrasonic transducer mounted inside a fiberglass horn to direct the energy. The noises I heard were produced inside a concrete pit and could only be heard in particular areas inside this pit. My conclusion was that the ultrasonic sounds from the transmitter were being bounced off the walls of the pit and at certain places within the pit, an interference pattern was being set up that resulted in sounds within the human hearing range.
Looks like you're describing standing waves. And it's perfectly reasonable. Also, it's not uncommon to have standing waves inside buildings. The shapes of the rooms lends itself to that.
From my understanding, standing waves are still the same frequency as the source. Also, the source put out a wave train lasting about 10 milliseconds, with around 10 trains per second which would sound like a clock ticking. Every few seconds the train rate would increase to around 50 per second. The pulses were used so that between each pulse, the transducer would listen for the return and use the return time to determine the distance of the target it reflected from (the water level), The increase in train rate was a self-calibration routine, where it picked up the reflection from a fixed target at the end of the horn. The noise I heard was nothing like those pulses and at a lower frequency. More like some sort of interference pattern. Also, it always sounded like the noise was being produced somewhere just in front of my face. It was very disorienting and disturbing.
@@Endymion4242 I'm not sure if that is true. You often generate harmonic with electrical signals. Would sound waves be any different? Fisher Porter included detailed manuals supporting those tranducers. I can't remember if the tone generated was the same frequency or not. I think the calibration routine used a lower frequency
You don't need to assume many incompetent spies for the ultrasound hypothesis at all. Multiple otherwise quite competent secret agencies trying to eavesdrop at the same time (without knowing or coordinating with each other) could lead to the same result as well. Given the position of the US in the international relations, it seems quite plausible to me.
Yes, if they happened at the same time, it could be whatever the newest spy tech was at the time causing this. Not crazy to think all the spies bought product from the same high tech company or something that works on the same principles and since it's new, it's more subtle side effects weren't yet apparent.
The video itself is a killer message. Anyone who had anything to do with the royal family also had to do with the KGB or the German family or the Rockefeller family. These guys and the secret services behind them have nothing to do with honor and justice, but are basically criminal organizations that are involved in human trafficking and the secret services should make sure that this is not noticed. I've had to throw up my creativity on the music industry and the children of David Rockefeller (Hollywood film industry) all my life. It started when I was very young. These criminals protect themselves in a variety of ways. One method was to put such a scratchy noise on my headphones and, after hours of torture, suggest to me that if I ever heard this sound, I would have a heart attack or cancer. I still remember how the Russians tied me to a table and drummed this crap into me. 20 years later I kept getting calls from alleged competitions, where a friendly lady with a Russian accent told me about great prizes that I never got, and in the background there was always this scratchy noise in the background, unlike the usual telephone interference. Now that I've seen this video, my heart beats again, just like the day I was immunized against whipped poison (was bitten by 5 baby najas and had to endure it.) My pulse goes up and down and I get dizzy. Any agent will recognize that, and maybe a few viewers die, maybe an hour, maybe two hours after watching this video.
Here is a VERY IMPORTANT & very little known quote by the person which discovered the microwave hearing *&* the skull vibration effect (which aren't the same thing) back during the advent of radar, Allan H. Frey, who posted this in 1996 on Usenet: "There is a microwave hearing effect that occurs at very low power densities and a skull vibration effect that occurs when very high energies are applied to the head. There is some confusion in the literature because the vibration effect has often been referred to as a microwave hearing effect, but it is not the same phenomena." 99.9% of literature on this fails to account for this distinction, most shameful of all the, albeit not quite traditional literature, Mythbusters episode on the subject
I swear, most of the time I hear about something Mythbusters did, it involves them unintentionally spreading misinformation about something they were supposed to be "busting." Always "one myth busted, two myths created" with those guys.
Also Sabine in case you read this it seems an archive link I posted here which contains a LARGE academic bibliography got stuck in the spam filter please could you maybe unstick it?
I really like how you are so careful not to overstate what you know. Sometimes you speculate, but you are very clear to say that. it is very rare to hear people speak so Sometimes you speculate, but you are very clear to say that. it is very rare to hear people speak so Clearly and honestly.
I can "Hear" and "See" the frequency of All Florescent Lights and I can't stand it! or work indoors! As a young boy the day I got Braces on my teeth(1977ish) I could "HEAR" Radar? or Radio? at a local SAC AFB it drove me crazy, High Pitched Whine dead inside my head just like the sound "you played", Parents did not believe me, but I proved it to "myself" as I got closer it got worse. I described "my sound" as what I would hear when I had a fishing hook and line stretched tight on a fishing pole's eyes and the wind blows causing the taught string to "sing", very low volume, very high frequency or pitch, or like some high speed boat props sound from far away when your ears are under the same body of water. No one else in my family had this problem. Mom can only SEE the frequency of fluorescent lighting.
My deepest congratulations to you Sabine for your nice message to the patrons. This did seem to me a very balanced message where initially you thank all the patrons equally and then you thank especially the tier 4 patrons, which I think is an excellent gesture on your part.
I have heard that sound myself! It is from ultrasonic transducers used in various pieces of scientific equipment. The more powerful instruments can actually drive a person from the area. Not because it is loud but very uncomfortable to be around. Also, it is impossible to determine the direction it is coming from. The power supplies for the transducers are not very big. The one I used was about as big as a toaster oven. I’m sure they can be made directional. They may be capable of remote sensing of vibrations such as speech on walls or windows. Who knows. Just speculation on my part.
i dont know what a “transducer” is, but, um…. let’s assume for a moment that an ultrasonic transducer is indeed the source of the havana syndrome….. why would an ultrasonic transducer end up in (or near) a U.S. embassy, do you think???
