New Born Hearing Test ( OAE )

What Is an OAE Test?

An Otoacoustic Emissions (OAE) test is a non-invasive hearing screening that checks how well your inner ear (specifically, the cochlea) is functioning. It is often used for newborns, infants, and individuals who cannot respond to traditional hearing tests.

How It Works

• Inside the cochlea are outer hair cells that respond to sound.

• When these cells work normally, they produce tiny sound waves (otoacoustic emissions).

• The OAE device sends soft sounds into the ear and measures the echo (the emission) coming back.

• If no emissions are detected, it might indicate:

  • Hearing loss

  • Blockage (like earwax or fluid)

  • Cochlear damage

Who Gets This Test?

• Newborns (part of standard newborn screening in many countries)

• Young children

• People with developmental delays or who are non-verbal

• Anyone needing objective hearing assessment

What Happens During the Test?

1. A small probe with a microphone and speaker is placed in the ear canal.

2. The test is done in a quiet room or while the child is asleep.

3. The test usually takes a few minutes per ear.

4. It’s painless and quick—no active participation needed.

   
   

What Do Results Mean?

• "Pass": Emissions are present → Normal cochlear (inner ear) function.

• "Refer" or "Fail": No emissions detected → Needs further testing to confirm hearing loss.

A failed OAE does not necessarily mean permanent hearing loss—fluid in the ear, earwax, or noise during testing can affect results.
