Children's Hearing Test

Why Children's Hearing Matters

Hearing is fundamental to every aspect of a child's development — from their first words and the ability to follow a bedtime story, to forming friendships and thriving in the classroom. Unlike adults, who can often compensate for gradual hearing changes, children depend on clear, consistent auditory input to acquire speech and language during a critical developmental window. When hearing loss goes undetected, even a mild loss can cascade into delayed speech, reduced vocabulary, difficulty with reading and literacy, behavioural challenges, and social isolation.

The scale of childhood hearing loss in the UK is significant. According to the National Deaf Children's Society (NDCS), approximately 50,000 children in the UK are deaf or have permanent hearing loss. The RNID (Royal National Institute for Deaf People) estimates that around 1 to 2 babies in every 1,000 are born with permanent hearing loss in one or both ears. Temporary hearing loss is even more common — glue ear (otitis media with effusion) alone affects an estimated 8 out of 10 children by the age of ten, according to the NDCS. These figures underline why the UK has invested in one of the most comprehensive childhood hearing screening programmes in the world, with checks from the very first days of life through to school entry and beyond.

The NHS Newborn Hearing Screening Programme (NHSP)

The NHS Newborn Hearing Screening Programme (NHSP) is one of the UK's most successful public health initiatives. Rolled out nationally in England in 2006, with equivalent programmes operating in Scotland, Wales, and Northern Ireland, it offers a free hearing screen to every baby born in the UK — typically within the first few weeks of life, before the family leaves hospital or during an early home visit by a health visitor.

The first-line screening test is the Automated Otoacoustic Emissions (AOAE) test. A small, soft-tipped earpiece is placed gently in the baby's ear, and the device plays quiet clicking sounds. A healthy cochlea (inner ear) produces faint echo-like sounds in response — otoacoustic emissions — which the device detects. The test takes just a few minutes per ear, is completely painless, and most babies sleep through it.

If a clear response is not obtained on the first attempt (which can happen for many reasons including fluid in the ear canal, background noise, or a restless baby), the screen is repeated. If the second attempt also gives an unclear result, the baby is referred for a second-tier test — the Automated Auditory Brainstem Response (AABR) — which measures the auditory nerve's response to sound using small sensor electrodes placed on the baby's head. This, too, is painless and usually performed while the baby sleeps.

Parents should be reassured that a referral for further testing does not necessarily mean their baby has permanent hearing loss. Many babies referred after the initial screen are subsequently found to have normal hearing. However, the programme is designed to catch the small number who do have a loss, because the evidence is overwhelming: children whose hearing loss is identified and supported before the age of six months achieve significantly better speech, language, and educational outcomes than those identified later. The NHSP screens over 98% of eligible babies each year and has transformed early identification in the UK.

Hearing Checks in Infancy and Early Childhood

Beyond the newborn screen, the UK's child health surveillance programme includes further hearing milestones at key developmental stages:

• Health visitor distraction test (8–9 months): During the standard health visitor developmental review, a baby's response to sounds is observed. The health visitor or an assistant produces sounds at controlled levels from behind the baby while another person engages the child from the front. A normally hearing baby will turn towards the sound. Although this test has been phased out in some areas in favour of targeted surveillance, it remains in use in parts of the UK and serves as an important informal check on auditory development.
• Developmental reviews (12–24 months): Health visitors and GPs monitor speech and language milestones. Delayed babbling, failure to respond to their name, or absence of single words by 18 months can all indicate hearing difficulty and should prompt a referral to paediatric audiology.
• School-entry hearing screening (age 4–5): In Reception year, a sweep hearing test is offered, usually conducted by the school nursing team. Children wear headphones and listen for quiet tones at set frequencies (typically 1, 2, and 4 kHz at 20 dB HL), raising their hand or pressing a button when they hear a sound. This simplified version of pure tone audiometry is designed to identify children with previously undetected hearing loss — including those who have developed glue ear since infancy. Children who do not pass are referred to audiology for a full diagnostic assessment.

At any point, if a parent, health visitor, teacher, or GP has concerns about a child's hearing, a direct referral to paediatric audiology can be made. You do not need to wait for a routine screen — early action is always the right approach.

