This phenomena (was) is known as diplacusis. 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 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.
