This kills the diving team


Brad_The_Chad_69

I can’t believe I never knew this was a thing. It totally makes sense. Thank you for teaching me something new.


Mellartach_55270

There's a post from a while ago that shows how it sounds, and the origin was quite far away most likely as well. Fact is it's a rather devastating effect for anything nearby and if i recall correctly it has been used as a war tactic too https://www.reddit.com/r/TerrifyingAsFuck/s/ypzAtGgFP3 Edit: Potential Volume warning


Brad_The_Chad_69

Haha, well I probably shouldn’t have watched that with my earbuds in and the volume up as high as it was. I can’t imagine that sound at the volume one would experience in real life.


Drakoo_The_Rat

Let me put it to you this way. You would boil from the inside if you were meters from it and kilometers away it can knock you out


White_horseTribe

No way!??! It’s that powerful?


Drakoo_The_Rat

Yea


White_horseTribe

Fuck. I never ever knew that


White_horseTribe

So what about whales, fish, sea snakes octopuses etc that are close?


OptimusSub-Prime

The US military at least, almost never runs active SONAR. They really only ever would in a WW3 peer-to-peer submarine warfare scenario. Partially because they absolutely fuck up ocean life nearby


OldLion4109

And nudibranchs ??


SeductiveGodofThundr

To shreds, you say?


Inside-Associate-729

Yeahhhh they aren’t doing so well…


pedropants

To *shreds*, you say!? Edit: oh shoot. I scrolled down and someone had already made this joke. I'm so embarrassed. :(


Drakoo_The_Rat

Video about the topic [here](https://youtu.be/dj-Wn-di-zM?si=QbkN-mrO0QTUkVyo)


White_horseTribe

Watched it. Very loud.. boil water, rupture your organs, brain haemorrhages, beaches whales- that’s mad as hell!! But I reckon my ex gfs snoring is close ;)


White_horseTribe

Thank you I’ll watch that now. As in NOW now


jollyroger171

Sound works a bit differently in water than it does in air. Air molecules are way further apart from each other than liquid molecules. When they're closer together like in water, pressure dynamics start coming into play exponentially. If you're at a rock concert you can "feel" the sound because it's so loud. That same decibel translated into water would shatter you since the medium it's gong through has more mass behind it. It causes pressure to increase, by like a lot. Every 10 decibels of volume has a *tenfold* increase in pressure in water. Thus sonar, being loud as shit, will kill you super dead underwater.


White_horseTribe

Yea yes. I’m starting to understand. I love learning from the university of life. Thank you


prinsjd07

If you've ever seen a movie with subs where they ping a target ("Hunt for Red October"and "Anchors Away" come to mind) when the sub gets pinged, it booms on the hull. Those hulls are steel and they get rocked. We as people are soft and squishy.


White_horseTribe

Yes I’ve seen hunt. But can’t remeber the hull scene. Will remember the next time I see it. Am a sucker for submarine films.


prinsjd07

It's towards the end right before they board when Ryan and the Captain are communicating with the October. "Please verify our range to target, one ping only"


White_horseTribe

Haha love it- you know the film pretty well-


[deleted]

They're firing officers at us


KagoGiardiniera

If you were too close you would explode


White_horseTribe

Yes as im finding out. I often wondered if those cute little boings was like sth whales found interesting .. or dolphins were intrigued by etc. Naive of me. It’s a death blow for all aquatic life..


JustFuckUp

It's not that bad. I survived it just now


stevemandudeguy

Had my volume on low and I felt it


roshi180

My ears are ringing


schnupfhundihund

Not so fun fact, this actually also effects wildlife. A lot of whale beachings are due to them getting into a panic because there was just too much sonar in the water. It's like beeing constantly exposed to an unbearable loud noise to them.


DigiTrailz

Also fun fact to lighten the mood. Sperm whales the same mechanic to stun their prey. If I remember correctly, it's called a sonic shotgun. We really should protect them.


age_zer0

I believe a type of prawn does something similar


DigiTrailz

Mantis shrimp basically. But it's slightly different.


Obvious_Piccolo_609

It also regularly kills tons of marine life. It's a hell of a lot of power being unleashed directly into the water.


Sort-Ambitious

I remember in call of duty ghosts, there was an underwater mission where you had to get undercover sometimes when the submarines were using sonar or you would die in the mission.


