BAER or Brainstem Auditory Evoked Response

What is a BAER?

The brainstem auditory evoked response (BAER) test measures responses in brain waves that are stimulated by a clicking sound to evaluate the central auditory pathways of the brainstem.

You will be positioned on a reclining chair or bed and asked to relax and remain still. Electrodes will be placed on your scalp and on each earlobe. You will hear clicking noises or tone bursts through earphones, and the electrodes pick up the brain's response and record it on a graph.

How to prepare for the test:

Please wash your hair the night before the test.

How will the test feel?

There is little discomfort.

Why is the test is performed?

The test is performed to help diagnose nervous system abnormalities, hearing losses, and to assess neurologic functions.
