Point of correction on the dB scale. Every three dB is a doubling of power, every ten is a power of 10. For example, a 20 dB increase is 100 times more powerful. A 40 dB increase is 10,000 times more powerful.
I worked with a guy who was a submarine officer. He said that when the sub was in port they had safety precautions to disable the sonar because if a ping was accidentally emitted it could kill the divers working on the sub.
That clip of the submarine passing over the diver was absolutely terrifying. Edit: I just wanted to say, this is the most liked comment I have left in over 10 years. Cheers.
Remember, it's not only submarines that use sonar. The youtube channel SubBrief (who is an ex submarine sonar officer)has a breakdown of that exact sonar video. He says it most likely comes from a destroyer during training.
Yes, but submarines have a ridiculous power level capacity for their active sonar. They rarely use it but it can SERIOUSLY hurt anyone nearby. Theoretically both submarine or surface ship sonar can even be used as a short range weapon against enemy divers, aka:frogmen.
Correct. As usual, drive-by media fails to address the central issue before they address the stupid one. This is an Arleigh Burke class destroyer. They ping hard and often, that's their job, they are sheepdogs for the carriers. Subs do not ping active except in a dire emergency. They are wolves after the carriers, trying to avoid the attention of the sheepdogs.
I used to serve on a warship with sonar, and I’ll let you know that when sonar goes active you can hear and feel it in the ship. It’s just as annoying and frightening in real life 😂
@@KissMyFatAxe Yep the dome is on the front of ship and sound conducts faster through the metal frame of the ship than it does the water. So it is actually pretty loud. My shipmates always hated it when we had active sonar training / maintenance at night for this reason. I always thought it had a kind of musical quality - especially on the longer pulse lengths.
I found you around 2019ish 2020 when I was in a dark place and watching your videos helped me kinda pause the other stuff and escape for a few mins. I just want to thank you.
damn, I can totally relate! Its interesting how the study of Nature in all its fascinating colourful & complicated expressions can make our own individual problems feel much less significant. I often feel "Wow, I'm happy to be alive to be able to experience all this!"
It's far from quiet underwater in some places. There are some small crustacians that swim in a layer up to about 50 meters thick and they make a right racket. At night diving you can hear them the second you get in the water as they might be as shallow as 5meters in exceptional circumstances and 20m is normal for the top of the layer. You can even hear the noisy sods through the hull of some types of boat.
It's like the stand shelf sounds I hear. They crust and move water and the sound is debronable. On the teenth I heard it thirtypoop times on a dive off the coast of San Diego and the ocean floor became a red treadmill with the groaning sound of your ears. Never remove your ears or you'll regret it. I did the second time and they won't go back. I was lucky that a steam ship was sailing underneath me but most people aren't that fortunate.
Imagine a giant alien spaceship entering Earth's atmosphere and trying to get a better look at the surface by flash banging an entire hemisphere with some sort of high-intensity radar/camera
5:59 It's not just possible, it is considered an active form of defence by subs towards anyone to approaches the sub within tampering distance, a single loud pulse to knock them out and let them drown. Thankfully no one has had to experience this (that we know of anyway).
@@rewrite1239 reminds me of the video where some Somalians on flimsy wooden fishing boats tried to pick on American warships. It's safe to say who had the upper hand here.
I was a USN surface sonar tech (STG) for 20 years, mostly stationed in Hawaii. My first NEC was as an AN/SQS-26CX tech. Nowadays I imagine they can fit everything that system did inside of a PC, all the signal processing and such; but back then it consisted of about 42 cabinets filled with printed circuit boards spread out in different compartments throughout the ship. Our transmitter power supply consisted of a distribution cabinet in the front with 1 inch wide and 1/4 inch thick copper distribution bars and two 400 Hz motor generator sets, and a lube oil system. We generated 3000 amps at 80 volts for 240,000 watts of ear splitting bone shattering power. The only time we ever transmitted in port was when we were conducting source level measurements, which I believe back then was a quarterly check and consisted of setting up this monstrosity of a kingpost and boom so you could dangle a little hydrophone 1 yard away from the face of the transducer. Whenever there were divers over the side, we tagged out the transmitter power supply and the inport watch on the quarterdeck would pass the word that there are divers over the side, do not rotate screws, cycle rudders, take suction from or discharge to the sea, or operate active sonar while divers are over the side. The fathometer would get tagged out also.
@diegocesari9723 the sonar set used 240 kilowatts of power at full blast, enough to power a small neighborhood. It needed huge solid metal bars to distribute the power, because wires would be too unwieldy. They would sometimes test the sonar in port, using a special underwater microphone placed next to the transmitter ("speaker"). But the rest of the time, the power supply for the sonar was shut off and locked out while in port, to eliminate the risk of injuring any nearby divers. Additionally, the rest of the sub had to be very careful about what systems they used while divers were in the water. If they sucked in or blew out large amounts of seawater (such as for cooling large systems) it could suck in a diver, or the force of water leaving could injure/disorient them. They couldn't move any of the controls either, since they could hit a diver. Needless to say, the same went for the main propeller. I'm not a submariner, but I feel like this was a pretty good summary of what was said.
Back in the late `90's the diving community in the US was advised that they were testing new sonar technology and if you encountered it on a dive, there was even a number to call to report any adverse effects. As to diving being serene 99.999% of the time, that is mostly accurate. It can be so quiet, actually, that you can here your muscles firing and occasionally here the muscles slide against one another. I have hear joints popping hundreds of times. Never been pinged by sonar though. The weirdest thing I ever heard was a 747 landing while I was 35 meters down. Turns out, it was only a train passing and I was pretty heavily narc'd. (We were diving in a quarry and it was the first time to be kissed by nitrogen narcosis)
That’s what I remember during my diving training, just always hearing my joints pop. Made me think I was an old man. Also the noise you make while breathing
I went scuba diving in the “Great Blue Hole” off the coast of Belize once, and it was trippy. I went down to 140 feet. Scuba diving can have a calming effect though if you are reasonably proficient at it. We came from the water in the ancient past.