Signs of Hearing Loss in Babies, Toddlers, and Children

Hearing loss in children can be present from birth (congenital) or develop later (acquired). Because children cannot always articulate that they are struggling to hear, parents and carers play a critical role in spotting the signs. The NDCS and RNID highlight the following indicators at different ages:

Babies (0–12 months)

• Not startling or waking to sudden loud sounds
• Not turning towards familiar voices or sounds by 4–6 months
• Not babbling or making vocal sounds by 7–9 months
• Not responding to their own name by 9–12 months

Toddlers (1–3 years)

• Delayed speech or limited vocabulary compared to peers
• Difficulty following simple instructions unless face-to-face
• Wanting the television volume turned up higher than others need
• Frequent ear infections or periods of inattentiveness

School-age children (4+ years)

• Difficulty following conversations, especially in noisy classrooms
• Frequently asking "what?" or "pardon?" or asking for repetition
• Falling behind academically, particularly in reading and phonics
• Behavioural changes such as withdrawal, frustration, or tiredness at the end of the school day
• Speaking more loudly than necessary

If you recognise any of these signs, speak to your GP, health visitor, or school nurse promptly. A referral to paediatric audiology can be arranged at any age, and all assessments and follow-up services are completely free on the NHS.

Glue Ear — The Most Common Cause of Childhood Hearing Loss

Glue ear (otitis media with effusion) is by far the most frequent cause of temporary hearing loss in children. It occurs when thick, sticky fluid accumulates in the middle ear space behind the eardrum, dampening the transmission of sound and causing a mild to moderate conductive hearing loss. The condition is most common between the ages of 2 and 5, peaking during the winter months, and is often associated with colds, ear infections, and enlarged adenoids.

Most cases of glue ear resolve on their own within three months — the NICE guideline (NG233) recommends a period of active monitoring (watchful waiting) before considering intervention. However, persistent glue ear lasting more than three months, particularly when accompanied by significant hearing loss, can have a measurable impact on a child's speech, language, and learning. In these cases, treatment options include:

• Autoinflation: A simple technique using a special balloon (Otovent) that the child blows up using their nose, helping to open the Eustachian tube and drain fluid.
• Grommets (ventilation tubes): Small tubes inserted into the eardrum under general anaesthetic, allowing air into the middle ear and fluid to drain. Grommets are one of the most commonly performed childhood surgical procedures in the UK. They typically fall out naturally after 6 to 12 months as the eardrum heals.
• Hearing aids: In some cases, particularly where surgery is not appropriate, temporary hearing aids may be offered to ensure the child can hear clearly while the glue ear is present.
• Adenoidectomy: Removal of the adenoids may be recommended alongside grommets if the adenoids are contributing to Eustachian tube dysfunction.

Tympanometry is a key diagnostic tool for glue ear — it measures the movement of the eardrum and can quickly confirm the presence of fluid in the middle ear. If your child has recurrent ear infections or persistent hearing difficulty, ask your GP about a tympanometry assessment.

Paediatric Audiometry Techniques — How Children's Hearing Is Tested

Testing a child's hearing requires age-appropriate techniques that account for their developmental stage and ability to cooperate. Paediatric audiologists are specially trained to assess hearing accurately in children from birth through to adolescence, using the following methods:

Visual Reinforcement Audiometry (VRA) — 6 months to 2.5 years

VRA is used for infants and young toddlers who can sit supported but are too young for play audiometry. The child sits on a parent's lap in a soundproofed room. Sounds are played through speakers or insert earphones, and when the child turns towards the sound, they are rewarded with an animated visual display — a lit-up puppet, moving toy, or cartoon on a screen. By conditioning the child to associate sound with the visual reward, the audiologist can determine hearing thresholds across different frequencies.

Play Audiometry — 2.5 to 5 years

Play audiometry turns the hearing test into a game. The child wears headphones (or insert earphones) and is taught to perform a task each time they hear a sound — for example, putting a peg in a board, dropping a ball into a bucket, or placing a piece in a puzzle. This conditioned play response allows the audiologist to measure hearing thresholds at specific frequencies in each ear, producing a reliable audiogram.

