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...
