An ABI is similar to a cochlear implant, except the electrodes are implanted directly in the base of the brain. ABIs are used when a person has NF type 2 (neurofibromatosis type 2) and have to have their auditory nerves cut (which renders them useless as far as cochlear implants are concerned). People with ABIs […]
Auditory Brainstem Response Testing (ABR)
A test that can be used to assess auditory function in infants and young children using electrodes on the head to record electrical activity from the auditory (hearing) nerve. More technically, a hearing test that measures the neurological responses of the auditory nerve and brainstem to a series of clicking sounds. Basically, it measures the […]
Auditory Gain
