The Inaudible Sounds That Make Movies Scarier - Cheddar Explains 

They must have done that same technique in the Emoji Movie because I threw up many times while watching it

The sounds are just *wiggly air.*

its pretty much a cheat code for scary movies

That one dude that can hear the sound: "What's that annoying sound playing?" His friend: "What sound?" *throws up*

"Infra sounds are the sounds of earthquakes or atomic bombs" Oh yes yes, atomic bombs, I know exactly what those sound like

"Girls' voices get higher pitched when they talk to a guy they like" Girls talking to me:

Someone should make a cheerful happy movie with a sub base frequency to throw everyone off.

"gastrointestinal disturbances" Straight up, you guys are talking about brown noise, right?

I want to put this sound playing in the background of something not scary and see what happens.

The way you presented the sound spectrum isn't quite right... The frequency was the same in the low and high sides.

I’m Even uncomfortable listening to someone talking about this

In Germany some people suffer from the “Brummton-Phänomen“, a low frequency phenomenom, were only one person hears a low frequency at night, but not their partner. They even started an organisation. Most of the complaints come from Sachsony.

SCP-5234 Object Class: Safe Containment Protocols: SCP-5234 is to be kept in a small box inside a storage unit at all times. No one is allowed to take the CD at any time unless its for testing. Testing should only be about 30 minutes to an hour of viewing and staff are required to wear noise-cancelling headphones or exit the room with CCTV outside the room, viewing the chamber at all times. Description: SCP-5234 is a typical CD that presents a film made in 2002, which makes the viewers [ *or listeners* ] tend to vomit, feel queasy, and in worse cases, require medical attention.

It interests me that this sound frequency can induce ghostly hallucinations, anxiety and chest-pressure - all the symptoms associated with sleep-paralysis

"Mom, I'm scared, I heard something" "What it was sweetie?" "Nothing"

1:58 That graph shows decreasing amplitude (volume), not frequency. The gaps between each peak are the same all the way across, so the frequency doesn't change.

Guys, your frequency graph is just a weird amplitude/volume graph. Nothing to do with bass or ultrasound...

And kids this is why you should never go to movie theaters

"tactics to stop riots" oh well about that..

6:00 my ears no joke hurt

So Deaf people are living in a live action horror movie.

The scariest movie sound is a baby starting to stir during the opening credit...shivers

This explains why I haven't been scared by any horror movies when I watch them at home, the reason the only movie I've been scared by is one I watched in a theather, where audio was better

This has also been found to be why basements and laundry rooms are so eerie. They emit lots of infrasound, so if you suddenly get chills while doing your laundry, infrasound might be making you spooked!

I wish there was a sound to achieve the opposite, like making someone confident.

You must've played the brown note, cause my dog just $hit the floor.

This why we bigfoots just never even watch any movies out here in the woods

Jumpscare after 12:20

I think they included this sound because I felt somewhat nauseous

Why didnt he said there where jumpscares im watching this at 12am

3:15 My stomach: *feeling weird* Scream: *appears* Me: *randomly laughs*

Reminds me of when I was watching a play in 2nd grade. Microphone made this really odd, loud, low, *extremely loud* , sound. kinda like a *pack* or a *thwack* if i remember correctly. After a seconds, i feel it pass through my stomach, oof

Is it just me that's thinking "What if they use infrasound throughout the whole video"

I swear the original silent hill movie has a really low sub bass sound and some really high pitched sound that play together pretty frequently. I could barely hear them when I watched it many years ago. It was driving me crazy. My dad couldn't hear it

You know its bad when a sound causes you to *see* things

Fact about me is that I can hear very high hertz sounds. Like when someone turns on a tv. I hear this annoying pitch and I have to go to another room for it to stop. If you have the same condition please let me know.

I remember being about 8-9 years old in a music lesson, where the teacher kept whacking various large drums the whole time. Many of us talked about how we felt sick afterwards. Still remember it all these years later, and now I finally know why!