It's almost impossible to produce a sound over 194db in air, but a submarine's sonar, at it's upper range, can easily be the equivalent of 270db which is EXPONENTIALLY higher (that's roughly 10 million times as loud as any explosion in air). Water is much denser than air, so sound is amplified underwater, and goes further. My old diver instructor claimed sound moves through water 7x as well, the actual number is closer to 4.4x. Sonar can be absolutely deadly at close range, but thankfully that power also spreads much quicker through water, being a denser medium. At more than 10,000 meters away it might be unpleasant but likely not fatal.
@xxRANDOMxASITxGETSxx research "inverse square law". Also "Sub Brief" has some good info on sonar and it's uses/dangers. Admittedly, I'm not a submariner, I went to school to be a pharmacist. But I also do a lot of sound engineering for local bands and enjoy collecting firearms and suppressors/silencers, so I like to think I have a pretty good understanding of soundwaves and related phenomenon.
@@dark2023-1lovesoni I know very little of sound other than how to setup and tune a subwoofer/enclosure lol but I am deeply fascinated by large horns and sirens.. and apparently now sonar lol Aye how can we put that 200+dB into a 30hz bass note that's what I wanna know 😂 😅
Submarines do not have any occasion to repel boarders. DESTROYERS, on the other hand, are regularly tasked with pinging the living shit out of the water in vulnerable harbors in an effort to deter and/or incapacitate any enemy frogmen in the area.
In my AP environmental science class we learned about the types of ocean pollution and one of them was sound pollution, which I always thought was a bit weird. I didn’t know that sonar was this life-ending pressure wave underwater. It makes a lot more sense now 😂
The cavitation that comes off of the impellers of ship propulsion screws is also a significant contributor to noise pollution in the seas. That's why it's still an extremely active field of research and development to design a screw that can operate at high RPMs without cavitation. A screw that can operate at faster speeds is a screw that can generate more thrust.
@@nzoomedno, but for examples with whales when there is mapping being done (I think) for example the whales and ither fish leave that area, basically killing that part of the ocean for years
@@nzoomed The whales and dolphins which use sound for comms and have sensitive hearing probably suffer. Fish don't have hearing, or at least nowhere to that degree
While I was in the navy, we would hear SONAR pinging around the ship quite often when a sub was nearby. Was still incredibly loud even in a ship above the surface.
As a scuba diver I was actually enlightened by this revelation! thanks. BTW - I remember when you were so thankful for 2K subscribers! now you’re almost to one million!!! 😮WOW Congrats!🎉 A testament to how fun and interesting your stories/ storytelling is. keep up the intriguing topics!
Yeah so true. I scuba dived in the Great Barrier Reef and it was extremely loud and busy. Anything down there is clicking, crunching, wooshing, cracking, etc. The parrotfish munching on the coral are extremely loud lol. It’s obviously very different in the open ocean, but yeah it’s often much louder than you think!
@@MarioGoatse One thing I find that constantly amazes me, is the amount of sound that gets erased by/absorbed into all the ambient noise in any given environment. As is so often stated, sound travels better underwater than through air. So imagine how much random crap is contributing to you hearing, well, basically nothing. addendum: Across the street from my house is a little brook. Between roughly 0100 and 0600 I can hear the sounds coming from it, through my bedroom window. It is maybe 50-60ish feet away, at a 45 degree angle from that window. No obstructions. My city has 35k people, so not really that big, but for the rest of the day, no way I can hear it, even when it is really quiet right around my house... For underwater noise pollution I essentially add a 1000x multiplier to that anecdote.
The boats have always been the loudest for me. I remember the first time I ever heard a cruise ship blow their horn while I was under. Sounded like they were right on top of me, but it turned out they were at least 10 miles away. Boats are loud as hell while under water
When I was stationed in Hawaii? I became Dive certified, even though the ocean terrifies me. Once went down right outside Pearl Habors water, sat on a rock, and watched a submarine head out to sea with some Navy friends I made. It sent out a sonar the moment it got out of the small bay and the rock I was sitting on? I felt it vibrate a bit. I could even feel the sounds hit my back as they bounced off all of us and back into us off each other and the surroundings. My bones fucking vibrated. I haven't been back in the ocean since and I'm okay with that. Won't ever be recerting for diving either. EDIT because the internet judges are on full stupid. I was stationed in Hawaii at Schofield Barrack, I was a soldier, not a Marine or Sailor. I had lived there for two years by the point this story happened. I made friends in other branches, hence why I said I had Navy friends. Those friends were all dive certified and talked me into it. I went with them on a lot of outings. One of those outings was seeing a submarine under water. They all knew when it would leave and sometimes dive down to a rock culture, I was invited so I went. We sat 200ft away and were BARELY able to see the vessel. But were 1000% able to hear it.
Idk but this is legit one of my biggest fears. In the dark deep ocean, nothing to see and a just hearing this mind shattering sound maybe probably killing me. The fact 1.1k people liked my comment is like wild. Thank you guys 😂 i just woke up this morning and yall blessed my day a bit.
4:44 A common rule of thumb is that each +3 dB is a double power (for those who interested in details, 10^(3/10) is approximately equals to 2). So 180 dB sound has approximately 1,000,000,000,000 (2^40) times more power than 60dB, which is what we are used to.
The concept of deadly sound is pretty terrifying since there's absolutely nothing to protect you once the noise starts, and sonar just adds to it because you'd only hear it in the terrifying open ocean. Good thing that means it's totally avoidable for me!
@@RaccoonKCD bro... why you gotta call me out like that 🤣🤣 i just watched the Zambian Space Program video and I think it may be the best thing I've ever watched
@@francismunozcoll4490 the only thing stopping me from watching all of them on day one was because I work at a hotel and need to be available at all times
That bit about the aliens is literally the plot of Roadside Picnic. Aliens show up on Earth, everyone too close to the landings is 'blinded by a sound', they do mysterious unknown stuff but never try to communicate, and then they just leave and the places they visited are now lethally dangerous zones of bizarre anomalies and wondrous artifacts.
Can't believe you didn't bring up the humpback whale in the context of impossibly loud sonar. They have the super power of being able to click a human inside out. Though they seem to recognize this, and while interactions with divers is fairly uncommon, there's plenty of examples of humans getting a full body ultrasound, and appendages that were reaching out toward the whale were fully incapacitated for hours following the interaction.