@@AuntBibby The transducer (sometimes called a horn) is not very big. The one I have experience with was the size of a one foot long piece of 1 1/2” pipe. You could easily carry it around. The challenge to me would be to make it directional.
@@AuntBibby Many things are generically known as a 'transducer'.... A microphone, for example, is a transducer .. so is a speaker .. so is the cartridge on a record player .. so is the human eardrum and etc.. As for why some form of sophisticated 'transducer' may end up near a National Embassy; Spy games is the simple answer.
RF (including microwaves) and sound can be used to energise bugs which then report on a different frequency or channel. This can be direct to power or trickle charge. In the past these bugged devices have been part of gifts (murals), furniture or built into walls. The human health issue may have been an unfortunate and unexpected side effect.
One of these things - literally "The Thing" made quite some waves in its time. I assume that counterintelligence has investigated this and thorougly scanned the RF spectrum at the embassies and searched everything there for devices like that. The results of these investigations might be classified though. en.wikipedia.org/wiki/The_Thing_(listening_device)
I suffer a psychosomatic reaction to a few triggers that cause me to gag. I know it's 'all in my head' I'm acutely aware that my reaction has nothing to do with anything physically wrong - yet the symptoms, which are very real, persist none the less. I think we have to careful in equating psychosomatic with imagined.
Microwaves and ultrasound waves are very easy to detect. I would imagine that they have such sensors in embassies already. I think it wouldn't be too difficult to make a wrist watch that could tell, if not in high detail, but easily if abnormal microwaves or ultrasound is present.
@@2adamast Spying equipment and weapons for agents come through the embassy, all major powers do that with even friendly nations. But they're not used in the embassy, they have cocktail parties there and try to help their compatriot tourists who have had a little too much cocktails and lost their passports or got in trouble with the law.
@@atklm1 This is true. You'd think they'd be considered concealed wireless life support health aids... though some of course can use invalidly as weapons that are concealed wireless assault weapons operated from remote sensing stations. Therefore, you get a sound, body and mind control assault weapon.
How would they tell the difference between the emission from foreign and internal spying? I dont think the US government would be too happy about the subject wearing a watch that detected spy equipment from internal affairs.
I'd like to add my personal experience with related phenomenon. Decades ago I had a neighbor who would play OBNOXIOUSLY loud music at middle of the night parties during work nights. It was the kind of volume that said we DGAF about anybody, so there was little point in complaining. As an electrical engineer at the time, and also having significant passive aggressive tendencies, I set out to build an ultrasonic sound system to invoke "behavioral modification". That is, to project a directed audio beam into their backyard with controllable frequency (from the ear piercing high frequency end all the way to the ultrasonic range) and adjustable power level. The idea was when they played their music loud I would turn on what I came to call the "Sonic Disruptor" to painful levels. They would experience headaches and would turn down the music. I would accordingly turn down my Sonic Disruptor. In this way I proposed to modify their behavior covertly so as to produce more peaceable results in the neighborhood. The system I built consisted of a control box with a long cable going out my bedroom to a tree in my backyard and intercepting a shotgun plexiglass asembly with two high powered tweeters within. That way I could hang that assembly in the tree and being mostly transparent would not be noticed. I took the thing to work to demonstrate to my coworkers and they all said to turn it off, either in the hearable range or in the ultrasonic range where it created pressure in the ear without sound thereby causing confusion and discomfort. The irony is that by the time I was ready to install it and put it to use -- THE OFFENDING NEIGHBORS MOVED OUT!! So I never got a chance to use it in "combat" so to speak. Anyway, when I heard this story when it first broke that's what came to mind. Someone is playing psychological games with people using near ultrasonic audio.
@@erinm9445 "It was the kind of volume that said we DGAF about anybody, so there was little point in complaining." My life experience has been that if someone is jerking you around with a case of the IDGAF's, if you make yourself known to them on the pushback, you make yourself a target since it's already clear they're an ahole. So if you *can*, better to do things on the down low. That's 50+ years of life experience on Shole Planet.
That sound simply reminds me of my own tinnitus, and I'm pretty sure I wasn't targeted by any spy 😋 My only interest in this is it may help us identify sources that can cause tinnitus, it's sometimes really difficult to live with those.
Me too! I immediately recognized that sound. It's what I hear all the time, inside my head. A complex of pitches with varying amplitude around 7 to 9 KHz. No one has been able to tell me why those pitches and not others. My suspicion is swelling around the eustachian tube putting pressure on the auditory nerve. My only way to deal with it is to consider it my own personal drone, and live with it. Otherwise, it would drive me crazy.
I am a victim of the Havana Syndrome weapon from 2005. It left me permanently deaf in my left ear, and left me bedridden with uncontrollable vomiting for over a year. I know what the weapon is, I found out about it in a magazine in the 1980’s. It’s a high powered, high intensity sonic pulse weapon. DARPA built it for the CIA at their request. They shelved it because it had no accuracy and would have enormous collateral damage. It’s so powerful it can penetrate reinforced concrete office buildings from far away. It makes no sound, unlike this video states, and you don’t realize your being attacked with it until it’s over, destroying your brain (severity depends on length of exposure). It’s a evil weapon of mass destruction. And the CIA is so embarrassed that our enemies stole it and is using it against us they refuse to admit it. There’s no Known defense against it, it’s scary. It’s so bad I would have rather have been shot with a gun.
Tinnitus is kind of a clinical enigma, and yet it has the potential to be absolutely horrific. They need to fund more research on curing it or at least treating it.
I've got a pulsating cricket like thing just in my right ear too. I discovered this after getting my ears cleaned of wax and got the tested too which indicated right ear hearing loss. Luckily it's not bothering me.
The recording she plays, is exactly the sound I have been hearing in my right ear for more than forty years. It is about a 5kHz sine wave. It is much louder in my ear than the speakers on my PC. I will know I am dead, when that sound finally stops!
