Fact 6: Using sound as a weapon

Theoretically, it’s possible to be killed by sound pressure, but not in the way you would think. If an explosion is large enough, it can create what’s called blast overpressure, which is the sudden rise in atmospheric pressure that normally follows a huge detonation. This also causes an incredibly loud noise, which you would likely not even hear because your eardrums would have shattered at around 160 decibels. At 200 decibels, the pressure would be enough to rupture a lung and cause other internal injuries. This caused confusion during WWI, when soldiers were found dead despite having no obvious outside injuries. So, the classic movie scene of the hero getting thrown by an fireball, only to get up seconds later with his ears ringing slightly is complete crap. In real life, Rambo would be deaf and dead.