I've been pinged whilst swimming, thankfully it must have been a safe distance off the coast, but it was very loud and disconcerting. At the time it practically made my heart stop, but just from fear
A point about the loudness, the dB scale in water is not the same as it is in air. It's about ~63ish dB less. So sonar at 230 dB can be comparable something like 170 dB in air, and for reference some whales can click at 230 dB. Its loud enough that you don't want to be near it because you might lose your hearing, but its not like going to make you explode or anything.
I mean, being right next to something that can produce 170 decibels in air isn't a good time either. A pressure wave that intense could do serious damage to your lungs because it'll affect the air in them differently than the rest of your body. Pretty sure it's also capable of rupturing blood vessels, which is definitely NOT a good thing, especially if those vessels happen to be in vital organs like the brain. You have to remember, at that point on the scale, the line between "sound" and "explosion" begins to blur. EDIT: Didn't realize he described those effects in the vid; that being said, 170 is basically like having your ears forcefully clapped or firing a handgun right next to your ear already. At that point it's no longer just hearing loss, it's "your eardrum no longer exists".
2:16 It's cool how you can hear the ping echo over and over in the full version of this clip. It's real, there's an explanation by the diver who filmed it somewhere online.
Was on a ancient SSN, and always wondered. In warm water at low speed you can hear fish and whatever making all sorts of noise. In any water or speed you could hear military sonar during war games, loud and constant. Many different tones and patterns depending on how they are searching for us, with what equipment. Interesting as hell but has to do damage.
@@achi5170 youtube commenter realizes that nothing is original, and that multiple people can have the same ideas next up: scientists find out the sky is blue and that water is wet
You get to experience this first hand without the risk of death in Barotrauma with the Real Sonar mod. and the effects it has on your body, vision and internals. It's terrifying how dangerous it is, even with the Anechoic Diving Suit there is still a risk while using it.
Each Navy has its own unique sound. Canadian sonar sounds like the ping from a movie, Japanese sonar sounds like blocks of wood being slapped together, while the American standard is a whistle sound.
I remember an episode of Unsolved Mysteries where people claimed to be bombarded by a constant noise few could hear. They called it The Hum. Attempts were made to track this source down. The show could not find an answer. One person claimed it was the US Navy's experimental sonar testing off the California coast. However, people as inland as Taos, New Mexico claim to hear this hum. The Navy's use of Extremely Low Frequency waves, or ELF, was an attempt to communicate with submerged submarines. It's been in use since the 1970s or 1980s.
I remember reading news kinda relating to that, there were scientist that was studying/observing a pod of killer whales in that area and were perplexed why they moved away from their usual area, later they found out about the sonar test and figured out that the test was actually hurting the animals and it drove them away.
I'm one of the people afflicted by the Hum. It doesn't matter where I am in the world, I can hear it. Not every day, not all the time. I don't live in AZ either.
235 decibels... That thing isn't even making sound, it's like bombs going off @ various frequencies. Sound stops @ 194db. Anything higher is a pressure wave which is what explosions make. Sperm whales can do about 230db. I feel like sperm whales have the best sonar. It sounds like a CT scanner. Clear concise clicks, in varying intensity and speed. They must see amazingly with that thing! I bet they can see the subs out there even with thier rubber skin. I bet subs try to stay away from sperm whales because their sonar gives the submarines locations up.
There is something about the sound of a real SONAR ping that is so... like it is terrifying because it does not feel like something a human could create with a device. It is so devoid of anything resembling human invention.
Your content is so good. Your reading voice is captivating, your illustrations delightful, your subject choices interesting, and your sensitivity around mortality strong. Hurrah for Qxir!!!
I think I read that some high intensity sonar can even boil the water in the immediate vicinity of the hull where it’s emitted. Imagine a sound wave that’s so loud and so intense that it boils water? That’s frickin crazy 😳
Microwaves were invented by dude testing radar equipment for a company called Radeon, Percy was a radar operator noticing.stuff cooking from the sound waves.
I would assume the boiling is due to cavitation rather than heat. The sound wave blasts the water back, leaving a vacuum, and when exposed to a vacuum water will boil into vapor even at low temperature. This vapor can move more rapidly than liquid water and start to fill the void before the liquid water has a chance to flow back from the pressure.
@@Alex-gw4dx Electromagnetic radiation heating things has been known for a long time, but what makes the microwave oven unique is the way that it selectively heats certain materials. The microwaves pass through the air in the oven unimpeded, but their frequency has been selected to match the resonant frequency of liquid water. This means any bits of water in the food will catch the heat and conduct it through the food without heating the air, the bowl, or the plate as much as a conventional oven would. This also explains why previously frozen food is so often unevenly heated, as solid ice does not catch the microwaves as well as liquid water does, so whatever part of the meal thaws first will continue to absorb more heat while the beams pass through the frozen portions. Also, the first time a device resembling a modern microwave was built was by cryogenics researchers using them to more smoothly thaw mice that had been frozen. This let them be thawed without inducing burns, which was a major limit of studying cryogenic effects. (The end result is it worked, but thawing anything larger than a hamster takes too long.)
0:40 they actually cannot turn it on at anytime. They have tags to watch out for that basically prevent them from emitting a pulse. Also, submarines aren't the only boats to use sonar. In fact, they are probably the least likely to ever use a pulse because it gives away their position. And subs are stealth vessels. The goal is to never be seen by the enemy. It's really weird how people just seem to associate sonars with subs. The pings you heard in das Boot weren't from the sub. It was the destroyers on the surface hunting it down.
Prior to my dive in Fiji yesterday-there was a large survey vessel off the coast of my hotel. Upon getting in the water the noise was absolutely insane, it shook my chest and I was confused as to whether it was somebody trying to get my attention with noise but quickly realised it must have been the vessel. Absoulotely crazy and it lasted for the whole dive, it was this kind of unmistakable low booming sound and it makes you wonder how much havoc it would wreck on marine life. Not sonar but seismic blasting is very similar, I’ve heard active sonar in person a few times but thats a story for later. For your enjoyment here is a list of sonar ua-cam.com/play/PLhCpE3jaBWTcsOBKDRXUVlzzT7pCq3hny.html
As a former mine diver i confirm this vid only thing that beats the sonar is the "underwater telephone". This is why we had to have a flag up with "diver under water". And NO ! The chance getting hit by sonar in the Baltic Ocean is realy HIGH !!! (6:05)
*Baltic Sea There's no such thing as the "Baltic Ocean" And yes, even though *colloquially* the words "sea" and "ocean" are used interchangeably, when speaking technically about *specific* bodies of water you should use technically accurate terminology.
