• The Correlation between Psychophysical Tuning Curves and Distortion Product Otoacoustic Emissions.

抄録

We examined psychophysical tuning curves (PTC) and distortion product otoacoustic emissions (DPOAE) in the normal ears and discussed the relation between these two phenomena. The stimulus levels of f₁ and f₂ in DPOAEs measurement were set so as to make those geometric means (GM) 1, 2 or 4kHz. The sound pressure level of f₂ was less than that of f₁ by 10dB and the ratio of f₂/f₁ was 1.2. Simultaneous PTC was obtained by determing the minimum level of a pure tone masker to mask the probe tone (0.5, 1, 2, 4kHz) 10dB above the threshold. When f₁ in DPOAEs was regarded to be equivalent to that of the probe tone in PTC, the frequency at inflection point of PTC where “tip” meets “tail” was coincident to that of DPOAEs at the corresponding frequency. Considering that DPOAEs relate to the active process of the cochlea, the coincidence of DPOAE and PTC is considered to be a phenomenon indicating that both of them closely relate to the frequency selectivity of hearing.
