It’s interesting because the animal that makes this “unidentified” noise at 3:45 turns out to be minke whales. This was just discovered not too long ago.
"Train" is already considered explained. It's not a product of submarine activity. It's due to cryoseismic activity at the Ross Sea, off the coast of Antarctica. It is unlikely any submarine would even be there. The sounds also aren't that similar. You are forgetting one major thing. "Train" is sped up 16 times. The doppler sequence in this video is in real time. If you slowed down "Train" to real time, or sped up the doppler sequence to match, and compared the sounds, they would not sound similar. In fact, you'd probably barely be able to hear the latter at all, as it has a frequency between 30-40 Hz, which is in the range of Infrasound.
@@xxfalconarasxx5659infrasound actually (🤓lol) starts below 20 Hz; and 20-60 Hz is sub bass and still within the human hearing range (varying from person to person)
The ship sounds are propeller cavitation noise. The active sonar pings are most likely from naval surface ships, not a submarine. Subs try to remain quiet at sea to prevent detection, and use passive sonar instead to listen only.
Derek Suddreth Listening or passive sonar are the same thing, listening is the passive sonar, if a submarine has to find a target too quiet to be found it uses the active sonar to flush it out
USSR submarines relied on active sonar much more than their American counterparts. If these are recordings from American subs in the 60s they definitely could have been listening in on some active Soviet sonar (or just testing their own)
I had read that in the Japanese submarine I-58, the hydrophonist had heard at a 12 mile- distance, the sound of dishes clanking; it was the USS INDIANAPOLIS approaching.
lupahole well considering as soon as the sub fires the enemy sub essentially gives its location away which allows for a counter fire shot which in that case it's no fun for both sides, unless of course the sub is 10000 yards away in which passive sonar probably wouldn't hear the transient
@@socomgaming1014 It only gives its bearing, not its depth or distance though, so a retaliation would be a blind shot. Also the launch transient could be undetected even at closer range if the enemy sub is in the baffles (and the towed array isn't deployed)
True, if the torpedo goes active right after launch though there’s a good chance of the torpedo picking up the contact, especially if it’s a mk48 ADCAP, you literally have to try to make those things miss in order for one to not hit its target
@@socomgaming1014 You guys di the world war II ? a sonar man would be either bored or scared shitless from what I hear from you. a minute you hear some dumb ass sperm whale and the other a goddam u-boat.
Nice upload, thank you, amazing sounds. Those loud fish.. i guess they don't taste good or something, i suddenly remembered seeing something about noise complaints of people living in boats (usa) the source appeared to be fish, the camera even recorded rippeling and splashing water just from the sound produced by them. Loved the shrimp feeding frenzy..it must have been a cloud and/or carpet of those creatures.
I dunno why, but u-boats are just the scariest thing in the water to me. I think if I was swimming around in the ocean, and this enormous monolithic shape began to take form from the murky depths beneath me, followed by the sound of a dreary, echoing ping sound, I'd probably faint in the water. No fucking thanks.
any idea how far the device was from the sources? mainly some of the animals. I know the natural stuff can be thousands of miles away... just curious how far animals calls travel
Idk why, but for me its the most peaceful thought to be 1000s of meters deep in the ocean. Away from the stress and the socialmedia on the top. And the echo-sound from inside the ocean sounds like...Idk like talking to each other in the space. An almost infinit echo, which stands for itsself and doesn't need commentary or interruption.
fun fact: the developers intentionally used the dolphin as inspiration for the crabsquid noises for this exact reason. the crabsquid is supposed to be a creature that lives in deep underwater caves and near the midnight zone and as such would rely more on ecolocation than vision. when you hear it clicking its actually trying to pinpoint where you are.
"4) Artificial - Ships and submarines"....... these are old recordings from WW2 or shortly after that were made by the US Navy and used for training sonar operators. HNSA has them for all to listen to whenever they wish. Contrary to a lot of the views from the video game commandos these are what things sound like in the real world, not some fantasy crap they listen to.
The "woof, woof" isn't an animal. It is artificial and probably not of this earth. I suspect it is a "black box" signal to inform others of its location.
This was a surface ship getting an echo back from a stern aspect submarine. The echo is long, drawn out because some of the returns are from the subs wake. If you listen carefully you will hear the down doppler from the sub as a discrete sound, the doppler is correct here.
Oh ok smart guy. I guess the NOAA scientists with decades of experience studying marine phenomena either know less than you do, or just lied about the identity of this recording for the lols. OF COURSE IT'S AN ICEBERG! What the heck do you think it is?
Wow, the dolphins sound really sound like listening to another language- I mean, it is; but I mean in the same way it feels listening to humans speaking in a language you don’t speak. Orcas are even more complex than bottle nose dolphins; and BOTH are have a more complex brain than humans. Orcas are very likely to be the most intelligent species on earth; but humans like to measure other animals intelligence to our ability which.. no lol. It’s not just ability to use tools that makes a creature more intelligent- i.e. Orcas: - orcas have a more complex & advanced way of communication - different pods having different dialects - individual culture and learning/ evolving from one another, like humans - babies that develop like how we do (they babble like human babies until they learn the language!!!) - “trends” like salmon hats (literally could be compared to human tiktok trends), - more complex emotions that we’ll never experience/ would literally be impossible for us the comprehend - they have an additional part of their brain we don’t More and more research is being done, so I’m hopeful sometime soon we’ll be able to understand their language! Honestly, I wouldn’t be surprised if they already understand us, but they don’t have vocal cords and speak differently
Sounds travel a LOT further underwater, and hydrophones are left idle (always recording, not always someone listening unless it detects something) and they can pick up sound from thousands of miles away; making it sorta impossible to record video unless someone is at the right place and time
