no not gain. See the August 28 issue of Nature on effects of
viberation in a grandular field producing OSCILLONS. You will notice
that oscillons consist of two phase. An activating phase and an opponent
phase. In neuro processing the opponent-process causes the occurrance of
for example: paralyze 1/2 of the tongue and sugar, sour, and bitter will
double in reported taste. This is equal to tinnitus.

I agree that internal gain is turned up for the unstimulated system. That
is why the opponent wavelet produces tinnitus. Some time ago an
audiologist reported that he hear ringing in his ear when he accidently
press a pair of open sissors against his arm. The wavelet stimulation
caused a harmonic loop of opponent-process resulting in tinnitus.
He had an audiologist check this out and his friend HEARD the sound
coming out of his friends ear. The ear can also be a speaker because
of correlational opponent-processing.

white noise acts as a reference wavelet. The hearning system as all
systems is depend on reference or CARRIER frequencies to interpret events.
A entrainment wave system should do the same thing.
