Otoacoustic Emissions


oae test Image

Assesses auditory function through the level of the cochlea. Appropriate from birth through adulthood.

Acoustic emissions generated by the outer hair cells in the cochlea are elicited by direct acoustic stimulation and are recorded by a small microphone placed in the ear canal.

Presence of evoked otoacoustic emissions is correlated with hearing thresholds of 30 dB or better.

Because measurement of emissions relies on reverse transduction of sound through the middle ear, presence of middle ear pathology will preclude recording.
