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.