Infra-sound made an already spooky castle dungeon in- England become the scariest place in Britain. Every time tourists were led into the dungeon, they all complained of feeling really bad "vibes" in the place. Turns out that the castle operators were benefiting form the heavy duty machinery at a nearby factory . The machines were producing infra-sound that traveled through the ground and was felt in the underground dungeon.

gawd i felt that feeling a million times , when a jumpscare appears and my head feels lighter , and now i know it's just a sound.

I definitely experienced this while watching Dunkirk in IMAX

Holy shit, I finally get it. I used to live with a dude that would play his very bassy music and it always made me feel physically sick, I wanted to throw up every time his music shook the house and now I know why

lavender town: finally, a worthy opponent

Normal people: 😳😳😳 Trap music lovers: That's the deepest 808 I've ever heard 🔥🔥🔥

When I see these horror clips without ever seeing the moving I have no context what so ever, so I’m just like, “oh, so that’s what I’m missing”

I looked at the title and I was like, "wtf how do you hear inaudible noises?"

That guy is on adderall. I can feel it

Eww, now I’m gonna be scared of random stuff because the groovin’ air can give me the anxiety chemical

12:50 A sound that we’ve playing on the background of this video this whole time. Savages!!

This whole video made me feel anxious because i never knew if they were playing the sound are not well I'm not sure if the anxiety was coming from that or the sound LMAO

I edited the message and you wont know why it got a lot of like

They were definitely playing these sounds throughout the video, at a certain point I felt super uncomfortable and I kept feeling muscle spasms in my stomach.

Some of you have never done mushrooms and watched Gasper Noe’s “Enter The Void” and it shows....

19:35 Also a nice example if someone tries to argure that depression and anxiety are "Just in your head"

7:30 this dude literally just said "Celly"

Anyone else accidentally make themselves sick because they were expecting them to say "we've been playing the frequency throughout the video"?

video ends, me immediately: searching youtube for ghost frequency. Let's get our scared on!

As a storm chaser/ameteur meteorologist I believe that strong storms also produce this frequency or something to the same effect. You can usually FEEL the storm and it can cause anxiety and to make you get chills and shake uncontrollably.

your graphics depict a change in amplitude not frequency. I'm now TRIGGERED! :-D

I'm scared he's gonna play the sounds... *I'm eating ramen*

3:42 Guy talking about tension and being uncomfortable while he cannot sit still or look in any one direction for more than 0.2 seconds.

cheddar´s keeping spooktober real :-)

Time to play it during class!

So I checked out the 27hz and not only could I hear it but it became relaxing over time. . I deal with nonstop stress and anxiety and this actually helped calm me down :)

Is it bad that I like when sounds makes me shake?

The end made me scared ;-; just hope I don’t get nightmares

Dam when you take enough lsd you can see sounds. I wonder how this frequency will look like.

this discomfort may be a protection that goes back to when humans heard the bass sounds coming from herds, from avalanches, from landslides, from tsunamis or overflowing bodies of water, from rain or storm (the thunder), hurricanes, earthquakes, etc. all those can produce this kind of sound. this discomfort could be a signal to flee and look around.

thank you for advertising this! it's not often when I find an ad worth clicking!

Gosh that really scared me at me the end lol. I loved it🤣

Thats why I was so scared when i turned on my fan. Now I use an AC.

One of the best ads I’ve ever gotten

After this video can we get a soothing sound video?

I've always had very good hearing and I don't like loud music with heavy bass because it makes me nauseous. I also really, really hate horror movies, which I guess isn't at all surprising.

I’m old enough to have experienced Sensurround in theaters: essentially low rumbling sub woofers for action sequences, and I had a really hard time shaking the effects all night when I tried sleeping.

Me: *watches movie* Also me: oh shit my stomach is gone.

You actually got me with the jumpscare at the end xD

"You probably haven't seen Irréreversible but..." Wow, you don't sound presumptuous at all.

am i the only one that actually hears most of those sounds?

