Dear Jan, Leon, and Andrew,
G. van den Brink wrote several articles on binaural diplacusis. He
cites many of his earlier studies in this JASA paper:
van den Brink, G. (1971). Two Experiments on Pitch Perception. The
Journal of the Acoustical Society of America, 49(1A), 74-75,
doi:http://dx.doi.org/10.1121/1.1975957.
Good luck,
-Pierre

Dear Jan,

Dear List,
I have had a conversation with a musically keen
retired physicist who assured me that when he holds up
a tuning fork to one ear he hears the pitch of the
tuning fork about a semitone lower than at the other
ear. I had to say that I found that surprising. We
always assume that there has to be a good alignment of
frequency channels going into the binaural centers of
the brainstem for example, and much effort is invested
in trying to improve "inter-aural pitch matching" for
cochlear implant patients. But I have to admit I know
of no formal studies that have actually measured how
good inter-aural pitch matching would be for normally
hearing subjects, and whether a difference of a
semitone (after all, only a few % in absolute terms)
is absurdly large or within the expected human
variability. Would any of you know of any papers that
have looked at this?
Best,
Jan