@@rewrite1239 Yepp. The Baltic SEA is shallow water (28 meters mostly) so subs and boats and divers are ALL at the same level ... big problem. 27 meters is the max for diving with compressed air, so a lot of amateurs to this level.
I was a civilian researcher years ago in marine physics. I was participating in an exercise doing some acoustic work so we were working with the destroyers. It was horrible in my berthing area that was below the waterline. Even though the destroyers were over the horizon the sound levels made sleep almost impossible. I’d go to my rack with sponge ear protections and Mickey Mouse ears protection and it was still loud enough our hull would vibrate. Fun times.
In Norfolk I think the year was 2017 or 2018 there was an unannounced diver in the water near the destroyers. No one knew who he was with or why so we sent out teams to search for him. We only saw him surface a couple of times but no one could get to him physically so a bunch of ships were all ordered to ping their sonars at the same time. It was very loud even if you were outside the water. He surfaced shortly after.
@@KissMyFatAxe When it comes to protecting military assets we are not trained to do warning shots or detain unless it's convenient. Priority one is making sure the assets are safe, when pinging him causing harm was the intent. Many sonar techs believed it should have actually killed him and were surprised to learn he survived.
@@spartan7375 no I was on duty that day so I was stuck to my ship. The official story was that he was never found but one of the search teams reported that after the ping he surfaced and was highly disoriented, he was pulled from the water and taken away. No clue what actually happened.
When i worked in port operations for the navy we strict guidelines for active sonar and we could even tell a captain no if divers were scheduled or in the water
Ahh, I went to school for music technology, so naturally I’d learned that 180db sustained is enough to kill a person. I was hoping Qxir would deliver on this premise, and you did not disappoint.
Tangentially related, but I was diving one time in Mabul - a small island off the Malaysian Borneo coast. We were just going under the water when we heard a loud, very clear boom. After the dive, we asked our guide and he said that was from dynamite fishing miles away. We couldn't hear it above the water, but could hear it clearly underneath.
Same as movies with similar themes being released at similar times. They're likely inspired by the same real life event. In this case it was probably inspired by the search for the ocean gate sub.
I had a nightmare of a really bad fear of mine in which I was in the middle of open ocean underwater far enough to have the surface be obstructed but light still reached. I was just floating around and then heard a whales call far in the distance and then once again behind me and then repeatedly getting closer. Genuinely the worst nightmare I’ve ever had
Holy crap... the AN/SQS-26 sounds like something straight out of a horror movie. Unsettling enough to hear when you're expecting it but cannot imagine how awful it would be underwater out of nowhere and potentially loud as a jet engine.
Honestly surprised that you haven't hit a million subs yet. I thought for sure this had to be an old episode, so to do my part I shared a link to your channel with people I think might dig your channel. Keep up the good work!!
Getting run up on by a submarine is my biggest irrational fear. Not while diving , but like if my ship goes down and I’m just treading water and it’s pitch black night and all the sudden you hear the eerie churning of a “silent” engine getting louder and louder until a big metal bulbous thing comes up from underneath you. Bonus points if they have lights on or some creepy shi.
A lot of the smaller 40-100 foot sportfish yachts are starting to run sonar to track fish for tournaments.For the small one time price of 250k for an OMNI sonar. No where near as strong as military grade but still audible to humans.
Fun fact most submarine will almost never use active sonar but if you are diving and a destroyer or crusier were to pass over you than you will have to worry about being impoled by sonar
now i know what those strange sounds coming from sky and forest comes off. this is back in 2014s and 2017s people were uploading videos of hearing strange load noises.
Realistically he (or at least someone) should do an entire video on Dale's life. His entire life is actually pretty intense and very interesting, especially his relationship with his own father, Ralph Earnhardt, who was also an accomplished racer and mechanic in his own heyday. Ralph's death didn't crush Dale like most thought it would, but strengthened him. It galvanized his dream of becoming a world-famous racecar driver, and he took that dream all the way to Daytona. (After losing the 500 several times due to bad luck lol) The dude is just a straight-up icon, there's nothing else to say about it. Everybody always props up Magic Johnson or Michael Jordan as "sports heroes" but Dale Earnhardt was on the Wheaties box all the same. The dude was a legitimate legend, and his "pass in the grass" maneuver that he pulled at Charlotte was some of the best race-driving anyone's ever seen. The fact that he somehow didn't lose it going nearly 180mph on GRASS is astounding.
On the inverse, I was diving in Maui once and although I couldn't see them, I heard the Whales make noise underwater while diving... I could hear it coming from a direction until it eventually wrapped around my entire body kind of like a gust of wind coming towards you and I felt it vibrate all around my body. It was extremely soothing and pleasant. 🐋🐋🐋
it's really horrifying in an otherworldly way, like aliens, like mentioned at the end of the video (which incidentally reminded me of a futurama episode) disregarding what it could do to you, the sound alone is bone-chilling, like it was made by something beyond comprehension and you can't even see the source. adding the harmful effects, like nausea and hearing damage, or worse at closer ranges, and it's downright lovecraftian
I've never seen a submarine before. we went to the submarine (and other ship) testing site bear Ketchikan and the area was all buoyed off. We got closer than I felt comfortable with and a periscope looking thing rose from the water. I don't think it was a military submarine... probably testing equipment... but it scared me, as a youngster! 😂
Awesome content as always. you can always make your videos be incredible interesting, taking the science ad making interesting facts, Friday is Qxir day for me and many others, hope you keep making content, your efforts are awesome, who knows, maybe in the future streamers watch your channel like a religion, maybe they already do that. The internet is such a huge place but one well crafted video is able to make a loop inside the brain and keep itself stuck there for a long time.