@@deanwright7611 I've had the pulsating crickets. That one I don't even mind. The electrical sounds and ringing is the worst though. Volume is also a factor.
There is not just one cause for tinnitus and that is why it is so difficult to treat/cure it. It is easier to endure if you consider that sound as an "invisible sometimes loud friend"😉
For a narrative about the difficulty of finding the cause of an effect, I recommend the novel "The Investigation" by Stanislaw Lem. This starts as a weird police matter and escalates into something altogether else.
Thanks for the book recommendation! I read one of Stanislaw Lem's books years ago on someone's recommendation, liked it (as I recall), then forgot about him. I'll no-doubt re-discover him now.
If only there were some sort of technology that could analyse the microwave (and THz) RF spectrum, and display it on a screen. It could be called, I don't know, maybe a "Spectrum Analyzer". Then, with the use of an obscure technology known as a parabolic reflector, they could somehow get a bearing to the source. Let's call that "Direction Finding". Then, using an image capturing technique, let's call it "Photography", they could somehow capture all this info and 'Save As' a PDF file, to be made public to humiliate the enemy and eliminate the mystery. If only any of this were possible... For ultrasound, use a suitable directional microphone. Sometimes the absence of evidence is actually very interesting. Not sure why, but it's weird...
Yah, most of these "mysteries" are only mysteries to the non technical. I heard about this long ago. They have been sweeping for these kind of bugs for decades but the general public is blissfully unaware.
Of course if it is a sporadic thing directly pointed in one or a couple people's direction, why would anything be picked up when it's not pointed at anything?
I've lived in high rises and in a basement apartment in a high rise, and I swear the vibrations of the building would make me feel nauseas or just plain bad sometimes. Just this constant sound, and then it would change, but so distant. Makes me wonder how hard life must be for animals in zoos or cities with good hearing, or dolphins and whales that have to deal with ships all the time.
I can tell you that sound is exactly like when you blow into a piezo tweeter that is producing 'near ultrasound' (15,625kHz in my case). Comes from when I built a 'squawk box'; something that was experimented with as a crowd control device by the military; it generates two sources of high pitched sound, and the beat frequency is what is meant to disturb you. It definitely works to some degree - can't tell whether it has been switched off for around 10 minutes, also good to make rowdy drunks quiet - it's not even that loud. Most modern devices use a switched mode power supply that can also generate near ultrasonic sounds - maybe that is a cause of some of the reports.
I can hear it at the current house I live in. It sounds like a large fan running or like a B-17 bomber flying in the distance. It's really windy where I live so I think it's just the wind blowing across the chimney or vent pipe like blowing on a coke bottle. It's definitely a real noise because it's louder in some rooms than others and it goes away when I go outside.
Some of the locations where the "hum" has been heard have been solved. In one case, a guy was bothered by it and made it his mission in life to figure it out, and he found out it was coming from air conditioning units at a recently built big server farm building. That solved it for that location, but other places, including Taos, are still unsolved apparently.
Spying is interesting. In Sweden we had issues with sounds under water that sounds like a submarine. Our navy gathered marine life scientists and they said it was herring farts. That earned them a ignoble prize. And in the end we had a Whiskey on the rocks :)
@Sabine : thank you for a video presentation that captivated my attention from beginning to end. I immediately thought about "tinnitus", and when you mentioned ( I guess "pulse amplitude modulation") microwaves: I recalled evidence of such signals being "detected" (i.e. converted into audio frequency signals) by dental amalgam fillings and creating audible sounds that were conveyed through the mandible (lower jaw-bone) to the cochlear, and thence to the auditory apparatus in the brain, thus causing a sensation of perceived audio sounds which were capable of being recognised as spoken words or music. Sorry - I can't remember the source of the information that I recall.
@Jim: thank you for this information. I suffer from a low frequency tinnitus on the left side, around 235 Hz. For a long time I mistook it to be caused by ventilation equipment or a transformer somewhere in the apartment building where I live. Only recently it occurred to me that the tinnitus started after a dental treatment but I couldn't think of a possible explanation. I wil soon be seeing a doctor for this problem and take this with me.
I have a lot of lower fillings, they are the old metal kind. Is this what you are referring to? If so, I wonder if it could be causing mine? I will ask the dentist next time I go. Wouldn't that be great if it was, and I could just replace them with something non-conductive? Thanks for sharing this!
@@d-star491 unfortunally no, that doesn't seem to be the cause of my tinnitus. Recently I read about possible influence on tinnitus from divergent levels of dopamine and serotonine, hope to find out more about that the coming weeks.
I am in Hyderabad, India. I have noticed this sound ringing in my ears for about last 2 months, i.e., since September, 2021. It was inexplicable. I was also having disturbed sleep. I searched internet for this and learnt about Havana Syndrome. I told my uncle. He told me that I was using in-ear ear phones for long durations and should reduce it. For the last 10 days, I completely stopped using them. Now the duration of these sounds I hear has reduced. I hear it for about an hour immediately after waking up from sleep. Position is improving gradually.
faulty air-conditioning? there was an old story where everyone in a building got really sick after getting inside. when the air conditioning system got replaced, everyone's back to normal.
@@adrianjanssens7116 Same thought ^^. Though it was not really faulty but at the time they didn't know about these bacteria and that the humid conditions on the outside heat exchanger was the perfect fertile ground for them. It's actually a quite interesting story how they found the bacteria first and also actual source were it came from: en.wikipedia.org/wiki/1976_Philadelphia_Legionnaires%27_disease_outbreak There was a Forensic Files / Medical Detectives episode about it. It was the 7th episode of season1: en.wikipedia.org/wiki/Forensic_Files_(season_1)
It could be that crickets in the area were excited by the same energy source. Or the recording of crickets in one instance could be a case of false correlation, ie coincidence.
