Otoacoustic Emissions (OAE) testing uses a microphone and earphone to calculate an infant’s hearing abilities by measuring the reflection of a sound’s echo as it passes through the ear canal. Otoacoustic emissions are the sounds given off by the inner ear when stimulated by sound. This test is used to determine if there is damage to the hair cells that line the cochlea. Since the emissions are nearly inaudible, a small plug is placed into the ear in order to detect the ear’s reaction to a series of clicks. This test is objective, making it is a useful addition to newborn hearing screenings.
