Re: Noises through pickups (rather gongs...)

I'd love to hear the results of your test!  I fear that you will have
difficulty with just an oscilloscope because of the extraordinarily complex
nature of the bowl's harmonics.  Like a drum or a bell, the bowl will
probably produce hundreds of harmonics, at very odd intervals.  I've been
trying to find a method of determining the fundamental of a bell--looking
for research on the web--but have only come across something that mentions
that it is the lip of the bell that produces the "hum tone" or lowest
fundamental.  If I could figure out the means to translate lip diameter to
fundamental tone, well, we'd have our answer.  If that fundamental was
higher than what we hear as the lowest component, then we'd know if it was
a psychoacoustic effect.  If not, then I'll eat crow.