Not so sure this is what she was saying. It was only suggested that the one external recording of sound captured may well have been Crickets. It was not supposed as a general blanket explanation at all and to all reported cases of the phenomena. It appears most of the cases of auditory 'hallucination' are likely inside the head.. and not perhaps something that may be externally recorded at all.. OR; perhaps just more recordings need be produced/come to light.. in order to help rule out mere 'mass hysteria' effect coupled to conspiracy theory.
Regarding crickets. My father is growing old and one evening I asked if he could hear the crickets but he could not. One cricket was close by and unusually loud so I pointed to where it was and he leaned over to listen and suddenly he could hear it. Some time later he said that it was slightly annoying that the crickets were so loud all day and all night. I was a bit puzzled because the crickets had already gone silent. It took several more weeks before the sound stopped echoing in his head.
similar kind of health problems could be caused by all electrical equipment. For example, I bought a router some 15 years ago, and then forgot about it sitting idly on the corner. 5 years after that I found out odd symptoms, and eventually it was traced to the router's charger that was broken, i.e. the equipment was just broken. The problem was that it was very difficult to figure out what was causing the symptoms. Unplugging the router from the electricity mains magically fixed the issue though. That equipment went to trashcan faster than I have seen anything move in my life.
My uncle had similar syndromes decades into his job as an air traffic controller. Turns out immense stress and the psychological impact of the job was too much. I imagine a position that includes similar working condition on top of the nature of the things they work with (shady shit, torture, dead civilians and the like) takes a massive toll on mental health in prior neurologically healthy people
I've got to admit, I'm kinda proud of myself for already being familiar with statistical significance and analysis of variance going into this video. Really cool to see it brought up in an entertaining yet substantive manner.
Back when I was working as a chemist I used to clean glass substrates using a small ultrasound bath. That sound she played sounds just like that small ultrasound device.
Publishing for clients that aren't popular has led to extremes of human behavior that, at times, I’ve needed to take leave of just to get rest. Most recently, I’ve been able to get one or two nights of rest without disruption or interference depending on how quickly and quietly I depart, but the noise usually returns within a day or two regardless of how I’ve departed either because I've been discovered again, or found to be disturbing on my own. I believe it's safer to stay home and work on negotiation than it is to risk hazards at large, but the noise I live with at night can become painful, and I have no choice but to get up and wait for it to abate which is very tiresome, but a daily fact of my life.
I have higher auditory range than average humans ( up to nearly 19 KHz) . I can tell you from personal experience that some fire alarms (they use ultrasound to scan for smoke) are deafeningly loud, yet everyone is oblivious to them. When they installed new fire alarms in Stansted Airport I noticed as soon as I exited the plane, and by the time I managed to leave the airport I was ready to throw up. Luckily, ultrasound gets blocked by solid objects, so simple headphones negate most of the volume.
I used to be able to. Once I passed 50 yo, my high end began to dim. Now, I'm lucky if I can hear 15k unless it's super loud. The world sounds a little dark or muted compared to what I used to perceive.
I bought a ultrasonic animal scarer for the garden, as my vegetable beds were being regularly dug up. I was in my early 60s at the time, and could hear nothing from it - I was never sure if it was on or not. But my kids, then 9 and 5 hated the thing and wouldn't go near it, they said it made a painful high-pitched "hissing noise". In the end, I had to stop using it, as it was clearly distressing them. Cats, squirrels, foxes, etc of course just ignored it! My youngest also wouldn't go near public toilets because he said the hand dryers hurt his ears.
@@paulhaynes8045 Yeah, those Dyson Airblades are an absolute nightmare for some people, myself included. Also a good many carriages on the trains where I live have some sort of electrical interference causing loud, high-pitched tones to be emitted by the announcement system, but most of my friends and family, with the exception of the autistic ones, are totally oblivious/unphased.
Sabine, the fact that the cases were reported independently doesn't rule out mass hysteria. Also, those neurological alterations could still be correlated to mass hysteria inasmuch as they could be necessary for the development of that kind of psychosomatic disease.
I am working in a 3 storey house in a quite narrow street opposite to a 5 storey building. Both facades are rather hard with very little structure. The distance between this facades is about 25m. Some 50m away is a traffic light. During the day it happens regularily, that a public bus is stopped by the traffic light just in front of the house, and its big diesel engine gets into idle and stays so until the traffic light shows green again. Usually this situation lasts about half a minute. Then everything seems to get into resonance at a subsonic frequency, the whole room seems to vibrate, but you can't hear anything, instead your ears seem to close up, so other noises seem to be subdued. Simultanously a certain sickness comparably to sea sickness starts within your belly. Just before you are seriously incapacitated, the traffic light changes, the bus driver gasses his engine, and all effects vanish immediately. I case this would last longer it could be that Havana syndrome.
In my youth I belonged to a group which conducted experiments in the RF portion of the electromagnetic spectrum. One fellow was blind- no light perception. Already he was trying to couple his occipital cortex to a TV camera to restore his vision. We tried for the human audio spectrum first. We fitted a multiturn coil around his head and impedance matched it to a 30 W amplitude 40 M transmitter. We put him in a distant room and read a sentence into the microphone. He recited the sentence perfectly. He remarked that the audio was clear. I have no doubt that microwaves could be the part of the spectrum used in Cuba.
I remember reading, sometime in the 80s (I can't find a reference to the article, unfortunately), about a microwave technique for listening to people speaking in rooms with windows. The article explained that voices in a room cause its window glass to vibrate. If a microwave beam is focused on the window pane, the pane's vibrations cause the reflected microwaves to be frequency modulated (via Doppler effect) and a receiver can be used to pick up the voices inside the room. Since most of the microwaves pass through the glass, a reasonably strong microwave beam has to be used to get the strength of the small amount of reflected ones strong enough so that a sensitive receiver can detect them. This would certainly provide a reason for why this was being done. p. s. I wonder, if the data could be obtained, how many of those people spent time in offices with windows. p. p. s. Though this was in the 80s, I suspect nowadays they would use infrared lasers as they're much harder to detect than microwaves.