Fun fact: if a US navy vessel was to use active sonar off the coast of Tallinn, it could kill divers off the coast of Helsinki and deafen divers off the coast of Stockholm and Saint Petersburg
That would depend entirely on alot of wavetrain variables. Additionally what type of system was being used. The fatho is active sonar technically and it's pretty much always pinging away. But it's hardly dangerous to anyone
Was fishing in Norfolk bay once and had a submarine pop up really close to our boat. It was intense…those things are huge ! That same trip when we were heading out to the bay, we got a little too close to the USS Ronald Reagan and we were warned to move further away. A memorable trip!

Hey I hope things are going okay for you these days
You doing good now mate? I hope so. ❤
damn, I can totally relate! Its interesting how the study of Nature in all its fascinating colourful & complicated expressions can make our own individual problems feel much less significant. I often feel "Wow, I'm happy to be alive to be able to experience all this!"
It's far from quiet underwater in some places. There are some small crustacians that swim in a layer up to about 50 meters thick and they make a right racket. At night diving you can hear them the second you get in the water as they might be as shallow as 5meters in exceptional circumstances and 20m is normal for the top of the layer. You can even hear the noisy sods through the hull of some types of boat.
which crustaceans are you thinking of? the only loud crustaceans I know of are pistol shrimp, but those live on the ocean floor.
When diving you hear krill and other sea life constantly. Sounds kind of like a crackling or crinkling a plastic bag.
It's like the stand shelf sounds I hear. They crust and move water and the sound is debronable. On the teenth I heard it thirtypoop times on a dive off the coast of San Diego and the ocean floor became a red treadmill with the groaning sound of your ears. Never remove your ears or you'll regret it. I did the second time and they won't go back. I was lucky that a steam ship was sailing underneath me but most people aren't that fortunate.

I was a USN surface sonar tech (STG) for 20 years, mostly stationed in Hawaii. My first NEC was as an AN/SQS-26CX tech. Nowadays I imagine they can fit everything that system did inside of a PC, all the signal processing and such; but back then it consisted of about 42 cabinets filled with printed circuit boards spread out in different compartments throughout the ship. Our transmitter power supply consisted of a distribution cabinet in the front with 1 inch wide and 1/4 inch thick copper distribution bars and two 400 Hz motor generator sets, and a lube oil system. We generated 3000 amps at 80 volts for 240,000 watts of ear splitting bone shattering power. The only time we ever transmitted in port was when we were conducting source level measurements, which I believe back then was a quarterly check and consisted of setting up this monstrosity of a kingpost and boom so you could dangle a little hydrophone 1 yard away from the face of the transducer. Whenever there were divers over the side, we tagged out the transmitter power supply and the inport watch on the quarterdeck would pass the word that there are divers over the side, do not rotate screws, cycle rudders, take suction from or discharge to the sea, or operate active sonar while divers are over the side. The fathometer would get tagged out also.
I wonder who could find this very niche comment full of complex technical jargon interesting. No offense, maybe dumb it down a little for the layman?

@diegocesari9723 the sonar set used 240 kilowatts of power at full blast, enough to power a small neighborhood. It needed huge solid metal bars to distribute the power, because wires would be too unwieldy.
They would sometimes test the sonar in port, using a special underwater microphone placed next to the transmitter ("speaker"). But the rest of the time, the power supply for the sonar was shut off and locked out while in port, to eliminate the risk of injuring any nearby divers. Additionally, the rest of the sub had to be very careful about what systems they used while divers were in the water. If they sucked in or blew out large amounts of seawater (such as for cooling large systems) it could suck in a diver, or the force of water leaving could injure/disorient them. They couldn't move any of the controls either, since they could hit a diver. Needless to say, the same went for the main propeller.
I'm not a submariner, but I feel like this was a pretty good summary of what was said.
Back in the late `90's the diving community in the US was advised that they were testing new sonar technology and if you encountered it on a dive, there was even a number to call to report any adverse effects.
As to diving being serene 99.999% of the time, that is mostly accurate. It can be so quiet, actually, that you can here your muscles firing and occasionally here the muscles slide against one another. I have hear joints popping hundreds of times. Never been pinged by sonar though. The weirdest thing I ever heard was a 747 landing while I was 35 meters down. Turns out, it was only a train passing and I was pretty heavily narc'd. (We were diving in a quarry and it was the first time to be kissed by nitrogen narcosis)
That’s what I remember during my diving training, just always hearing my joints pop. Made me think I was an old man. Also the noise you make while breathing
Nitrogen narcosis sounds scary af
The AN/SQS-26 world be terrifying. That was a horrendous noise. Especially in the ocean. Being surrounded by that much water gives me the creeps.
It made me wonder if that would be the last thing you'd hear if you were trapped and everyone was attempting to find the vessel.

I went scuba diving in the “Great Blue Hole” off the coast of Belize once, and it was trippy. I went down to 140 feet. Scuba diving can have a calming effect though if you are reasonably proficient at it. We came from the water in the ancient past.
@@richardtibbetts574i read that as great butt hole
@@richardtibbetts574 Oh jeez wow, is that why we need to drink water?
It's almost impossible to produce a sound over 194db in air, but a submarine's sonar, at it's upper range, can easily be the equivalent of 270db which is EXPONENTIALLY higher (that's roughly 10 million times as loud as any explosion in air). Water is much denser than air, so sound is amplified underwater, and goes further. My old diver instructor claimed sound moves through water 7x as well, the actual number is closer to 4.4x. Sonar can be absolutely deadly at close range, but thankfully that power also spreads much quicker through water, being a denser medium. At more than 10,000 meters away it might be unpleasant but likely not fatal.
Any videos that can teach my about this?
@xxRANDOMxASITxGETSxx research "inverse square law". Also "Sub Brief" has some good info on sonar and it's uses/dangers. Admittedly, I'm not a submariner, I went to school to be a pharmacist. But I also do a lot of sound engineering for local bands and enjoy collecting firearms and suppressors/silencers, so I like to think I have a pretty good understanding of soundwaves and related phenomenon.
@@dark2023-1lovesoni I know very little of sound other than how to setup and tune a subwoofer/enclosure lol but I am deeply fascinated by large horns and sirens.. and apparently now sonar lol
Aye how can we put that 200+dB into a 30hz bass note that's what I wanna know 😂 😅
@@junc9530I concur.
Submarines do not have any occasion to repel boarders.
DESTROYERS, on the other hand, are regularly tasked with pinging the living shit out of the water in vulnerable harbors in an effort to deter and/or incapacitate any enemy frogmen in the area.
