The response of neonates to intra-uterine sounds.
Playing prerecorded intra-uterine sounds to newborns reportedly soothes the babies. This study investigates this claim, particularly because of its promise for identifying neonates with severe hearing losses. 60 babies, up to eight days old, were observed individually under two conditions. In one, activity was rated on the Brazelton scale before and during presentation of intra-uterine sounds. In another, similar ratings were made but no sounds presented. The results indicate that intra-uterine sounds calm 90 per cent of babies who are fussy or crying but have no evident effect on babies who are awake but merely alert or who are slightly drowsy. These findings are discussed and improvements in procedure are suggested for use of intra-uterine sounds in routine screening for severe neonatal hearing loss.
