内耳モデルと耳音響放射

抄録

A nonlinear transmission-line-analog model of the cochlea, which is a version of the onedimentional long-wave model of the cochlea, was used to simulate evoked otoacoustic emissions (EOAEs). The model produced echoes very similar to real EOAEs in respect to the latency, spectral features and saturation characteristics when highly damped points were set on the basilar membrane (BM) with equal spacing. It was concluded that EOAEs were the waves reflected from BM due to irregularities of the impedance.
