Comment by Keefe:
------------------------------------------------------------
The Keefe and Burns (1992) reference establishes that subjects
can detect an intermittent SOAE just as they can detect a low-level
intermittent tone.  It was concluded that short term adaptation effects
well known for the perception of external tones also apply to perception
of intermittent SOAEs.  In another set of measurements, the subject can
pitch match to a linked SOAE in which one of the SOAE components changed
in frequency by a musical interval of 78 cents.   The rapid fluctuation
in pitch was observed in the associated short-time Fourier transform of
the SOAE components.  The conclusion that this type of tinnitus has a
cochlear-based origin in the SOAEs follows from these observations.  The
existence of linked SOAEs is consistent with a traveling wave description
of SOAE generation, as spatially distinct sites are mechanically linked.
This type of linkage is described more in one referenced paper (Keefe et
al. (1990)).  This latter reference established that linked SOAEs had a
common phase-locking frequency consistent with a common dynamical origin.

The adult subject of Keefe and Burns (1992) was Ed Burns.  I wish he would
publish his longitudinal measurements of SOAE frequencies and levels
in a number of individuals, which extend over more than two decades.
Many SOAEs are inordinately stable over time.

There's been a number of posts on tinnitus and SOAEs.  Tinnitus is
multi-dimensional in its effects.  In many people with otherwise normal
hearing, tinnitus is occasionally detected as an intermittent low-level
tone.  Such tinnitus in some cases can be explained as produced by
SOAEs.  In one case study reported in

Burns, E. M., D. H. Keefe (1992).  Intermittent tinnitus resulting from
unstable otoacoustic emissions, in "Proceedings of the IV International
Tinnitus Seminar", eds. J.-M. Aran and R. Dauman (Kugler, Amsterdam),

Ed Burns had the idea to test whether the intermittent sensation of
tinnitus was correlated with the presence of an intermittent SOAE.

A subject sat in a sound attenuated booth and pressed a button whenever he
heard the tinnitus.  The subject depressed the button as long as he
continued to hear the tinnitus.  After some period of time, on the order
of several 10's of seconds, the sensation of tinnitus disappeared. 
Simultaneously, the lab computer made continuous measurements of SOAE
spectra with emphasis on a particular frequency component that appeared
and disappeared (relative to the noise floor) in the subject's ear. 

What happened was that the onset of the SOAE signal produced the onset
of tinnitus--as quantified by the subject depressing the button.  The
subject tended to release the button before the SOAE disappeared, which
was interpreted as a short-term adaption to a low-level tone.  The SOAE
level tended to decay back into the noise in an intermittent fashion,
but everytime it re-appeared, the subject would again have the sensation
of tinnitus and depress the button.  The subject had other
non-intermittent SOAEs that were inaudible as tinnitus, which suggests
that SOAEs are not perceived as tinnitus due to short term adaptation,
but intermittent SOAEs may be audible as tinnitus until short-term
adaption wins out.  The subject was unaware of the results of the SOAE
measurements.  Not having the article handy I believe the spectrum was a
64k-sample FFT or so at a 22.05 kHz sample rate, and I don't recall if
we interleaved FFTs.
