Welcome to Newborn Hearing Screening Wales (NBHSW). Our website aims to provide information for parents, professionals and the general public. We welcome your feedback and comments to help us give you the information you need, and to help us keep the website interesting, informative and up to date. One or two babies in every 1000 are born with a hearing loss that may affect their speech and language development. Newborn hearing screening helps to find those babies and offer help and support from the start.
