Otoacoustic emission (OAE) testing and automated ABR (Auditory brainstem responses) are the commonly employed tests for newborn hearing screening. These are simple, quick, non-invasive tests taking about 30 seconds to 30 minutes, depending upon whether a baby is sleeping soundly or moving about. If a baby has any high risk factors present, an automated ABR should be done alongwith OAE. If a baby is from a well-baby nursery then only an OAE would suffice for initial screening.
