The Auditory Brain Stem Response  is a helpful tool in determining a child’s ability to hear.

The Auditory Brain Stem Response (ABR) is a test to measure the brain wave activity in response to certain tones and is recorded using electrodes placed on the scalp.

Clinical Procedure

  1. Patient is made to lie on a reclining chair or bed and remain still. It is not necessary for patient to be awake during the test.
  2. Electrodes are placed on the patient’s vertex, earlobes & forehead.
  3. A continuous click or tone will be delivered through earphones.
  4. The attached electrodes pick up brain’s response to these sounds and a computer sums the time-locked responses for the first 10 msec after sound stimulation.
  5. Results are presented in a form of graph.

Patient Prior Preparation

  1. ABR is a risk free test.
  2. Patient may be requested to have a hair wash on previous night of the test.
  3. It is mandatory for babies & children to be asleep during the test. Parents are requested to plan accordingly.
  4. For children above 7 years, the ABR test is usually done when the child is awake. It is important for the child to remain relaxed and lie still while testing.
  5. Incase the patient/child has any special needs or health issues, kindly call our audiology department and notify us in advance.
