Automated Auditory Brainstem Response (AABR) is used primarily for newborn hearing screening. This type of ABR is automatically analyzed and designed to generate a pass or refer result. Traditional Auditory Brainstem Response (ABR) testing consists of not only ABR testing, but a battery of other evaluations to diagnose hearing loss or other ear disorders. ABR testing is performed by an audiologist, who interprets the results manually and helps develop a treatment plan for the patient.
