Automated Auditory Brainstem Response (AABR)
This is one of two tests used to screen newborn baby's hearing. AABR is a test used to measure auditory function and threshold of hearing.
Sticky sensors are placed on the baby's forehead and behind each ear. Soft, lightweight heaphones are put over the baby's ears and some clicking sounds are played. The computer records electrical potentials from the nerve of hearing in response to sound.
