Abstract

Recently, Withnell and Yates [J. Acoust. Soc. Am. 104, 344-349 (1998)] reported a pure tone acoustic enhancement of the transient-evoked otoacoustic emission (TEOAE). They state that their data conflict with the existing theory that the TEOAE represents a one-to-one frequency response to stimulus component frequencies. Therefore, they interpreted the observed enhancement as a result of a complex interaction on the basilar membrane of hypothetical intermodulation distortion products. This letter reviews recent data and proposes an alternative interpretation that the enhancement results from an impedance discontinuity at the pure tone characteristic frequency (CF) location. TEOAEs at frequencies below this tone are reflected from its CF location rather than from their own CF locations.
