Spacing of hearing-threshold minima matches the 180-degree phase-shift frequency distance

Evidence

In this context, it is interesting to realize that the most probable frequency distance between neighbouring minima for threshold in quiet or between neighbouring spontaneous emissions, is closely related to the frequency distance needed to shift the phase by 1800 near the CF. The data of Fig. 3.28 at. 1, 1.6, and 2.5 kHz indicate about 70, 110 and 160 Hz, respectively. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 362

• QUESTION: This is a striking numerical correspondence between microstructure of threshold-in-quiet and cochlear phase. Worth chasing how exact the match is across a wider frequency range and what mechanism binds them.
