10 Mind-Boggling Facts on Unraveling the Mystery of Pulsatile Tinnitus

3. Brainstem Auditory Evoked Response

A brainstem auditory evoked response test, more commonly called a BAER test, is a diagnostic tool that measures how well a patient's brain processes sounds. This can help determine whether the cause of pulsatile tinnitus is in the ear itself or neurologically-based. BAER tests record the feedback of the patient's brainwaves when they're exposed to certain audio tones or a series of clicks. The test helps determine the cause and severity of hearing loss in multiple different cases. It also helps diagnose nervous system issues that lead to auditory processing problems. BAER tests are most frequently used with young children, newborns, and individuals unable to partake in standard hearing tests.
