Universal neonatal hearing screening (UNHS), also known as early hearing detection and intervention (EHDI) programs in several countries, refer to those services aimed at the early identification, intervention, and follow-up of infants and young children who are deaf or hard-of-hearing. It is a strategy for early detection of permanent congenital hearing loss. It describes the use of objective testing methods (usually otoacoustic emission (OAE) testing or automated auditory brainstem response (ABR) testing) to screen the hearing of well newborns in a particular target region.
