The point I was trying to make is that there is only ONE way for a system
to be linear, and nearly INFINITE ways for it to be NON-linear. In any
case, if a difference tone can be generated that makes physical objects
shake, including eardrums, microphone diaphragms, walls, etc., I just have
to believe that it exists in space beyond my own head.
