Why doesn’t anyone just start blasting music underwater at all times. Wouldn’t this mask any underwater activity you wanted to conduct. I’m the first person to think of this and I didn’t even know about underwater sounds being detectable until yesterday.
Probably because it would be super obvious and you would get environmentalists up your ass for harming underwater life with your eurobeats.
>when you realize environmentalists that care about the oceans being silent are glowies
This, every foundation that is involved with pushing enviromentalism also invest in China which is notorious for causing enviromental damage.
>you would get environmentalists up your ass
We're going toe to toe with a powerful nuclear state. You think we can't drop a couple of pasty-faced environmentalists along the way?
Environmentalists are the only reason you're not in a smog filled china style city anon, dehumanising people that give a shit about the place they live in is pretty shit even if you view groups of them as hypocritical and foreign state funded.
I wouldn't choose music specifically because it would be easier to filter the noise signal out if you have a copy of the noise yourself. Maybe play back false positive sounds of every sort of underwater event possible to make trying to pick out the real ones impossible.
Wow you just invented sonic buoys
I was at the olympic pool today for a swim and they had this exact speaker for a synchronized swimming class. Kinda neat synchronicity.
The sounds would come from your decoy and any listeners would just tune it out.
It might be practical as an anti-torpedo decoy though and who knows, maybe they do this.
>maybe they do this.
They do. The same way airplanes drop flares to try and confuse heat-seeking missiles or chaff to confuse radar there are sonic countermeasures designed to confuse acoustic homing torpedoes.
damn bro did you just invent spoofing?
music can be filtered easily, if anything it has to be fake noises that seem realistic
What about the sound of a wrench dropping inside of a cylindrical railway car
As much as I know underwater warfare (from the game Cold Water) best you can hope is to create a decoy that imitate what you want to hide, and not to high volume or the sound refract on what you wanted to hide, putting it on display.
>We've located the enemy sub
>How can you tell?
>Well at first, I thought they were the loud box blasting 'alabama Black person' loud enough to deafen half their crew, but then I noticed the sound was also rebounding off the side of a much larger object nearby, which clearly deposited the box to try and throw us off
>So what should our next course of action be?
>Tune out Johnny rebel, get a fix on their boat and deploy torpedoes
Tether a 40 foot cylindrical tube a few miles away from the source to simulate a sub.

Sweden does this, plays some pro homosexual message underwater to own putin because of the 2013 Duma vote prohibiting pro homosexual programming for kids... Poor fish
sub can shoot live "decoy" torps to confuse other subs, as well as deploy various decoys (usually anti-torp though)
They sorta do, subs can use counter measures in torpedo evasion, surface ships can also "masker" just putting out a ton of noise in the water column but as said before you still know there's something producing that noise.
You also have to take in consider ambient noise, your own noise. There's a whole bunch of equations and power summinations to figure this out that I don't have the care to do so.
Ambient noise in the environment is a huge deal for sonar and subs thou.
Hope that answers your question OP
ITT submarine Sonar Tech
Also think of sonar decoys more like the chaff or flares on a jet just in this case a submarine.
Please don't. Thanks.

>I’m the first person to think of this
I've been to resorts that were pumping music into the pools in the '90s. Color me shocked that a post with an iFilename is absolutely fricking moronic.
Nah man it needs to be the most fricking brutal BRAAAAAAAP compiliation you can find.
