FWIW, I recently suffered some inner-ear damage due to a virus ?
specialists don't definitively know yet. At 1st I was completely deaf
in the left ear. Gradually the sound is coming back. I now get the
following properties in my perception of sound :-
Low freqs(<1000Hz) + High freqs(>3KHz) are ok ( well, as good as they
ever were)
Mostly silence from 1KHz -> 2.2KHz, but strong peaks of response at a
few spot frequencies.
The weidest thing is hearing the same pure sinewave a different
frequencies depending on whether I use the right ear or left ear. The
difference is like C to F# in the same octave.
The above figures are not exact, but are roughly what I get.
I had always imagined that perception of frequency would be invarient
from left to right ear, but now I know better.
