A newborn infant undergoes a hearing screening. Universal neonatal hearing screening ( UNHS ), which is part of early hearing detection and intervention ( EHDI) programmes, refer to those services aimed at screening hearing of all newborns, regardless of the presence of a risk factor for hearing loss.
