But don't confuse Elifritz with reality.

Interesting, you are saying that a feedback mechanism exists that can
equal
or exceed the purturbation that stimulates it.

Buy an electric guitar and a loud amplifier. Plug the guitar into the
amplifier, then turn it on. Crank the volume up to high. While facing the
speaker, play the chord "E" and sustain it until you start getting
feedback. Then tell me if the feeback level exceeds the purturbation
(striking the chord) that stimulats it.
