When Is an ABR Hearing Test Necessary?
For Newborn Hearing Screening, an Auditory Brainstem Response Test is usually performed as a follow-up test of an OAE hearing test (Otoacoustic Emissions test). While an OAE hearing test can only confirm hearing function up to the cochlea, the ABR screening is a more advanced hearing test to evaluate the processing of an acoustic stimulus by the auditory brainstem. ABR tests can be performed with persons of all ages. They are very often used in Newborn Hearing Screening, as they do not require an active response from the patient and can objectively locate postcochlear lesions affecting the hearing.
