BERA (brainstem evoked response audiometry, also called ABR) measures the hearing nerve and brainstem responding to sound. We clean small spots on your baby's forehead and behind the ears, place soft stickers called electrodes, and play clicks and tones through tiny earphones. A computer records the brain's response.
Because it needs nothing from the child, BERA can estimate the softest sound a baby hears in each ear, and whether the problem is in the ear or the nerve. It is used to confirm a failed screen, for babies at higher risk, and for children who cannot do play tests. It takes longer than OAE, so it works best in deep sleep.
Bring anything that helps your baby settle. If an older child cannot settle, we will talk through the options with you and your child's doctor.
