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.
Auditory Brain Stem Response (ABR) Test: This test is used to evaluate the auditory brain stem (the part of the nerve that carries sound from the ear to the brain) and the brainâs response to sound. During this test, miniature earphones are placed in the ear and sounds are played. Band-Aid-like electrodes are placed along the babyâs head to detect the brainâs response to the sounds. If the babyâs brain does not respond consistently to the sounds, there may be a hearing problem.
