The newborn hearing screening test is one of the routine checks offered to all babies in the UK in the first few weeks of life, and it is one of the most important. Congenital hearing loss — present from birth or very early in life — affects approximately one to two in every thousand newborns, and identifying it as early as possible makes a significant difference to speech and language development, communication, and educational outcomes.
Understanding what the test involves, how to interpret the results, and what follows if a repeat test is needed helps parents approach it with appropriate context rather than unnecessary anxiety.
Healthbooq supports parents in understanding and tracking routine newborn checks, including the hearing screening, in the first weeks of life.
How the Test Works
The standard first-line test is automated otoacoustic emissions (AOAE). A small probe is placed gently in the baby's ear and plays quiet sounds. The test measures the cochlea's response to these sounds — a normal cochlea produces tiny echo-like sounds in response to stimulation, called otoacoustic emissions. If these emissions are detected at the expected level, the result is "clear". If they are not detected at the expected level, the result is "refer" and a repeat or further test is arranged.
The test works best when the baby is calm and quiet — feeding or sleeping through the test is ideal. It takes only a few minutes and is entirely painless. Babies who have fluid in the outer ear canal from delivery, or who are unsettled during the test, may produce a refer result for reasons other than hearing loss.
For babies in some circumstances (particularly neonatal intensive care graduates), an alternative test — automated auditory brainstem response (AABR) — may be used. This test measures electrical activity in the auditory nerve in response to sound, using small sensors placed on the head. It provides a more comprehensive assessment of the hearing pathway.
What a Refer Result Means
A refer result means the test could not confirm clear responses in one or both ears. It does not mean the baby definitely has hearing loss — around five percent of babies receive a refer result on initial testing, and the majority of these are confirmed as having normal hearing on repeat testing. Common reasons for a refer result include residual fluid in the ear canal, movement during the test, or background noise.
A refer result is followed up with a repeat test, typically offered within a few weeks. If the repeat test also refers, the baby is referred to an audiologist for comprehensive diagnostic assessment.
If Hearing Loss Is Confirmed
If permanent hearing loss is confirmed, early intervention begins promptly. Hearing aids can be fitted from around four weeks of age if needed, and cochlear implants are considered for babies with severe or profound sensorineural hearing loss. Specialist support — including speech and language therapy, specialist teacher of the deaf support, and connecting with the family to support communication and language development — begins immediately.
The evidence for the benefit of early identification is clear: babies whose hearing loss is identified by three months and who receive intervention by six months develop language and communication skills significantly better than those whose hearing loss is identified later. The UK newborn hearing screening programme was specifically designed to achieve this early identification.
Key Takeaways
The Newborn and Infant Physical Examination (NIPE) includes a hearing screening test for all babies in the UK, usually offered within the first few weeks of life. The most common test — automated otoacoustic emissions (AOAE) — uses a small probe in the ear to measure the cochlea's response to sound. A 'refer' result means the test needs to be repeated, not that the baby definitely has hearing loss. Around one to two in every thousand babies will be confirmed to have permanent hearing loss; early identification and intervention (hearing aids or cochlear implants) significantly improves speech and language outcomes.
