Early diagnosis of hearing loss is crucial for timely intervention. Two primary screening tests are used:
Otoacoustic Emissions (OAE): This test measures sound waves produced in the inner ear. A small probe is placed in the ear canal to detect these emissions. Auditory Brainstem Response (ABR): This test measures the brain's response to sound. Electrodes are placed on the baby's head to monitor brain activity in response to auditory stimuli.
