Diagnostic Auditory Brainstem Response (ABR)

ABR testing is a painless procedure that provides information about the inner ear and brain pathways for hearing. To ensure accurate results, infants are required to be asleep or quite during testing. The audiologist will place three to four electrodes on the head and neck of the patient, which will record the brainstem electrical response to sound.

The sounds used will vary from soft to medium to loud, and will depend on the patient’s hearing. The benefit of the ABR is that it can record a response to very soft sounds with varying pitch.

To keep your infant quite and comfortable, please bring a bottle and pacifier and blanket (breaks can be taken for nursing during the appointment if necessary). The appointment will take approximately two hours total.