In my AP environmental science class we learned about the types of ocean pollution and one of them was sound pollution, which I always thought was a bit weird. I didn’t know that sonar was this life-ending pressure wave underwater. It makes a lot more sense now 😂
The cavitation that comes off of the impellers of ship propulsion screws is also a significant contributor to noise pollution in the seas. That's why it's still an extremely active field of research and development to design a screw that can operate at high RPMs without cavitation. A screw that can operate at faster speeds is a screw that can generate more thrust.
So does that mean it kills all the fish in the proximity?
@@nzoomednot necessarily, but it can't be good for them
@@nzoomedno, but for examples with whales when there is mapping being done (I think) for example the whales and ither fish leave that area, basically killing that part of the ocean for years
@@nzoomed The whales and dolphins which use sound for comms and have sensitive hearing probably suffer. Fish don't have hearing, or at least nowhere to that degree
While I was in the navy, we would hear SONAR pinging around the ship quite often when a sub was nearby. Was still incredibly loud even in a ship above the surface.
As a scuba diver I was actually enlightened by this revelation! thanks. BTW - I remember when you were so thankful for 2K subscribers! now you’re almost to one million!!! 😮WOW Congrats!🎉 A testament to how fun and interesting your stories/ storytelling is. keep up the intriguing topics!
The underwater soundscape can be anything but peaceful at many times. It depends on how much is going on.
Yeah so true. I scuba dived in the Great Barrier Reef and it was extremely loud and busy. Anything down there is clicking, crunching, wooshing, cracking, etc. The parrotfish munching on the coral are extremely loud lol. It’s obviously very different in the open ocean, but yeah it’s often much louder than you think!
@@MarioGoatse One thing I find that constantly amazes me, is the amount of sound that gets erased by/absorbed into all the ambient noise in any given environment.
As is so often stated, sound travels better underwater than through air. So imagine how much random crap is contributing to you hearing, well, basically nothing.
addendum: Across the street from my house is a little brook. Between roughly 0100 and 0600 I can hear the sounds coming from it, through my bedroom window. It is maybe 50-60ish feet away, at a 45 degree angle from that window. No obstructions. My city has 35k people, so not really that big, but for the rest of the day, no way I can hear it, even when it is really quiet right around my house... For underwater noise pollution I essentially add a 1000x multiplier to that anecdote.
The boats have always been the loudest for me. I remember the first time I ever heard a cruise ship blow their horn while I was under. Sounded like they were right on top of me, but it turned out they were at least 10 miles away. Boats are loud as hell while under water
When I was stationed in Hawaii? I became Dive certified, even though the ocean terrifies me. Once went down right outside Pearl Habors water, sat on a rock, and watched a submarine head out to sea with some Navy friends I made. It sent out a sonar the moment it got out of the small bay and the rock I was sitting on? I felt it vibrate a bit. I could even feel the sounds hit my back as they bounced off all of us and back into us off each other and the surroundings. My bones fucking vibrated.
I haven't been back in the ocean since and I'm okay with that. Won't ever be recerting for diving either.
EDIT because the internet judges are on full stupid. I was stationed in Hawaii at Schofield Barrack, I was a soldier, not a Marine or Sailor. I had lived there for two years by the point this story happened. I made friends in other branches, hence why I said I had Navy friends. Those friends were all dive certified and talked me into it. I went with them on a lot of outings. One of those outings was seeing a submarine under water. They all knew when it would leave and sometimes dive down to a rock culture, I was invited so I went. We sat 200ft away and were BARELY able to see the vessel. But were 1000% able to hear it.
?
I see they didn’t have a written test(?)
So you don't know if you were stationed in Hawaii, or if you were sitting on a rock? the ?'s so I call BS.
the air wont vibrate, sonar works only under water. I call BS

4:44 A common rule of thumb is that each +3 dB is a double power (for those who interested in details, 10^(3/10) is approximately equals to 2). So 180 dB sound has approximately 1,000,000,000,000 (2^40) times more power than 60dB, which is what we are used to.
jesus christ
So how much louder is 230db compared to 100db?
Correction, that means exactly 10x louder every 10dB, so from 60 to 180, that is 10¹², as you written.

Can't believe you didn't bring up the humpback whale in the context of impossibly loud sonar. They have the super power of being able to click a human inside out. Though they seem to recognize this, and while interactions with divers is fairly uncommon, there's plenty of examples of humans getting a full body ultrasound, and appendages that were reaching out toward the whale were fully incapacitated for hours following the interaction.
It's the Sperm Whale that is extremely loud. It has a biological sonar of 230dB. Humpback's can sing loudly but more in the range of 180dB max.
@@MrWeebable Yes! Sperm whale! I apologize. Memories suffering from data corruption 🐋😵💫

🤯
Whales emit infrasound, no?
I've been pinged whilst swimming, thankfully it must have been a safe distance off the coast, but it was very loud and disconcerting. At the time it practically made my heart stop, but just from fear
I was pretty sure I wasn't going diving any time soon, but this convinced me
3:38 if I heard that, underwater in the deep ocean I'd sht my wetsuit.
It sounds like a high pitched recorder😂
A point about the loudness, the dB scale in water is not the same as it is in air. It's about ~63ish dB less. So sonar at 230 dB can be comparable something like 170 dB in air, and for reference some whales can click at 230 dB. Its loud enough that you don't want to be near it because you might lose your hearing, but its not like going to make you explode or anything.
I mean, being right next to something that can produce 170 decibels in air isn't a good time either. A pressure wave that intense could do serious damage to your lungs because it'll affect the air in them differently than the rest of your body. Pretty sure it's also capable of rupturing blood vessels, which is definitely NOT a good thing, especially if those vessels happen to be in vital organs like the brain.
You have to remember, at that point on the scale, the line between "sound" and "explosion" begins to blur.
EDIT: Didn't realize he described those effects in the vid; that being said, 170 is basically like having your ears forcefully clapped or firing a handgun right next to your ear already. At that point it's no longer just hearing loss, it's "your eardrum no longer exists".
2:16 It's cool how you can hear the ping echo over and over in the full version of this clip. It's real, there's an explanation by the diver who filmed it somewhere online.
