Auditory Brainstem Response Evaluations (ABR)
What is an ABR?
Auditory Brainstem Response Testing, also known as ABR Test, is a method of measuring how well
the auditory system functions. The test requires no participation from the patient, allowing the
test to be completed on patients as young as 2 weeks old. To complete the ABR, the audiologist
places earbuds in the patient’s ears and small stickers called electrodes on the forehead and
behind the ears. The audiologist then measures the patient’s brain activity in response to
low-level clicking sounds played through the earbuds.
