The relationship between SFOAEs and tuning of cochlear filters in a model of the human cochlea
Popis výsledku v původním jazyce
It has been suggested that the stimulus frequency otoacoustic emissions (SFOAEs) are generated due to coherent reflections of forward-Traveling waves. In this paper, the emissions were simulated by a two-dimensional hydrodynamic cochlea model with parameters based on real dimensions of the human cochlea. Simulations were done using a low-level pure tone at frequencies between 0.5 and 1.3 kHz, and 3 and 6 kHz. In agreement with animal experimental data, the ratio between the simulated SFOAE group delays and group delays estimated from the basilar membrane transfer functions were between 1 and 2. In agreement with the coherent reflection filtering theory, the SFOAE delay was affected by the frequency selectivity of the cochlear filters. However, the simulated results gave different tuning ratios for two models differing only in tuning of their cochlear filters.
