It's beyond mine too, not to mention the time spent against the potential
return.

I don't know. All I've seen published is general stuff on vibrational modes
at different frequencies, and talk of more in depth studies with no more
details given, and certainly no formulas. The general consensus seemed to
be that the more data was gathered, the less obvious anything became.
