Otoacoustic Emissions

North Valley Hearing Center, LLC is equipped to provide Otoacustic Emissions (OAE) testing. OAE testing enables the audiologist to test infants, toddlers and other individuals with questionable pure tone results.

A small probe that contains a microphone and speaker is placed into the patient’s ear canal, and sounds are presented. If there is an emission present for those sounds that are critical to speech comprehension, then the patient has "passed." This test cannot measure how much hearing loss is present; but it can tell if the cochlea is responding normally or not.
