How do they test for hearing loss in babies?

Otoacoustic emissions (OAE) tests whether some parts of the ear respond to sound. During this test, a soft earphone is inserted into your baby’s ear canal. It plays sounds and measures an “echo” response that occurs in ears with normal hearing. If there is no echo, your baby might have hearing loss.
