In addition to these, there are also behavioral audiometry tests, which are used typically for older infants and toddlers. These tests are used to observe the baby’s response to sounds, such as turning the head or eye movements.

Explanation of the Tools Used

Delve into the world of baby hearing tests as we demystify the intricate array of tools utilized in this essential assessment. Comprehending tool purpose boosts parental confidence, enhances exam understanding, and nurtures a holistic view of auditory health.

Otoacoustic Emissions (OAE)

This is a test that measures the echo or the sound that the ear produces in response to a sound stimulus. A healthy baby’s ear makes a sound when stimulated; the cochlea produces sound echoing back in normal hearing. This sound can be measured with a tiny microphone placed in the ear. If no sound reflects back, it could indicate a hearing loss.

Auditory Brainstem Response (ABR) Test

ABR tests the way the auditory nerve and brainstem respond to sound. It’s particularly useful because it doesn’t rely on a behavioral response. During this test, small electrodes are placed on the baby’s head to pick up responses as the baby is exposed to sounds. These responses are then plotted on a graph and interpreted by an audiologist. This test can give information about the softest level of sound the baby can hear.
