You will lie on a reclining chair or bed and remain still. Electrodes are placed on your scalp and on each earlobe. You will wear earphones that give off a brief click or tone. The electrodes pick up the brain’s responses to these sounds and record them. You do not need to be awake for this test.

There is little discomfort.

Why the Test is Performed

The test is done to help diagnose hearing losses, and to assess neurological functions.

Risks
