ABR or Auditory Brainstem Response is a reliable hearing test that is significantly different from traditional auditory tests. The ABR tests are particularly useful for new born babies, young adults, or elders who do not have the ability to communicate their responses during the test. The hearing test is also effective for a patient who has encountered a head injury and is unable to respond adequately.
In the ABR test, the child or adult does not have to respond to sounds. In addition, they need not be awake while the test is being performed, with new born babies typically given an anesthetic so that they stay relaxed while the test is being conducted.
The ABR is a very safe test – no discomfort will be faced by the patient during the entire process. The entire test is done within 2 hours and the patient can get back to their normal routine immediately after.
