In Reply to: Piezo sensitivity of speaker wires... posted by jneutron on January 9, 2004 at 12:07:45:
I took a look at the site and the results, and it brings up some questions. First, one about the stimulus:A section of each coax was looped into a circle of about 6 inches and was flicked with the middle finger.
It wasn't clear how/if the cable was restrained when you flicked it. In other words, was the loop of cable resting against a hard surface, and you flicked the stationary cable? That's what it sounded like, but I wanted to clarify.
It also brought up the question of the estimate of the stimulus magnitude. On the site you said:
A physicist friend 'guestimated' the striking force to be several hundred Gs, but not more than 500.
Do you have any more info about this "guestimate"? How did he arrive at this range?
