Gregory's ServerRecent studies suggest that damage is caused when energy waves surging through the brain bounce off tissue boundaries like an echo, and for a few fractions of a millisecond, create a vacuum that causes nearby liquid in the brain to explode into bubbles of vapor. Those tiny explosions are violent enough to blow brain cells apart in a process known as cavitation.

The first two lines of the Wikipedia article on cavitation: Cavitation in fluid mechanics and engineering normally refers to the phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate shock waves that may damage machinery.  @MarvClowder @deliverator @clive and now.realize.that the strongest sonars can make water boil around them on full blast and that a lethal noise level is possible for literal miles... And whilst friendly submarines should.cease using sonar whilst divers are out, SEALs usually don't tend to be get deployed in friendly waters... ^  @rustoleumlove @MarvClowder @deliverator @clive basically samenreason you can see bubbles in an ultrasonic cleaner... Now imagine this happening within someone's brain... - There's a reason one doesn't put an,ultrasonic on a human head (even if there wasn't a skull making it pointless to try amd see shit)... |
@MarvClowder @deliverator @clive that's literally brain damages by #Sonar with cavitational bubbles and shit temporarily forming beyond the threshhold that makes one nauseous, incapacitates or kills a person...
This seems rather expectable...
