BAER is an acronym for Brainstem Auditory Evoked Response and it is test measures of ear and brain wave activity that happens in reaction to clicks or certain pitch. There are 3 waves (1, 3 and 5) set for the ear, BAER uses a computer that averages over time to determine background noise to produce an averaged reaction of the auditory gateway to an auditory stimuli.

It is also useful in conditions where an auditory neuropathy is suspected. In this condition it may be united with otoacoustic emission testing.
