Newborn Hearing Screening Wales (NBHSW) tells us which babies may have a hearing loss. The screening test shows us which babies need more tests to decide if they have a hearing loss.
Screening does not detect all hearing loss or prevent future hearing difficulties.
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.
