Almost 40% of population hav= e it. I'm not able to find oldest source, but Bekesy (Experiments in Hearin= g, McGraw-Hill, 1960, page 601) is talking about: "... the "diplacusis" between two finger tips ...is much larger than the diplacusis found in normal ears.". The basic idea why and how it happen is also explained. In German Journal "Hoerger=E4ete Akustik" (now. "Audiologische Akustik") = in early 70-thies a paper was published explaining that this phenomena have = to do with non-musical hearing. It is wrong, while I have difference of almo= st one semi tone, and am able to tune for example a guitar without any reference hearing only left or right (and not pushing a strings to have equal tones). I do not hear any replay (interference) if listening binaurally, and both my thresholds are almost the same. Loudness depende= nt pitch shift was described in JASA (Snow, Vol. 8 (!!), No 1 ) and still actual but not having anything with diplacusis. Zlatan Ribic Dr. Ribic GmbH A.