Was on a ancient SSN, and always wondered. In warm water at low speed you can hear fish and whatever making all sorts of noise. In any water or speed you could hear military sonar during war games, loud and constant. Many different tones and patterns depending on how they are searching for us, with what equipment. Interesting as hell but has to do damage.

I remember an episode of Unsolved Mysteries where people claimed to be bombarded by a constant noise few could hear. They called it The Hum. Attempts were made to track this source down. The show could not find an answer. One person claimed it was the US Navy's experimental sonar testing off the California coast. However, people as inland as Taos, New Mexico claim to hear this hum. The Navy's use of Extremely Low Frequency waves, or ELF, was an attempt to communicate with submerged submarines. It's been in use since the 1970s or 1980s.
I remember reading news kinda relating to that, there were scientist that was studying/observing a pod of killer whales in that area and were perplexed why they moved away from their usual area, later they found out about the sonar test and figured out that the test was actually hurting the animals and it drove them away.
Not sure they use ELF anymore, I live an hour from the post, and there hasn't been activity there for quite some time
I'm one of the people afflicted by the Hum. It doesn't matter where I am in the world, I can hear it. Not every day, not all the time. I don't live in AZ either.

'in depth '...love it !
Absolutely crushed it with that pun!
235 decibels... That thing isn't even making sound, it's like bombs going off @ various frequencies.
Sound stops @ 194db. Anything higher is a pressure wave which is what explosions make.
Sperm whales can do about 230db. I feel like sperm whales have the best sonar. It sounds like a CT scanner. Clear concise clicks, in varying intensity and speed. They must see amazingly with that thing! I bet they can see the subs out there even with thier rubber skin.
I bet subs try to stay away from sperm whales because their sonar gives the submarines locations up.
@@brandonhoffman4712You’re not entirely correct but also not entirely wrong and yeah sperm whales are absolutely ridiculous creatures.

I think I read that some high intensity sonar can even boil the water in the immediate vicinity of the hull where it’s emitted. Imagine a sound wave that’s so loud and so intense that it boils water? That’s frickin crazy 😳
Microwaves were invented by dude testing radar equipment for a company called Radeon, Percy was a radar operator noticing.stuff cooking from the sound waves.
@@Alex-gw4dx I didn’t know that. Thanks. Interesting 🤔
I would assume the boiling is due to cavitation rather than heat. The sound wave blasts the water back, leaving a vacuum, and when exposed to a vacuum water will boil into vapor even at low temperature. This vapor can move more rapidly than liquid water and start to fill the void before the liquid water has a chance to flow back from the pressure.
@@Alex-gw4dx Electromagnetic radiation heating things has been known for a long time, but what makes the microwave oven unique is the way that it selectively heats certain materials. The microwaves pass through the air in the oven unimpeded, but their frequency has been selected to match the resonant frequency of liquid water. This means any bits of water in the food will catch the heat and conduct it through the food without heating the air, the bowl, or the plate as much as a conventional oven would. This also explains why previously frozen food is so often unevenly heated, as solid ice does not catch the microwaves as well as liquid water does, so whatever part of the meal thaws first will continue to absorb more heat while the beams pass through the frozen portions.
Also, the first time a device resembling a modern microwave was built was by cryogenics researchers using them to more smoothly thaw mice that had been frozen. This let them be thawed without inducing burns, which was a major limit of studying cryogenic effects. (The end result is it worked, but thawing anything larger than a hamster takes too long.)
so how hard do i have to scream at a chicken to cook it?
0:40 they actually cannot turn it on at anytime. They have tags to watch out for that basically prevent them from emitting a pulse. Also, submarines aren't the only boats to use sonar. In fact, they are probably the least likely to ever use a pulse because it gives away their position. And subs are stealth vessels. The goal is to never be seen by the enemy. It's really weird how people just seem to associate sonars with subs. The pings you heard in das Boot weren't from the sub. It was the destroyers on the surface hunting it down.
"Wanna hear the most annoying sound in the world?"
Submarine:
Prior to my dive in Fiji yesterday-there was a large survey vessel off the coast of my hotel. Upon getting in the water the noise was absolutely insane, it shook my chest and I was confused as to whether it was somebody trying to get my attention with noise but quickly realised it must have been the vessel.
Absoulotely crazy and it lasted for the whole dive, it was this kind of unmistakable low booming sound and it makes you wonder how much havoc it would wreck on marine life.

I was a civilian researcher years ago in marine physics. I was participating in an exercise doing some acoustic work so we were working with the destroyers. It was horrible in my berthing area that was below the waterline. Even though the destroyers were over the horizon the sound levels made sleep almost impossible. I’d go to my rack with sponge ear protections and Mickey Mouse ears protection and it was still loud enough our hull would vibrate. Fun times.
In Norfolk I think the year was 2017 or 2018 there was an unannounced diver in the water near the destroyers. No one knew who he was with or why so we sent out teams to search for him. We only saw him surface a couple of times but no one could get to him physically so a bunch of ships were all ordered to ping their sonars at the same time. It was very loud even if you were outside the water. He surfaced shortly after.
It must have been low intensity pings. I can't imagine they wanted to actually harm the guy.
@@KissMyFatAxe When it comes to protecting military assets we are not trained to do warning shots or detain unless it's convenient.

@@spartan7375 no I was on duty that day so I was stuck to my ship. The official story was that he was never found but one of the search teams reported that after the ping he surfaced and was highly disoriented, he was pulled from the water and taken away. No clue what actually happened.
You guys are psychotic. Didn’t even investigate the unknown diver or medical state. As you said, intent was to kill him/her.
When i worked in port operations for the navy we strict guidelines for active sonar and we could even tell a captain no if divers were scheduled or in the water

A while ago I went down the sonar rabbit hole, AND IT IS TERRIFYING
Tangentially related, but I was diving one time in Mabul - a small island off the Malaysian Borneo coast. We were just going under the water when we heard a loud, very clear boom. After the dive, we asked our guide and he said that was from dynamite fishing miles away. We couldn't hear it above the water, but could hear it clearly underneath.
The examples of differnt Sonar sounds in this video could easily be part of a horror movie soundtrack.
Ahh my favorite irish knowledge lender. Always a joy...
