Otoacoustic emission test: a type of hearing test that measures an acoustic response produced by the inner ear (cochlea), which in essence bounces back out of the ear in response to a sound stimulus.

 

The test is performed by placing a small probe that contains a microphone and speaker into the patient’s ear. Sounds are generated in the probe and responses that come back from the cochlea are recorded. Once the cochlea processes the sound, an electrical stimulus is sent to the brainstem. In addition, there is a second and separate sound that does not travel up the nerve but comes back out into the ear canal. This “byproduct” is the otoacoustic emission test result. The emission is then recorded with the microphone probe and represented pictorially on a computer screen. The audiologist can determine which sounds yielded a response/emission and the strength of those responses. The test is used in a number of different ways to test hearing.

The primary purpose of otoacoustic emission (OAE) tests is to determine cochlear status, specifically hair cell function. This information can be used to

(1) screen hearing (particularly in neonates, infants, or individuals with developmental disabilities), (2) partially estimate hearing sensitivity within a limited range, (3) differentiate between the sensory and neural components of sensorineural hearing loss, and (4) test for functional (feigned) hearing loss. The information can be obtained from patients who are sleeping or even comatose because no behavioral response is required.

The normal cochlea does not just receive sound; it also produces low-intensity sounds called otoacoustic emission test in children OAEs. These sounds are produced specifically by the cochlea and, most probably, by the cochlear outer hair cells as they expand and contract
