The only common thing I can think of in nature that causes actual explosive shockwaves, is lightning. Thunder is about as loud as a gunshot, but nobody is holding it at arms' length on full auto.

 @kkarhan @violetmadder @zl2tod @hannu_ikonen @clive If sonar does that to people, it must be hurting whales too. @kkarhan @zl2tod @hannu_ikonen @clive Firearms are not "normal harsh noise", and earplugs won't protect your brain. The shockwave is a concussive blast that travels through the whole body in an abrupt strike. Sonar is a whole other separate issue.  @violetmadder @zl2tod @hannu_ikonen @clive I disagree since then we'd see the same issue with #Jackhammers and other pneumatic powertools... Ear protection works because you ain't firing the gun in an uncompressable medium (i.e. water)... With sonar the person is encased in an uncompressable medium and thus the energy is undampenable...  @kkarhan |
@violetmadder @zl2tod @hannu_ikonen @clive yes and no.
Cuz OFC there's ear protection and if it was vibrations and just normal harsh noise there would've been sufficient samples before...
I'd still bet it's #Sonar given that even remotely hearing one is considered a "GTFO the water - NOW!" thing in terms of diving because that sonar can turn one's brain into Bolognese Sauce before the sonar operators even realize they're close to a diving spot...
