otoacoustic emissions

otoacoustic emissions
tiny sounds that emerge from the inner ear either spontaneously or shortly after the ear is exposed to an external sound. An objective test of hearing has been developed using otoacoustic emissions. The test equipment creates a small sound and then detects any response from the ear. A normal response suggests that the ear is functioning and that hearing is satisfactory. There are plans to screen all infants in the UK using this technique.

(OAE) subtle sounds produced by amplifying processes in the cochlea during normal hearing and transmitted through the middle ear to the external auditory canal.
