About the same.
It's cool though. The navy says they don't mind.
And people wonder why whales beach themselves.
I thought that was because of the windmills?
Yeah. I had presumed the sonar was just annoying, not body destroying.
Well…I imagine they kind of disappear into a mist
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
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.

Yes. But in the same way being hit by a train causes hearing loss.
200+ decibel pressure wave.
So about half the volume of my upstairs neighbours
...at 4am on a Wednesday
Minotaurs?
So is that how it went? How have things gone in the ten years since this article was written?
We've been heating up the oceans so all the marine life will die and not have to worry about sonar anymore.
That's one of the symptoms, yes.
ded
Yes, we won't be hearing from them again.
