Fun fact, sperm whales can generate a sonar click at 230dB. Decibels are a logarithmic scale so increasing by only a few dB is basically double the volume.

A sperm whale may swim past you, think you're interesting and give a little click to scan you, and basically stun or kill you instantly.

Wow. For real ???

You learn something new everyday.

But yeah, I never saw divers getting stunned/ killed even when diving near whales.

It could be that it never happened, but that's like such a high variance to have never happened.

i believe it's 6 dB is 2x the sound pressure and 10 dB is 2x the perceived volume?

Is there any example? I've never heard an organism (fish?) killed by whale sound wave like this

[-] Khrux@ttrpg.network 13 points 1 year ago

I couldn't find any report of a death but here is a credible source that it's possible. Sperm whales are particularly rare of course, and intelligent enough to probably know it's deadly, so it's no surprise it's rare.