You mean a en.wikipedia.org/wiki/Laser_microphone. Using microwaves for the same purpose would only work if you would direct it at an RF reflecting surface which vibrates with the sound in the room to be eavesdropped. However, microwaves can penetrate walls (unless they are shielded - which I would expect for an embassy, especially in a hostile country) and maybe the laser microphone principle could be used on metallic surfaces inside the building, e.g. filing cabinets made from sheet metal. But I am pretty sure that these possibilities have been investigated by counterintelligence.
@@KlausKaiserDB3TK I bet almost everything has been investigated by counterintelligence, they were doing the microwave thing before the 80s (probably 50s). Because of impurities, window glass does reflect a tiny percent of the microwave radiation; that's why the beam strength had to be powerful. That most of the RF radiation went through is why the people in the room would be subjected to a high dose of it.
The spectrograph of the Havana signal shows a carrier at 7.2khz that looks like it's being frequency modulated with 200hz at a high modulation index. You could build something that does this using two NE555 multivibrator IC's costing about a dollar total. and a speaker (or a tweeter for maximum effect). Definitely is an annoying sound.
That strikes close to home for me though I just realized it. I found that sound to be mildly irritating and I certainly wouldn't want to keep hearing it over time. That coupled with the fact that I have always hated the sound of crickets and had difficulty sleeping when they chirped all night. On the other hand I find the sound of large numbers of cicadas to be somewhat hypnotic. I also remember a story out of California where an entire town was suffering from some auditory effects that they thought were manmade but turned out to be some form of fish or mud dauber that was emitting a mating call by the thousands.
The IEEE subcommittee that recommends exposure limits to the FCC, generally recognizes only heating effects from significantly high intensities of RF. However, they do acknowledge that microwave hearing is "an established effect" of RF. They trivialize it as "merely an annoyance", and not a health effect. I wonder what people with tinnitus would say. It can definitely affect one's ability to hear, but impaired hearing does not seem to arouse the amount of concern that impaired vision does. But it should.
It would be very easy to detect high power microwaves with a spectrum analyzer and suite of wideband antennas (that I could supply 😁). You'd also need an attenuator not to damage the spectrum analyzer front end if there was indeed a microwave attack or jamming in progress. In fact I could provide this as a service to any concerned "diplomats". 😉
I just used an RTL-SDR... wrote the How to Make a Directed Energy Weapons Detection System for Less than $50 also so others can try to disclose. Guessing we're all under remote neural monitoring (RNM) with mass mind control to prevent disclosure unless controlled and agreed on. I mean... dude... handlers are a well known role with responsibilities to spy, deter and control their group they're assigned to monitor.
@@makuru.42 Not being able to have the Right to Repair or even access all the functions on not only the phone, other wireless devices for spectrum analysis is something I'd be alarmed at regarding a legitimate conspiracy to compound and conceal crimes as well as evidence in some sort of mass obstruction of justice scheme by malicious assault and battery masked armed robbers that maim, murder and not justifiable serial kill... since they're always in the commission of a crime and imminent threats where deadly force is authorized to be use.
Dr Robert Bartholomew was recently on the Mythvision channel discussing this same topic and has a book in which he attributes Havana Syndrome to Mass Psychogenic Illness. He makes a very compelling case IMO.
I think the real answer is likely all of the above. Perhaps some real ultrasound or microwave attacks occurred, meanwhile increasing media attention has led to more psychogenic symptoms. But whatever the truth is, I’m gonna guess that our CIA already knows.
7:50 Interesting. I've always had the "ability" to tell if a TV or radio was turned on in a room, even when muted or not immediately visible to me. It's not "hearing" in the same sense as normal sound, but that's the closest I can come to describing it. It's almost like "feeling" it my head, but then not like actual touch sensation either.
A physicist usually is not involved in the intricacies of the Central Nervous System as much as a Neurologist is. But the matter of possible adverse effects of electromagnetic interference with nerve conduction has not been studied. We tend to minimize the importance of certain environmental hazards when it hasn't adversely affected us. Remember "Acid Rain" the reason for dead fish in lakes and ponds in Midwest States? Later attributed to Burning Coal in Illinois and Indiana Chimney stacks? Read, "SILENT SPRING" a book that whose author looked into this matter of fish dying in Indiana and OHIO lakes. Governments usually don't ask scientists to stand by when governments are "practicing" a new weapon system on their own people. On this particular issue of experimentation, I would like to direct you to the military's experimentation of LSD as a hallucinogen that caused the immediate death of several individuals by suicidal jumping attempts out of several Hotel rooms in NYC in the late 50's. Government later admitted to having experimented the effect of hallucinogens. Please look these up yourself. I did when I was a Psychiatry resident in the early 70's.
