Abstract

Otoacoustic emissions evoked by low‐level pure tones (stimulus frequency otoacoustic emissions or SFOAE) and brief tone pips (transient‐evoked otoacoustic emissions or TEOAE) were compared within each of three species: human, chinchilla and mouse, using the same methods. In each species the spectrum of TEOAE and SFOAE showed similar fine structure in level and phase versus frequency with nearly identical slopes, indicating comparable group delays. Emission delays were longest in humans and shortest in mice.
