Newborns & Infants
A baby's hearing screening is tested using Otoacoustic Emissions (OAEs). For this test, a miniature earphone and microphone are placed in the ear. Sounds are played in the ear and a response is measured. If a baby hears normally, an echo is reflected back into the ear canal and is measured by the microphone.

Woman's Center for Wellness uses a combination method of both pure-tone and speech testing for hearing screenings. A pure-tone test determines the faintest noises a person can hear at various frequency levels from high to low. Headphones are worn during this test so that each ear can be tested individually. Speech testing is used to confirm pure-tone testing results and it determines the quietest level at which a person can understand words.
