Killing with sound   I have removed the following paragraph because it seems not based on any scientific facts and sounds very implausible A loud cry directly to the ear might permanently damage hearing but seriously damage ones organs Considering that even the whole hydrophonic shock stuff by supersonic ammo was found to be exaggerated I simply cant leave this unchanged  tiktak    There are also martial artists who can use kiai as a weapon  The sound waves of your voice go straight through someones body  Since the human body is almost completely made out of water and since sound waves easily go through   waterlike electricity goes through wateryou can seriously damage ones organs with this technique
