Auditory brainstem response (ABR) audiometry is a neurologic test of auditory brainstem function in response to auditory (click) stimuli. First described by Jewett and Williston in 1971, ABR audiometry is the most common application of auditory evoked responses. Test administration and interpretation is typically performed by an audiologist. This article provides an overview of the test and its most common applications.
A brainstem auditory evoked response (BAER) test measures how your brain processes the sounds you hear. The BAER test records your brainwaves in response to clicks or other audio tones that are played for you. The test is also called a brainstem auditory evoked potentials (BAEP) or auditory brainstem response (ABR) test. A BAER test can help to diagnose hearing loss and nervous system disorders, especially in newborns, young children, and others who may not be able to participate in a standard hearing test.
