It measures otoacoustic emissions, or OAEs. These are sounds given off by the inner ear when responding to a sound. There are hair cells in the inner ear that respond to sound by vibrating. The vibration produces a very quiet sound that echoes back into the middle ear.

WebMar 14, 2011 · An otoacoustic emission (OAE) is a low-level sound emitted by the cochlea either spontaneously or evoked by an auditory stimulus. Specifically, OAEs provide information related to the function of the outer hair cells (OHC) (Stach, 2003). Over the past 20 years, their use in routine audiological assessments has increased significantly. WebDistortion product otoacoustic emissions (DPOAEs) are evoked by the simultaneous presentation of two pure-tones or primaries, referred to as f1 and f2. Because the cochlea is non-linear in nature, distortion occurs at various places along the cochlea during stimulus presentation. During a DPOAE test, various pairs of the stimuli are presented ...
