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) testing: Electrical nerve impulses that carry the sound from the inner ear to the brain are measured. Electrodes are placed in the ear canal and on the head, and short clicking sounds are turned on.ost people with a sensory hearing loss find that hearing aids are beneficial. Neural hearing loss: occurs when there is damage to the hearing nerve or the nervous system. The inner ear generates neural impulses that travel through the hearing nerve to the brain.
