Subj: [kl] Pitch difference between ears
Date: Tue, 1 Oct 2002 09:00:26 -0400

A friend of mine, a 'cellist, is having trouble because she's begun to
hear sharper in one ear than the other. I searched on the web, and
found that it's a known phenomenon called Diplacusis.

In fact, I have a slight difference in pitch perception: my left ear
perceives just slightly sharper than my right. But hers is more marked,
being more than a quarter tone.

Does anyone else experience this, or know anything in detail about it?
I do know that according to one theory of pitch perception, the pattern
matching theory, we perceive pitch by doing a 'best fit' of the various
components of a complex oscillation to a harmonic template, the
fundamental of which becomes the perceived pitch; so one might imagine
that loss of sensitivity to higher frequencies in one ear, say, could
account for a part of the problem.

But she -- and I -- would be grateful for any information.
