Otoacoustic Emission Testing (OAE)

Hearing Health text on green background

The otoacoustic emission test (OAE) measures hair cell function in the inner ear. An emission refers to the sound generated within the normal cochlea of the ear in response to stimulation.

OAE testing is used for a number of reasons, including screening of infants and other special populations.

OAE Test: What Happens

The OAE test is noninvasive and requires a small probe to be inserted in the ear. A series of tones or clicking sounds are presented to the patient. The test takes place in a small sound booth, where the patient is required to be still and quiet throughout testing. It takes approximately 30 minutes for the test, after which the audiologist will share your test results with you.
