BERA (Brainstem Evoked Response Audiometry), also called ABR, measures the brain’s response to clicking sounds played through earphones. Because the patient does not need to respond, it is ideal for testing hearing in newborns, young children and adults who cannot do a regular hearing test.
Why it is done
- Hearing screening in newborns and infants, especially high-risk babies
- Delayed speech in children
- One-sided hearing loss or tinnitus in adults
- Evaluation of acoustic neuroma and other auditory nerve problems
- Medico-legal and disability assessment
Preparation
- Wash hair; no oil.
- Babies and young children must be asleep — keep the child awake before the visit and feed just before the test. Sedation may be advised by the doctor.
Frequently asked questions about BERA
At what age can BERA be done?
