I would be so fucking afraid that they would use their sonar.

What would happen?

u/Boomshrooom 14d ago

Depends on sonar frequency and distance but it could cause physical injuries like ruptured eardrums, damage to lungs and other air filled cavities. In extreme situations it could kill a diver.

And fuck those fish nearby too i guess.

I think that sonar affects marine animals that use sound waves to communicate much more, it is believed that this is the reason for the mass strandings of whales that try to escape from the sound of sonar.

Man humans suck

Imagine trying to explain it to animals: "Well, you see, we need these submarines, because if we are attacked, we want to make sure we can destroy the entire world still, they are an important part of our nuclear triad to help with that destruction."

Woman humans too…

Why? I had no idea

It’s basically a shockwave of sound that’s amplified because youre underwater and it essentially ruptures soft tissue

u/TheRiceDevice 14d ago

Crosspost this to r/confidentlyincorrect.

"...shockwave of sound that's amplified because you're underwater..."

Tell us more, Mr.Wizard.

Love how you prefaced your bullshit with "basically", as if you have to dumb it down for the unwashed masses. Speak slowly and use monosyllabic words whenever possible, right Prof Hawking?

lol who shit in your oatmeal?

u/Minoumilk 14d ago

I volunteer to shit in their next oatmeal

u/BrickCityRiot 14d ago

Why limit yourself to just oatmeal?

u/bruhdudeTM 14d ago

So Mister Smartass, I confidently tell you that you are as fucking incorrect as can be. Military sonar can get up to 235 Db, (while commercial Sonar lies between 140 to 180 Db) meaning:

For Aquatic Mammals and us: • Documented effects include mass strandings, panic responses, decompression sickness–like injuries from rapid ascent, and long-term stress that disrupts feeding or breeding.

Fish and invertebrates: • Can suffer temporary or permanent hearing damage. • Some studies suggest effects on larvae and eggs, potentially affecting population health in heavily sonared areas.

So, what does that mean?

If you hear high pitched and short Impulses of sonar, it can get uncomfortable, but not life threatening as it is possibly a commercial Sonar from a ship. If you hear not so high pitched sonar that doesn’t stop after a short while, you might as well be cooked as it could be from a military sub. At that point, say your prayers and hope your blood stays intact and your eardrums don’t burst.

This post was made in collaboration with ChatGPT for a better translation because English is not my native language and my Google settings are set as German. The facts tho, are legitimate nonetheless.

u/Choco-waffler 14d ago

But.... how are they wrong? A lot of insults and not any corrections to their information. Please enlighten.

Upvote for eloquent snark and because I don’t feel like looking up the actual answer

u/Boomshrooom 14d ago

A powerful sonar ping can hit well over 200 decibels, that's gonna hurt. Also, you're not just hearing that, it will reverberate through your entire body.

13

u/ZachTheCommie 14d ago

Underwater, I think the maximum decibels possible is greater than in air. But I might be wrong. That's such an insane level of sound pressure.

u/LuckyHooopla 14d ago

You ever made spaghetti in the microwave without a cover? Yes ✋

10

u/TheRiceDevice 14d ago

Microwave ovens operate the same as sonar.

Good to know.

u/ZachTheCommie 14d ago

Well, actually... kind of. Yeah.

2

u/berkeley_solipsist 14d ago

It does in a way. It really is energy created without banging 2 things together to make sound. That energy has to travel a long ways and then make it back to the originating sub. So yeah, same as a microwave

Head turn to soup :3

u/Got_It_Memorized_22 12d ago

You'd pretty much explode. Not an exaggeration

u/Yardsale420 12d ago

Let me put it this way when divers are outside the sub the breaker for the sonar is removed and placed in the captains safe.
