Otoacoustic emissions (OAEs) are sounds produced by the inner ear in response to a sound stimulation. It is like an “echo” coming from the hair cell vibrations of the inner ear when sound is detected. The otoacoustic emissions can be measured using a small probe inserted into the ear canal. The purpose of OAE measurements is to determine the funtion of the cochlea, particularly the hair cells. Those with hearing loss typically do not produce otoacoustic emissions because their cochlear structures no longer function normally.