The simple answer is that it’s 5th and 8th harmonics induced into the electric grid of the buildings due to solid state AC to DC power converters used to power Western electronics (110v 60 hz AC to 20v DC) on an Eastern power grid (50 hz). This will cause electric motors to randomly spin in reverse, such as the motors turning the air handling fans. When these fans spin is reverse, they produce both high frequency noise in the audible range (like the recording) and ultra low frequencies below audible range. Ultra low frequency sound can cause nausea, dizziness, headaches, visual hallucinations, and paranoia. An example of this is the Denver International Airport, which when first opened made many people think it was haunted due to the conveyors randomly running in reverse, people experiencing nausea, dizziness, headaches, hallucinations, and paranoia. The problem was found to be improper grounding and a lack of line filters on the power grid, which cause harmonic feedback on the electrical lines. The 5th and 8th harmonics act like a standing wave, which can cause electric motors to spin in reverse (conveyors and air handling fans), which in turn cause ultra low frequency sound. This is something an electronics engineer should have figured out quickly, if one was to be consulted. I was made aware of this phenomenon while training as an electronics technician in the military, and was fully aware of the problem at the Denver Airport while I was getting an electronics engineering degree. As soon as I heard about the Havana Syndrome, it didn’t take much to confirm that the US Embassy in Havana was running off the local power grid and had a locally manufactured air handling system. With all of they modern western electronics requiring AC to DC converters, and no one apparently consulting an engineer of grounding and filtering needs, it’s very likely that electrical feedback on grid caused the health problems reported. Thankfully, modern power converters include these filters, as it’s a know problem.
At the time of the Gary Powers incident, the US showed the UN a passive bug they had found in the embassy in Moscow which worked when an external radio or microwave signal was directed at it.
I sampled the recorded sound on this video on my spectrum analyser. The frequency is centred close to 7KHz and has sidebands down to about 6.2kHz and up to 7.8 kHz. There are about 8 sidelobes with time-varying intensities.
If the AP recorded sound is related to the syndrome (as opposed to just being a cricket) it does not fit the microwave theory. The mechanism in the brain as described would not affect a microphone.
Sabine, du machst Physik auch für Dummies wie mich spannend und man lernt sehr viel, was man sonst nie im normalen Leben lesen oder gar zum lesen finden würde. Danke
Patient: It hurts when I touch it. Doctor: Don't touch it. Patient: It hurts when I press here, it hurts when I press, there, and it hurts when I press over there. Doctor: You have a broken finger.
We know that adversaries are developing ‘psychotropic’ weapons. I mean, this little grey computer in our heads is almost certainly more vulnerable to concentrated energy/interference than we hope. The good news is wifi telepathy in some sense might be possible. The bad news is wifi telepathy might be possible
One thing I have thought of in addition to what you state is the use of magnetic loop antennas for the microwaves. These are compact and more easily hidden. The physics is that the electrical signal from the amplifier feeds an inductive loop instead of a more traditional antenna. That creates an oscillating magnetic field which in turn creates an oscillating electrical field and thus the radiation out. They are also very directional. In addition to permanent magnets and fancy circuits, this type of antenna is at the heart of an MRI scanner too. At higher frequencies and power levels, people do report strange clicking sounds when diagnostically examined.
In the 60's was a similar case, after the "Reader's digest" magazine: they "explained" a focused on embasy windows detected the glass vibration for trasducing the dialogues at the embasy of USA un the USSR. So these stories are so old...
When I was a young man, I could go into any house and instantly know if a television was on anywhere in that house. This is back in the day of televisions using a.m. for sound and FM for the video. I recall thinking at the time that it was from the CRT. To my young and acute ears it sounded similar to the recorded sound in your demonstration. The difference is that it didn’t pulsate. It was a single tone. Very very high pitched. No one else that I knew in my family or in my circle of acquaintances could hear this Tone. It was unsettling to hear something similar again here in my old age.
One problem with the "differences" study is that if you look at enough variables that describe two groups, your bound to find some with low P values just by random chance.
@UCZ37D6GtH3sJX6myRycwGfQ I think you have missed the point. In this case the study reads as if the group kept looking at different parameters until they got some with relevant P- values. They start with some broad brush parameters, which show nothing and then keep slicing and dicing the analysis until they come up with something “significant” without any a priori model of what they were looking for. It reads like a student project where they got a big fat null on the main measure and are desperately looking for something significant in the data because they are scared of presenting a null result.
It sound like "disfunctionate" transformators in cables for printers or laptops. My laptop does emit such a sound in an extremly quite way but annoying if I don't do louder aktivities like gaming. Or tinnitus if it is truly not locateble. Also permanent noise and stress in general causes sickness and tinnitus.
Fascinating and bizarre. The video game Control incorporated this event but in game world it was lethal and caused by a paranormally altered cowboy boot. I'm wondering if infrasound could have something to do with this, along with the microwave and ultrasound phenomena. (Also, the sound of crickets is what I imagine after some of my jokes don't work...)
Infrasound is different than ultrasound. Infrasound is lower than human hearing, 20 Hz or lower. Earthquakes are at shaking frequencies below the range of of audible sound. Although earthquakes can obvious cause objects to create audible sounds through retransmission, fracturing and falling objects. Very strong infrasound cause humans to vomit.
@@edwardlulofs444 Infrasound can also cause visual aberrations and has been mistaken for ghost/paranormal activity and can cause dizziness, nausea and tiredness. Since I found out about the ghost thing I've wondered how many strange experiences have such an explanation.
That sound is exactly the sound of my left ear tinnitus, I’m not kidding. Now I have something to compare it to, it is difficult to explain to my doctor.
While this doesn't explain people in the same places having the same symptoms but I have Meniere's Disease and I have all the same symptoms. That tinnitus sound is spot on. Vestibular migraines also have similar symptoms and stress and loads of environmental factors can trigger them.
To me it sounds like tinnitus, which I suffer from. That, and a massiv ear pain to go with it. Nothing can be done, and the strong medication doesn't help much. Never heard of the Havana Syndrome. Until now. Interesting.
Tinnitus is just one part of it. With chronic (lasting) tinnitus, you generally don't get the other side effects (headaches, nausea etc.) unless you have physical damage.
The first time I encountered ultrasound was when I was about 5 years old (late 1960s). We went to a local restaurant and as soon as I entered I could just barely hear something, but it felt like a pressure on my head. I insisted that it was a real thing. My dad talked with the manager and we found that they had recently installed a new security system which used ultrasonic motion detectors. They couldn't hear it at all. I turns out I'm sensitive to higher frequencies. My ears are still ringing from you sample sound at the beginning of your video. -- Yikes! You did it again!
