Cochlear reflectivity has been theoretically estimated for different otoacoustic emission generation mechanisms, using a standard perturbative approach based on the WKB approximation and the osculating parameters technique. The predictions of theoretical models have been compared with experimental measurements of the TEOAE transfer function at different stimulus levels, between 60 and 90 dB pSPL. The phase-gradient delay of the TEOAE response has also been compared to the estimates of the cochlear transmission delay obtained with time-frequency analysis of the same TEOAE waveforms. Place-fixed and wave-fixed OAE generation mechanisms are discussed in the light of the results.

Abstract
Cochlear reflectivity has been theoretically estimated for different otoacoustic emission generation mechanisms, using a standard perturbative approach based on the WKB approximation and the osculating parameters technique. The predictions of theoretical models have been compared with experimental measurements of the TEOAE transfer function at different stimulus levels, between 60 and 90 dB pSPL. The phase-gradient delay of the TEOAE response has also been compared to the estimates of the cochlear transmission delay obtained with time-frequency analysis of the same TEOAE waveforms. Place-fixed and wave-fixed OAE generation mechanisms are discussed in the light of the results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
