During the test , your child will sit on your lap or a chair while sounds are presented. Your baby will be taught to link the sound to a visual reward such as a toy or computer screen lighting up.

An ABR test usually takes 1–hours, but the appointment may last about hours. If a sleeping baby wakes up during the test , the test will take longer because the baby will need to fall back asleep again to finish the test.

This test is similar to the ABR , though an infant usually needs to be sleeping or sedated for the ASSR test. Sound passes into the ear canals, and a computer picks up the brain's response to the sound and automatically decides whether hearing loss is mil moderate, severe, or profound.

An analysis of the activity in the brain reveals the thresholds of hearing.

ABR can also be used as a screening test in newborn hearing screening programs. A screening is a test where you either pass or fail. The baby passes if his brain shows that it is hearing the sound. If the baby fails the test , more specific testing will be done. The hearing tests for toddlers include the behavioral test , visual reinforcement audiometry (VRA), conditioned play audiometry (CPA), pure tone audiometry, tympanometry, and auditory brainstem response test.

In the behavioral test , the child’s behavioral response to sounds such as pure tones and calibrated speech is observed. Fauquier ENT 173views. Weber and Rinne Test - Clinical Examination - Duration: 8:37. AMBOSS: Medical Knowledge Distilled.