There was some controversy when shops in the UK were installing high frequency noise machines to deter young people from loitering. Older customers could not hear the noise because of natural high frequency hearing loss that comes with age, but it made the young uncomfortable. But this wouldn’t explain why middle-aged spies and diplomats were affected.
Great Video Sabine! As I began watching it I told myself if there is no mention of Frey I would have a fit, but you did great and I thank you for showing the new Springer book by Lin, it will look great on my shelf next to all the Frey, Adey, Persinger, Binhi et. al. I had to buy three copies of Copson's Informational Bioelectromagnetics b/c they were so poorly made and the non-ionizing chapter keeps falling apart on me LOL, also I lost the first insert and decades later had to get another, but at least this time I had it laminated. Anyway, although just prior to the pandemic my research took a rather strange turn I have spent more than 20 years studying bioelectromagnetics. Some of the effects I have designed in the past might shock(haha) you. As far as the "Havana Effect" is concerned here are some things you should consider: Neural tissue contains trace amounts of magnetite nanoparticles, even single domain(100nm) The dural membranes encasing the brain can cavitate as can the fluid filled ventricles The skull is of course a cavity, and thus resonant, but more importantly Bone Is Piezoelectric Cybernetic interaction can overcome any amount of complexity What this means is a comparatively small power density can by way of what I call a "cybernetic cascade" cause a profound effect. The scans show a grid pattern of damage indicative of wave summation, but It is my opinion that this damage is largely generated by the subject(victim) themselves. A very carefully crafted signal initiates a process within the head system so to speak. Imagine striking a bell in such a way that it "rings itself" long after it would normally have quieted down. So to my mind it would be incorrect to label this effect as either electromagnetic waves or sound because in a sense it is both. Also I believe that this technology is not new, so its re-emergence may be due to a novel delivery system.
Got my copy of the 2021 Lin today! It is Awesome! An entire chapter titled "Thermoelastic Pressure Waves in Canonical Head Models", HUZZAH! So as I was elucidating rather clumsily, just add coupling and piezoelectricity and Voila! Thanks again Sabine!
So when you talk the sound waves hit glass and cause glass to vibrate too. If you use a laser or microwave and the glass is of a specific composition you can measure the time it takes for the microwave/laser light to return to a receiver after being reflected off the glass. You can then take the those measurement to know the frequency the glass is vibrating and deduct the frequencies/amplitude of sound waves in the room. It’s a long distance way to hear without actually hearing
In the neurological study you mention you say there was a control group of people of the same age, gender etc. However shouldn't a good control group also be people of the same profession? It occurs to me that the people in question might as part of their job or inclination spend rather a lot of time on gun ranges, and potentially suffer ear damage as a result? The p values are very high, but what confidence you can have in them does very much depend on the quality of that control group.
I think the most likely explanation is a kind of mass hysteria, but not in the sense of psychosomatic symptoms. Stress does surprising things to the brain and the body. It’s incredibly natural that these people, with some of the most stressful jobs in the world, would experience any number of symptoms with no clear physical explanation. Once the seed of the idea of “havana syndrome” from some sort of direct energy weapon controlled by our nation’s enemies took hold, of course people experiencing unexplained symptoms began to use it as an explanation for what they are experiencing. Especially in a context where “mental weakness” would be regarded as shameful. The study that compared the brain structures of these diplomats and CIA agents with demographically similar controls probably used a control group of ordinary US citizens with incomes comparable to diplomats and CIA field agents. I can see why there could be a discrepancy in the toll stress may have taken on their brains. I’d be interested to see what conclusions are drawn by observing the brains of people with similarly stressful careers, or people who live in constant poverty.
Too many of these cases, with real damage, to be mass hysteria. You can't hallucinate that kind of damage into your brain without some kind of external assistance. Yes, they should compare the brains of diplomats and CIA agents before and after the onset of Havana Syndrome -- if they haven't done this already -- but I highly doubt that the results will be any different (except that you _might_ find some kind of damage that accumulates over time and then reaches a critical threshold to cause symptoms, but even that is unlikely to be mass hysteria). We had plenty of anti-Communist hysteria in the Twentieth Century, yet such cases were very rare.
@@ThePowerLover I can do no better than present an actual example of mass hysteria to explain itself: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4b-dannQQ0Q.html
It sounds like my tinnitus (but shifted up a couple of octaves and louder) and my tinnitus has increased, temporarily, after hearing it on my headphones. I have no hypotheses, but that sound rattles my molars and hurts my head.
12:30 AM 11/23/2021 I had similar symptoms at 16. I was working in a large New Orleans Restaraunt. Started as a dishwasher, up to daytime cleanup, to broiler assistant. Then I noticed a heavy vibrating hum through the floor. Made me dizzy, and nauseous. Had to decline working the broiler. It was the vibration of the air conditioner conducting through the beams of the floor, and up my bones to my ear. Unknown to me at the time I was later diagnosed with some minor structural problems with my ears. Made them subject to irritation, and low frequency sonic sensitivity. That sound is like a bad air conditioner bearing.
1.As a FM Synthesizer aficionado the those sounds are some harmonic dirts that occur if you don’t filter high frequencies enough ( aliasing, and other unwanted intermodulations.) 2. it was an ASMR (Autonomous sensory meridian response )reaction in a time when it was not yet discovered.
Crickets started chirping in my ears several days ago, then Sabine uploaded this video. What a coincidence! In my case, it has an obvious reason that I got hit by a bike. That audioclip just doubled my pet crickets.
"A lot of incompetent spies" Who was present at every incident? The US State Department is the only one I can think of with means and opportunity. And they're obviously present at the scene of every crime here.