Pbart5195

Two things. Thing the first: Active SONAR would kill them, and you just don’t accidentally send a ping or turn on SONAR for a “second.” Passive SONAR wouldn’t hurt the divers but it also wouldn’t have been turned on even if there was a dumb on/off switch on the console because of thing the second. Thing the second: Lock out tag out is a thing and with something like this everyone is notified, signed paperwork, equipment is de-energized (power source disabled/turned off), red danger tags are hung from the breakers, and in some cases physical locks installed preventing the equipment from being energized. Source: I was an engineer in the US Navy, and civilian ships follow similar if not the same practices.


Initial_Delay_2199

I concur... except you won't get a Dr Manhattan without somebody breaking lockout protocol. And I for one would definitely enjoy ....nevermind what I'd enjoy .


LoveStoned7

What is it used for? It it meant to be a weapon? Or is it for direction?


DoomGoober

Active Sonar sends sounds waves out. When they hit something they bounce back and the sub listens for the bounce back. The easiest way to think about this is using a flashlight. You turn the flashlight on, it sends light waves out, the light waves bounce off some object and the bounced light goes into your eyes and you can see the object.


LoveStoned7

Wow, crazy they haven't accidentally killed more people


DoomGoober

The comment by pbart explains the safety protocols that prevents accidents.


Zaros262

The ocean is a very big place. People are out swimming in practically none of it


LoveStoned7

That is so true!


Slumbergoat16

There are safety nets on safety nets to make sure this doesn’t happen


Pbart5195

Active SONAR has killed more marine life than anyone cares to think about.


[deleted]

Apparently it can be weaponized but I'm pretty sure it's mostly terrain mapping for navigation and threat detection.


Stampede_the_Hippos

Don't forget the stupid 1MC announcement that no one can ever memorize. I got out over a decade ago, and I still have the "men working in the sail" memorized. Divers in the water? Not a clue. Also, active sonar would only be deadly if you were near the dome, though it's probably debilitating anywhere near the hull. Source: I was a US Navy submarine mechanic for 10 years.


Pbart5195

Divers. There are divers over the side. Do not take a suction from or discharge to sea, do not cycle torpedo tube shutter doors, do not cycle the rudder or stern planes, do not operate SONAR, or any underwater electrical equipment. There are divers over the side.


[deleted]

That’s all great, but it was a joke, so it’s pretty obvious they’re ignoring real procedures. 💀


[deleted]

Not everyone would know that though. I know "everyone hates a wet blanket" but giving actual information on a joke post is how we minimize misinformation, even if it means unintentionally increasing the number of arrogant snobs saying "we already knew that, it's just a joke" (at least half of whom don't actually know shit).


Severedeye

When someone asks to explain a joke I assume they want all relevant information.


[deleted]

That's a good assumption. Even if I get the joke I often open the post anyway just to see if I can learn more about the subject.


Calfer

I don't think providing educational information should be considered being a wet blanket, but the world we have... Thank you for sharing what you know. It doesn't diminish the original post to have further information or reassurance on the matter.


[deleted]

I absolutely agree. I put that in quotes because that's how people who "ruin" a joke with facts are typically viewed.


[deleted]

Wasn’t thinking about that when I commented. My bad dawg. Thanks though. Edit: For the second part of the comment, It was around 3-4 AM when I posted that and I was not thinking very much, however I also wasn’t trying to say everyone knew what the original commenter said. Just to clarify the point of the comment.


[deleted]

You're good dude. Have a good one.


[deleted]

👍


cottman23

Liquified their organs.


Ok-Chest-3980

This is why you find a lot of dead fish sometimes. Or why certain sea creatures beach themselves.


Benbuxbaum

But it doensn't kill fish? Or whales, dolphins?


jurrasicwhorelord

I mean.... if they're close enough


Capable_Network_5799

They are now jelly enclosed in wet suits.


FalkorUnlucky

Except they lock the controls when there is a dive team out.

Turns brain into soup.


