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.
In the auditory brain, several groups of neurons receive the impulses and translate them into a language that our brain understands. This translation occurs in order to cause a conscious perception of the sounds that we receive. The Auditory Brain Transformation and processing of sound generally occurs on three levels in the brain: As a reflex, in the auditory cortex and in other brain areas. Thus, the arrival of the message may first of all trigger a reflex and cause us to jump or turn our head.
