I assume your reference to non-linearity was from my questions. The
non-linearity I am refering to is in the mathematical sense. In a linear system
only harmonically related partials will be produced (i.e. interger multiples of
the fundamental). When multiple tones are present these can combine (because
of a non-linear element) but will still only produce integer multiples and sums
and difference of the tones involved. The resulting tones that propagate will
be determined by the filtering of the system (the Q as mentioned in Jon C.'s
message). I'm not sure how the partials would become non-harmonically related
(i.e. non-integer multiples of the fundamental). This would require a
non-linearity in the system that I don't understand, even with the presence of
a noise source. I am very curious about this and would like to be able to
discuss this with anyone that does understand the physics of this phenomenom.
Maybe off-line since this is definitely going to bore a few people. Sorry for
the more technical
posting, but this is a VERY interesting problem and the technical discussion
needs to be more accurate to understand it. I have also run this problem by
several colleagues and all are baffled.