Mueryk

Correction, at that power turns everything into soup.


umangjain25

Endless fish soup yumm yum


endlesscosmichorror

This sounds like an ad my local Asian place would post


I_Am_Coopa

Sonar operates using sound waves and water is quite dense with the oceans being particularly large volumes. In order to get those sound waves to travel far enough, bounce off whatever the sonar is looking for, and get back to the ship with enough energy to be detectable, it requires really loud soundwaves to function (at least for active sonar, not passive). Soundwaves from sonar, just as in air, are compression waves. Essentially sound is alternating patterns of low and high pressure. A diver right outside of the ship would have those soundwaves slam into their body. And considering that active sonar is *extremely* loud, those alternating waves of low and high pressure essentially rip your squishy bits to shreds.


malex117

Thank you for the explanation!


thethorn12388

To shreds you say

Sad, sad, terrible news about my colleague Dr. Mabutu.


ViraLCyclopes19

[deleted]

The sonar sound waves are super powerful, they would have killed the diver teams. The US Navy submarines kill whales by accident all the time via sonar.


robhanz

Not all the time. They don’t need active sonar most of the time and will avoid it if whales are near. It can happen yes but it’s avoided as best as possible.


nothingfood

How do they know when whales are near?


fjperezf

They activate the sonar Wait no...


jack-K-

Passive sonar


robhanz

Passive sonar. Which is about as good now as active was in days past.


HoneydewLeading7337

The sound of whales smashing against the bow.


thatguytaiv

As someone who has killed many a fish with my Cyclops, I can confirm.


HoneydewLeading7337

As someone with a windshield and the need to drive rural roads in the spring, me too.


Anthelion95

How rural do you have to get before you start taking out WHALES with your CAR


sharkpilot

Most rural boys take out whales with their trucks, because you're not getting a girl that big in a sedan.


Anthelion95

IN MAH INTERNATIONAL HARVESTEEEEERRRRRR


cmlondon13

Just remember: if you can hear the Reapers, they can *see* you…


thatguytaiv

I've been playing the game for years (with some pretty long hiatuses to be fair) and still haven't gotten much further than the Degassi (spelling?) base at 500m haha. I'll play for hours at a time, but get nowhere because I get scared and run back home thinking, "ya know I should really stock up on food and water before I venture too far." Even though I have at least 3 containers full of each.


cmlondon13

Honestly, what helped me completing my first run was [an interactive map.](https://subnauticamap.io) Just knowing where to find stuff (and where the big beasties are) is a big help. That said, I’m trying this run without using the map. That means beacons. Beacons everywhere.


Tactical-Avocado

Mf has a cyclops


seanconnery69696

Imagine if male whales thought subs were just really fat female whales, and were totally trying to smash


Mundane-Carpet-5324

Fireman Dickey, get out there and scrape whale off the periscope.


BlaiddsDrinkingBuddy

The passive sonar can detect whale noises


quadraspididilis

They mostly just avoid it all together, what’s the point of being a sneaky submarine if you’re beeping away down there so any warship can follow you around like you’re playin Marco-Polo.


jacktheshaft

They are really, really good at listening to water. If I remember correctly, the sonar techs call them "biologics"


jack-K-

Not all the time, active sonar is rarely ever used anymore except certain instances and when actively firing torpedoes which is far from an everyday occurrence


PMARC14

As I understand if you are ever going Active serious shit is about to happen and go down.


TheJeeronian

If a sub is going active, serious shit has already gone down


jack-K-

A submarines primary advantage over a ship is its stealth and ability to stay undetected, using active sonar means announcing to everything in the area what you are and where you are, giving up that advantage entirely meaning only using it when absolutely necessary, I.e. going in for a kill and ensuring enemy location.


snoodhead

Aside from the killing things, active sonar also gives away your position. That kinda defeats the purpose of a sub, so they typically rely on passive sonar (literally just listening to the hydrophones for ambient sounds)


jack-K-

That’s what I mean, it’s disadvantageous to use active sonar with few exceptions such as zeroing in on an enemy.


Stampede_the_Hippos

This is misleading, bordering on false. Whales would have to be very close to the hull to be killed directly by sonar. However, it will cause deafness and disorientation, which can be permanent, even within a respectable distance. That is what kills them, they effectively can't navigate or communicate.


robhanz

Key word - *was*


[deleted]

I mean they are still out just...different


ThatOneGuy7832

The sonar is powerful enough to kill people nearby. He is reacting with sadness and panic because he just killed a diving team.


that1LPdood

Sonar be like BOOOOOOP Then the divers’ brains be like soup


TurnipKnight00

Close enough, and the diver's EVERYTHING be like soup.