Fun fact - I lived about 10 years in an apartment right next to a busy capital city boulevard where in the corner of the room where I had the bed and if you put your ear against the windows (acting as membranes of a speaker) you could hear about the same frequency day and night, caused by all the traffic and the resonating frequency of the building. Basically there was a permanent low frequency resonance of the room, within the 20-30 Hz range. I had violence cases all the way from the beginning of my stay there in the first year, with a neighbor hitting me and my car for parking in his self-proclaimed parking spot, later neighbors beating their kids, fights all over the place, and it all ended up with me and my wife almost being killed by one of the neighbors, who broke into our house and beat us up, leaving me with a double jaw fracture and a deformed jaw for life. Even before this unfortunate event, I had a constant feeling all the time that something is wrong and something very bad will happen. Daily, every hour of every day, every moment of my life there. It's been almost 2 years since we moved to a much quieter place towards the peripheries, and I have never ever had that feeling again, even if we had the usual share of problems with neighbors here as well, but there is absolutely no sign of anyone becoming violent or aggressive in any way. Just an advice, if you feel unwell, if you feel like something bad is happening, if you feel tired, aggressive, anxious, put your ear against the windows, if you hear a constant hum, GET OUT and never go back. Try the speakers in your home as well, sometimes they can give off a hum as well, low enough so you're not aware of it but loud enough to mess with your mind.

Jokes on you! The electrical panel of my house is in my room and im constantly there

Cheddar: "The Inaudible Sounds That Make Movies Scarier" Me: *remembers Noroi and Occult 2009* Me: *gets war flashback*

6:34 Random Birth of a Nation clip. Strange.

So February last year I randomly started getting anxiety. Just constant, low level tension. I would wake up feeling slightly sick and go to sleep feeling tense. I also started getting paranoid, that there was someone about to enter my room. It was only five months later I found out they were testing atomic bombs across the road, and it was the low frequency sounds from the explosions that were making me uncomfortable.

As someone who went to see Paranormal Activity 2 in the theater, no amount of low bass sounds could make that dumpster fire of a movie scary.

The use of the sounds while nonlethal does cause permanent hearing loss in a lot of cases.

*W I G G L Y A I R*

This is the best and most knowledgeable video about deep bass ever! I spent a career aa s reviewer of the biggest and most profound sub woofers for theatre use and the crazy stuff in cars. They enjoy what we call the Fear Register and the baddest cars can do 160dB at 20Hz. There is a point at which the awfulness of the intensive body shaking that depsite hearing protection, people have to escape the car or literally tap out and beg for mercy. 153dB is where your eyeballs start to wobble. My deepest was 1Hz in a seacave with water lapping the roof and making a pressure wave..and once, Concorde sonic boom as a kid. Awesome video, well researched. Thanks ever so much!

I can testify to this as an experience I had with my epilepsy. Going to my friend's school, I pointed out a weird, extremely hard to hear sound that was very loud. He eagerly agreed with me, however apparently nobody else could hear it, which we both found strange. After a while it became more difficult to hear and I tried to ignore it, however this was not the end. As I left, I could no longer hear the sound, and I immediately had a seizure. After watching this video, I guess I now know what it was!

At 7:30 did he say “celli” in place of cello? Is that a thing?

I have experienced minor versions of the affects of low bass sounds when hearing loud music with VERY loud bass beats that everyone else is enjoying. But I get a strange sense of calm when watching horror movies (at least when I try to think logically) WTF?

As a music producer, I love these bass frequencies

Anyone else swear they felt it at the end

Movies aren’t scary, reality is.

"You can't hear it" Bruh I have 20-20000Hz of hearing capacity.

12:07 Me: Immediately searches up Ghost sounds

This makes a lot of sense to me. Whenever I watch horror movies, for some reason, I cover my ears during the creepy scenes. My girlfriend noticed this once and thought I was having a migraine or something. She asked me why I do that, and I told her "I honestly don't know". Crazy stuff.

I KNEW that was coming at the end!!

The last part scared me SOOOO bad I think that had the frequency

This video is GENIUS! And because of that you’ve earned another subscriber, no doubt, your going to earn more my friend, keep it up!

This is valuable information for office workers. My female co-worker was always a nice, gentle person but she started complaining one day about a sound from the air duct over her cubicle that was literally driving her crazy. But most of us guys could not hear it. It turned out to be something in the ventilation system from several floors above, and was only a problem when blowing air harder than usual. Her female hearing was probably better than mine.
