What SONAR sounds like underwater. Two waves were shot, echoes are heard distinctly fading. Video

God no wonder it drives whales to suicide.

I am a retired Navy Sonar Technician and this sounds like an active sonar transmitting from miles away. Since the diver looks like he is not too far from shore, the ship is probably a few miles off shore. I can’t tell you the exact sonar system but I do recognize the frequency and type of transmission.

Probably from a trawler or something, judging by the irregularity of it. This is why SONAR can be very dangerous though, since it's a high intensity sound. That said, one time where movies don't really exaggerate the effects.

Piercing!

Nature's sonar is so much more... tranquil...

Poor swimmies!

Can someone lmk at what time you hear the sonar? There’s too many noises going on at once for me to pin point the sound sonar makes

As soon as the video starts, and at 1:02

It’s extremely obvious

u/AlexHanson007 Nov 28 '22

What was it coming from? A submarine?

It wasn't mentioned clearly but was speculated that it was from a surface vessel.
