Abstract

Otoacoustic emissions (OAEs) evoked by pure tones lock onto the phase of the stimulus at the place of their generation in the cochlea. The effects of phase transitions in a pure tone stimulus on OAEs have not been investigated. By combining responses to pure tones with smooth phase transitions, phase-evoked residual responses (PERRs) were extracted from nine normal-hearing subjects. Five of them had PERRs in at least 18 of 36 parameter conditions expected to yield a response. PERRs do not have a straightforward dependence on stimulus parameters, but their general prevalence suggests a temporary decoupling between stimulus and OAE phase-between 5 and 10 ms. Since the stimulus is narrow in the frequency domain, the PERR may reflect the dynamic behavior of localized regions of OAE generators.