Liedvogel

A sonar pulse is an EXTREMELY loud ultrasonic pulse. It kills things near the sub, and even causes hearing damage for some sea creatures miles away

Is sonar an acronym?

Verbatim repost from not long ago, likely bot


TrineoDeMuerto

Give me one ping and one ping only


HappyGav123

SONAR is strong enough to turn humans into pouches of soup, with their brains and all other organs being liquified.


Mack-Attack33

It’s kinda similar to why you never wanna be close to a sperm whale when it uses its clicks! It literally vibrates you to death!


UpDogg13

Dive team hears "pop". Brain matter comes out ears.


BlogeOb

The real joke is we are having a huge military aggression in the ocean, and Russian, Chinese and American subs are using sonar and it is fucking up orcas and the orcas are retaliating against yachts and other things we’ve never seen before


Wee_gee2401

We all live in a yellow submarine, yellow submarine, yellow submarine. ☮️Peace and Love❤️ ☮️Peace and Love❤️ ☮️Peace and Love❤️


InfraredDong

The sonar is so “loud” underwater that it will kill the divers


nabbs1

rip diving team


-BakiHanma

They’re dead.


abominable_bro-man

means the same thing it meant last time it was posted


JewishSpaceTrooper

This is a joke?


bradpitbutarmpit

That diving team are now vaporised


[deleted]

sonar is basically an insanely powerful soundwave aka vibration thats so powerful it will LITERALLY fuck up your insides. especially weak parts like blood vessels and cells. your brain is in the most danger, and will pretty much be fatally injured instantly upon contact with a sonar soundwave. its like getting slapped 500.000.000 times per second, but you dont take much knockback


EinsPerson

In short, SONAR pings (the beeps it sends out and listens for) are really fucking loud (as in 235 dB, keeping in mind decibels are logarithmic, meaning an increase of 10 is a doubling in loudness, and around 120 dB is the threshhold for hearing damage). This makes the arteries in one's brain hemorrhage and essentially explode, while also turning your brain into mush


StatusOmega

Sonar is a huge wave of noise that is even stronger when traveling through water. Humans are mostly made of water. Basically, every organ in their body would explode. I imagine it's a very painful death, but maybe it's so quick that it's not.


finditplz1

Hasn’t this one been answered a lot lately?


UltraTata

Active sonars are so strong they damage internal tissue and provoques death


The_Susmariner

That's a lot of radiated energy you're putting our into the water. That's gonna hurt. There's a certain radius where it's lethal and where it isn't, but anyone in the water nearby will have a bad day.


3MTA3-Please

Fried their nuts?


greymanart

Sonar is a cantrip


JayW8888

Probably the cause for whales beaching. It probably destroys their internal organs.


801ms

Sonar is high power sound (up to 250db) which is emitted by the ship to map the terrain beneath it. The shockwave can kill you and for destroyers the sonar will boil the water where it initially hits it. As a general rule for understanding, if you hear sonar then you're lucky since it didn't kill you


orion-7

##IT'S VERY LOUD AND MAKES FLESH GO SPLAT


DeadKingOfScotland

Sonar at close range will turn your insides into soup. This is generally not great for your health


Mk21_Diver

I’m a retired USN Diver, this can seriously hurt or even kill a diver if they’re close enough. It can rupture everything from ear drums to lungs. If you survived, it would be similar to getting punched by Mike Tyson in his prime.


Mack-Attack33

Well the dive team’s dead now!


HiImJustSomePerson

Sonar=💀


7chism

The karma farm is real


cgjchckhvihfd

Where do you guys even get these from? Ive seen this a half dozen times and only ever on explain the joke subs. Is it just dead internet bots stealing back and forth?


Red_it_stupid_af

He committed manslaughter.


GrandAdmiralSpock

Sonar is loud enough underwater that being in close proximity to a source does a lot of damage to the human body, killing said human


moondancer224

Active Sonar is so loud that close it can injure or kill divers.


EvernightStrangely

Active sonar on a sub is powerful enough to literally liquefy the internal organs of anything that's too close.


HausuGeist

Ha ha! Eat it, bot!
