Our Hearing Unit offers Otoacoustic Emissions Test, which is used to find out how well your inner ear works by measuring otoacoustic emissions or OAEs. These are sounds given off by the inner ear when responding to a sound. There are hair cells in the inner ear that respond to sound by vibrating. The vibration produces a very quiet sound that echoes back into the middle ear. This sound is the OAE that is measured.


How the Test is Done

A tiny probe is placed just inside the newborn’s ear canal. It measures the response (echo) when clicks or tones are played into the baby’s ears.


Interpreting Results

If a baby hears normally, an echo is reflected back into the ear canal and is measured by the microphone When a baby has a hearing loss, no echo or a reduced echo can be measured on the OAE test.


Why an OAE Test is Important

Undiagnosed hearing loss can cause disorders in speech and language and delay in social and emotional development. An OAE test is an important part of the newborn screening process for early detection and prevention of permanent hearing loss.
