Abstract
Otoacoustic emissions(OAEs) are low-level sounds produced by the inner ear. This is based on the discovery that the cochlea in the normal human inner ear itself emits in the form of acoustic energy. Thus we transmit the stimulus to the ear through speaker then measure the evoked response using miniature microphone. Otoacoustic emissions are averaged by time-locking so that distinguish the spectrum between normal human and impaired.