@@user-db3xu1hw7r Diplomats don’t typically spy, but spies typically pose as diplomats. It’s fair to assume that nearly every embassy in the world houses a significant number of spies.
Having worked as an engineer for a low-budget RF meter company, I can say the following: First of all, such consumer devices typically have their full scale values at the lowest recommended maximum field strengths one can find. So it's not uncommon that they are overloaded even in completely healthy situations. You can buy attenuators to solve that problem. Then embassies commonly are "bombarded" with radio waves in lots of different frequencies. This is done for multiple reasons. For example some people use cellular telephones to control bombs. If there is no usable mobile telephony signal, those phones will be unable to be reached. Then there is the issue of embassies gathering radio signals from their surroundings. The more noise you send towards that embassy the less likely it is that they can get anything useful out of that. So what you'd need is a not very sensitive non calibrated RF detector which can therefore detect changes in the levels. That's not a very complicated device. An experienced RF designer can probably churn out a design for that in a few weeks which would cost much less than $100 to produce.
Acoustic levitation is a fascinating technique that utilizes sound waves to suspend and manipulate objects in mid-air. By using a passive beam array, we can create a standing wave pattern of sound waves that generate specific areas of constructive and destructive interference. In the case of acoustical levitation in a closed space like a kitchen, this technique can be employed to direct the movement of gases, bacteria, and viruses. By carefully adjusting the signals from each element of the beam array, we can create regions of constructive interference where the sound waves reinforce each other. These regions act as stable points, known as nodes, where objects can be levitated. By positioning the nodes strategically, we can suspend gases, bacteria, and viruses in mid-air. Additionally, by manipulating the standing wave, we can control the movement of these suspended particles. By adjusting the signals, we can change the location of the nodes and antinodes, effectively directing the movement of the gases, bacteria, and viruses within the closed space. Directly into their faces. This technology has the potential to be used in various applications within a kitchen setting. For instance, it could aid in the precise movement of gases to enhance cooking processes or prevent the spread of airborne contaminants. It could also be utilized for sterilization purposes by effectively manipulating the movement of bacteria and viruses, helping to maintain a clean and safe environment. In summary, the use of a passive beam array and the generation of a standing wave pattern allows for the acoustical levitation and precise manipulation of gases, bacteria, and viruses in a closed space like a kitchen. This technology has the potential to revolutionize various aspects of the culinary environment, from cooking processes to hygiene and safety measures. Microwave levitation? I want my medal. Lol.
I've always thought it would be fun, although potentially injurious to bystanders, to use directional emitters, one a fixed frequency, the other a beat oscillator, to create phantom sounds in certain areas. You approach the fishing tackle section of a big box store and hear the whizz of a reel, the plop of a lure, and the sizzle of a freshly opened beer. Could be effective marketing. Might blow our eardrums out our sinuses, but it could sell lots of fake worms.
I've seen some really sketchy stuff around THE first case. Guy literally thought "I'm being attacked by microwaves." In response to this weird health incident. Like, that's the first explanation that comes up in his mind. When a doctor tells you to wear a tinfoil hat, the world is crazy. When you tell the doctor you should've worn a tinfoil hat... not so sure.
I experienced the exact same symptoms, but the doctors were not confused. Labyrinthitis and sudden hearing loss. It cost me the hearing in my left ear, and tinnitus in the effected ear. The doctors ignored my complaints about headaches, and difficulty concentrating. "Well we don't know everything," she said left me to fend for myself. They suspect an unidentified virus. I know two people at work who had similar issues - years apart. The point of this is that those symptoms are more common than people realize, and do not rely on some conspiracy.
That doesn't explain the damage to brain neurons, however. Many of the victims have TBI's, traumatic brain injury, damaging cognitive abilities just as badly as those from car accidents. It's pretty clear Kamala Harris suffered from it when she went to Vietnam. She had disappeared from public appearances for several months after returning from that trip, and when she came back she had all the behavioral hallmarks of a TBI victim. Only in the last few weeks has she started to speak more normally again. The media claimed her security detail had discovered the Havana Syndrome attack ahead of time and had withheld her in the prior city a few days to escape it, but that's clearly baloney.
That sound is exactly what I hear, in the car, at home. I have a crystal table and I can feel it when I put the hand, like infrasound. I think are both.
I was confused around time 9:00. At one point it seemed you were saying that the ability to hear certain microwaves was an effect of stimulation of brain tissue -- which implied (I thought) that it wasn't "sound" in the ordinary sense. But then you said that the phenomenon could explain the recordings made of mystery sounds?
Sorry for the misunderstanding. It doesn't explain the recordings - you can't record those sounds - but it explains why people heard something. There is, for all I know, only one recording, which is the one that sounds like a cricket.
@@SabineHossenfelder actually depending on the microphone circuit used it could also explain the audio recording. Also, please could you please unstick the academic literature bibliography link I posted in the other comment thread?
@@SabineHossenfelder Ah good. Thanks. I was glad to hear about the crickets, not only because it was a very sensible finding (we're all much too disconnected from the natural world these days), but because, with the evidence of such a sound I would hope they would have experiment further to find any source or directionality of the sound -- which, apparently, they didn't proceed with.
You can also hear the intermodulation products of microwaves and not just the carrier frequency. A great example is a cell phone near old land lines, you can often hear data being sent that the land line picks up like an antenna even though the frequency may be in the gigahertz range because the frequency is being changed to send the data and that has frequency components under 20khz which is how you can hear them. I would expect this would also work for larger power into your head as well and make up at least some of the noise heard.
Air is a nonlinear medium for sound. An ultrasound beam can thus yield corresponding audible sounds. A student at the MIT Media Lab exploited this phenomenon to devise an "Audio Spotlight" that enables listeners in the beam to hear the modulated audio.