What is interesting to me, how several creators end up with similar topics to cover and suddenly all my feed populated with similar videos.
Same as movies with similar themes being released at similar times. They're likely inspired by the same real life event. In this case it was probably inspired by the search for the ocean gate sub.
In this instance you can blame the submarine logitec incident
I had a nightmare of a really bad fear of mine in which I was in the middle of open ocean underwater far enough to have the surface be obstructed but light still reached. I was just floating around and then heard a whales call far in the distance and then once again behind me and then repeatedly getting closer. Genuinely the worst nightmare I’ve ever had
Just adding this for context, military submarines will only use passive since using active will give their location away.

Fun fact:the transmitter of sonar is so powerful that it creates cavitation bubbles around the sorrounding water
A lot of the smaller 40-100 foot sportfish yachts are starting to run sonar to track fish for tournaments.For the small one time price of 250k for an OMNI sonar.
No where near as strong as military grade but still audible to humans.
Audible sure, but at the low intensity they operate, not at all dangerous
Bro, @3:30 -ish, enjoy your conversations with MI-5 and the FBI. I know it's all unclassified, but... Great video.
these videos are getting so much more high quality, love it
I definitely do *not* want "Jumpscared while diving" on my tombstone, thank you very much
I thought that the person in the thumbnail was dunking a basketball
Fun fact most submarine will almost never use active sonar but if you are diving and a destroyer or crusier were to pass over you than you will have to worry about being impoled by sonar
ill be honest, it should be a crime about how your just at 966K subs. underrated asf. keep up the great work man
SUB'S you say?
@@Nate-bd8fg yeh
2:38 Correct and that’s not accidental. A submarine is by design not to be seen.
now i know what those strange sounds coming from sky and forest comes off. this is back in 2014s and 2017s people were uploading videos of hearing strange load noises.
You should do a final moments episode on dale earnhardt. His story is intense.
The movie 'Blink of an Eye' does a good job of putting it in perspective.
Realistically he (or at least someone) should do an entire video on Dale's life.
His entire life is actually pretty intense and very interesting, especially his relationship with his own father, Ralph Earnhardt, who was also an accomplished racer and mechanic in his own heyday.
Ralph's death didn't crush Dale like most thought it would, but strengthened him. It galvanized his dream of becoming a world-famous racecar driver, and he took that dream all the way to Daytona. (After losing the 500 several times due to bad luck lol)
The dude is just a straight-up icon, there's nothing else to say about it. Everybody always props up Magic Johnson or Michael Jordan as "sports heroes" but Dale Earnhardt was on the Wheaties box all the same.
The dude was a legitimate legend, and his "pass in the grass" maneuver that he pulled at Charlotte was some of the best race-driving anyone's ever seen. The fact that he somehow didn't lose it going nearly 180mph on GRASS is astounding.
Wanna see a diving related horror game with these sounds now
Have you heard of Subnautica? 😅
Try Barotrauma with the Real Sonar mod
On the inverse, I was diving in Maui once and although I couldn't see them, I heard the Whales make noise underwater while diving... I could hear it coming from a direction until it eventually wrapped around my entire body kind of like a gust of wind coming towards you and I felt it vibrate all around my body. It was extremely soothing and pleasant. 🐋🐋🐋
Cool story man
This is the first video I have seen of yours. I am subscribing! Only 2000 more to 1 million!
Gee, thanks man. Now that I know 200+db transducers exist I will forever want one. I hope you're happy.
it's really horrifying in an otherworldly way, like aliens, like mentioned at the end of the video (which incidentally reminded me of a futurama episode)
disregarding what it could do to you, the sound alone is bone-chilling, like it was made by something beyond comprehension and you can't even see the source. adding the harmful effects, like nausea and hearing damage, or worse at closer ranges, and it's downright lovecraftian
I've never seen a submarine before. we went to the submarine (and other ship) testing site bear Ketchikan and the area was all buoyed off. We got closer than I felt comfortable with and a periscope looking thing rose from the water. I don't think it was a military submarine... probably testing equipment... but it scared me, as a youngster! 😂
Former Submarine Sonar Operator here. I can tell you we almost never went active with our boats primary sonar system.
Happy almost million subs gratzzz 🎉🎉
Awesome video as always!
0:25 I’ve had nightmares before but god damn
PTSD moment, i miss Soap
4:47 correct me if I'm wrong, but wouldn't it be an exponential scale and not a logarithmic scale?
It is logarithmic. Check out the formula for sound intensity and then look at the one for decibels and it might make more sense.
@Tact012 okay fair. I guess it's just odd that after saying its logarithmic, he shows an exponential graph
That Snoop Dogg cut is the reason I love this channel.. That and dudes accent gently shakes the gaelic ancestral part of me awake
Ouch thanks for the ear bleeding beeping sound at the beginning of your video😢
As a barotrauma player (also playing with the realistic Sonar mod) I can confirm that this is true.
Awesome content as always. you can always make your videos be incredible interesting, taking the science ad making interesting facts, Friday is Qxir day for me and many others, hope you keep making content, your efforts are awesome, who knows, maybe in the future streamers watch your channel like a religion, maybe they already do that. The internet is such a huge place but one well crafted video is able to make a loop inside the brain and keep itself stuck there for a long time.
Oh yeah, Friday def QXIR day. Look forward to it the whole rest of my miserable week.
Stay away from drugs kids, or you'll end up like this man.
Fun fact: if a US navy vessel was to use active sonar off the coast of Tallinn, it could kill divers off the coast of Helsinki and deafen divers off the coast of Stockholm and Saint Petersburg
*looks up Tallinn*
Wow good thing I definitely know how far away from each other any of those places are
@@tombo6245 Tallinn is about 300 km west of Saint Petersburg, 300 km east of Stockholm and just over 80 km south of Helsinki
That would depend entirely on alot of wavetrain variables. Additionally what type of system was being used. The fatho is active sonar technically and it's pretty much always pinging away. But it's hardly dangerous to anyone
Was fishing in Norfolk bay once and had a submarine pop up really close to our boat. It was intense…those things are huge ! That same trip when we were heading out to the bay, we got a little too close to the USS Ronald Reagan and we were warned to move further away. A memorable trip!
been watching this channel ever since I came across the Killdozer episode. Your work is so good.
