[QUOTE="Savant, post: 157734, member: 546108"] I'm sorry, but you are wrong about a few things.. First, Hz is cycles per SECOND.. we'll suppose 60 bpm is accruate, that would still be 1 Hz (one beat per second, 60 seconds in a minute).. at 7Hz it would be 420 bpm and you would die... dB is NOT just a measure of Sound Pressure Level (this I could be mistaken about.. but even if I am, that wouldn't be the only measure of energy of a wave.. as it applies to car audio and what you hear and test it's accurate, but it's not absolute ..) The point being that at (we are guessing but close) ~170 dB there is enough energy for the wave to disrupt the muscle action of your heart.. Keep in mind that "sound waves" pass through things, effecting each thing they touche.. The bass from your speakers don't just hit your back applying "air pressure" and stop there.. if that was the case, you wouldn't hear bass outside your car.. and your doctor wouldn't be able to hear your heart (by the by, the sound from the heart comes from a wave created by full contraction of the muscle, which is NOT the same as the rate it's moving at.. i.e. it's not really 1 Hz of sound, it moves fast enough to create a "sound" more like 50 Hz-ish).. The waves pass through your body depositing energy on stuff as they go.. The theory being that it imparts enough energy against the heart to prevent movement.. Oh, and Microwaves aren't 'radio waves'.. granted, they are all 'waves' but run at different freqs.. And microwaves don't just 'heat water' in things to get them hot, it makes all the molecules move faster (heat is technically moving molecules faster.. slowing them is 'cooling'.. moving them faster is 'heating').. It might have it's greatest effect on water molecules, but I gaurentee you can heat a "perfectly dry" item in a nuker..
