Electrophysiological tests allow audiologists to accurately measure the nature and severity of hearing loss for individuals that are otherwise difficult to test conventionally (infants, developmentally delayed children, etc.).
With these tests, we can also assess the function of the auditory nervous system.
The most common of these tests is the Auditory Brainstem Response (ABR) evaluation. Other tests include the AMLR, ALR and the Auditory P300 measures.
