[NewCandle] Nick's voices in the head

[Nick Reiter]

Heyyo,

I recall trying several other types and sizes of
piezos, though at the time I had none other that was
larger.  Never got much with anything but those discs
from Cleveland.

I would think that if whatever transducer you have is
resonant at some lower frequency and antiresonant at a
higher one, whatever that antiresonant point is, ought
to do the same trick.  Try it down low on your leg
too.  For some reason, I remember it worked on the
legs well.
