A baby’s hearing can be screened using Automated Auditory Brainstem Response (AABR), Otoacoustic Emissions (OAE), or both. Babies usually have their hearing screened while still in the hospital, either in the nursery or in their mothers’ room.
How do I know if my baby has hearing problems?

How do you test an infant’s hearing?
Sounds are played to the baby’s ears and band-aid like electrodes are placed on the baby’s head to detect responses. Sounds are presented to the ears using small earphones. The electrodes pick up responses from the hearing nerve and a computer measures the responses to identify babies who have a hearing loss.
When should a baby’s hearing first be tested?
It’s best to have your baby screened before they are 1 month old. Hearing screening can be done quickly while your baby sleeps or is quiet. Younger babies spend a lot of time sleeping, so it’s easiest to screen hearing in babies who are very young.

How can I test my child’s hearing at home?

How accurate are hearing tests on newborns?
