Auditory Brainstem Response Evaluations (ABR or BAER)

What are the Auditory Brainstem Response Evaluations (ABR or BAER)?

The Auditory Brainstem Response test is used for two purposes:

  • For assessment of hearing thresholds in specific populations
  • To assess the functional status of the auditory neural pathway

What should I expect?

This test is non-invasive and is performed with recording electrodes placed on the forehead and ears. The audiologist will analyze recordings of electric potentials generated by the auditory neural pathway.

This procedure is performed while the patient is lying down in the sound booth. The patient is required to be still and quiet throughout the test; therefore some infants and small children may require sedation. If the patient is a child, there will be need for sedation. See preparing for a pediatric procedure.

How long does the test take?

The test will range from 60-120 minutes.

How will I receive my results?

The audiologist will share your test results with you at the completion of testing.
