I know an electrical current sent through or around a crystal will cause the crystal molecules to vibrate, producing ultrasound (above human hearing)
And, that the reverse is true, a mechanical (ie sound) vibration applied to the crystal will produce an electrical field...
my questions are:
1) what magnitude (dB) of infrasonic waves (say, 5 hz to 50 hz) would you need applied directly to a crystal or cluster of quartz crystals, say, as big as an egg...in order to produce a perceptible "static" electrical charge that you could feel if you were holding that "egg"... and let's assume you didn't know the optimum alignment axis, so you are just directing the infrasound through the bottom of the cluster, in the direction of the peaks of the crystals...any ballpark figures?
