Input/output Functions of Transient-Evoked Otoacoustic Emission Measured Using Nonlinear Extraction Method

Original language description

Otoacoustic emissions are generated by two fundamental mechanisms: nonlinear distortion and linear reflection. Abdala and Kalluri suggested combining information from two different types of otoacoustic emissions (OAEs), each generated by a different mechanism, to "characterize sensory hearing loss most effectively". They used stimulus-frequency OAE (SFOAE) generated mainly by linear reflection from irregularities, and distortion-product OAE (DPOAE) whose primary source is nonlinear distortion. Transient-evoked OAE (TEOAE) is another type of reflection source OAEs and we aim to investigate whether this type of OAE could be used in the joint OAE profile instead of SFOAEs. We employed a nonlinear cochlear model to compare I/O functions of click-evoked OAEs (CEOAEs) simulated with the linear extraction method, which requires the use of a suitable window to remove the evoking click, and nonlinear extraction method, which removes the click by subtracting the click response from the scaled response evoked with a click of higher intensity. Despite the fact that the nonlinear method removes everything that grows linearly, the amplitude of simulated CEOAE I/O functions saturated at roughly the same stimulus levels for compressors 6 and 9.54 dB above the probe level. The amplitude fine structure and phase slope of CEOAEs were qualitatively equivalent for both extraction methods. We found qualitatively similar results in measured CEOAEs.