Pure Tone Audiometry — 5 years and older

From around age five, most children can participate in a standard pure tone audiometry test, pressing a button or raising their hand when they hear a tone — the same procedure used for adults. The audiologist may use child-friendly instructions and encourage the child throughout to maintain attention.

Objective Tests

For newborns, very young infants, or children who cannot cooperate with behavioural testing, objective tests that require no active response are used:

• Otoacoustic emissions (OAE): Measures sounds produced by the cochlea — used in newborn screening and as a diagnostic tool at any age.
• Auditory brainstem response (ABR): Measures electrical activity in the auditory nerve and brainstem — the gold standard for estimating hearing thresholds in babies too young for behavioural tests.
• Tympanometry: Assesses middle ear function — invaluable for diagnosing glue ear and eardrum problems.

Treatment and Support for Children with Hearing Loss

When hearing loss is confirmed, the treatment pathway depends on the type, degree, and cause of the loss. The UK offers a comprehensive range of interventions, all available free through the NHS:

• Hearing aids: NHS hearing aids for children are provided completely free, including fitting, programming, batteries, repairs, earmoulds, and lifelong aftercare. Modern paediatric hearing aids are small, robust, and available in a range of colours that children can choose. They are fitted and verified using real-ear measurement and regularly updated as the child grows and their hearing changes.
• Cochlear implants: For children with severe to profound sensorineural hearing loss who do not benefit sufficiently from hearing aids, cochlear implantation may be considered. The UK has several specialist paediatric cochlear implant centres, and the procedure is funded by the NHS. Research published in the British Medical Journal and supported by NICE (Technology Appraisal TA566) confirms that early cochlear implantation — ideally before the age of 2 — leads to significantly better speech and language outcomes.
• Bone-anchored hearing devices: For children with persistent conductive hearing loss or single-sided deafness, bone-anchored hearing devices may be an option. These bypass the outer and middle ear, sending sound directly to the cochlea through bone vibration.
• Grommets: As described above, grommets are the standard surgical treatment for persistent glue ear with hearing loss.
• Speech and language therapy: Children with hearing loss — whether permanent or temporary — may be referred to a speech and language therapist (SLT) to support their communication development. SLT is available free on the NHS and can be provided in clinics, schools, or at home.
• Educational support: Children with hearing loss are entitled to support in school under the Equality Act 2010 and the Children and Families Act 2014. This may include a Teacher of the Deaf (a qualified teacher with specialist training), radio aid systems (which stream the teacher's voice directly to the child's hearing aids), preferential seating, acoustic treatment of classrooms, and an Education, Health and Care Plan (EHCP) for children with more complex needs.

The NDCS offers a wealth of free resources for families, including a helpline, family support workers, and technology grants. Early identification and a joined-up approach between audiology, speech therapy, education, and family support can make a profound difference to a child's life chances.

Causes of Hearing Loss in Children

Childhood hearing loss has many possible causes, broadly divided into congenital (present at birth) and acquired (developing after birth):

Congenital causes

• Genetic factors: Approximately 50% of congenital hearing loss is genetic, according to the NHS. Some genetic hearing losses are syndromic (associated with other conditions), while others are non-syndromic.
• Infections during pregnancy: Maternal infections including cytomegalovirus (CMV), rubella, and toxoplasmosis can cause hearing loss in the developing baby. CMV is the most common non-genetic cause of congenital hearing loss in the UK.
• Prematurity and low birth weight: Babies born prematurely, particularly those requiring neonatal intensive care, are at higher risk of hearing loss.
• Birth complications: Severe jaundice, lack of oxygen during birth, or the need for certain medications in the neonatal period can increase risk.

Acquired causes

• Glue ear: The most common cause of temporary hearing loss in children, as discussed above.
• Ear infections (otitis media): Recurrent middle ear infections can cause temporary or, in severe cases, permanent hearing loss.
• Meningitis: Bacterial meningitis is a significant cause of acquired sensorineural hearing loss in children. Children who have had meningitis should have their hearing tested urgently.
• Noise exposure: Increasingly, children and teenagers are at risk from prolonged use of headphones at high volume and attendance at loud events.
• Measles, mumps, and other infections: These can occasionally damage hearing, underscoring the importance of vaccination.
• Head injury: Trauma to the head can damage the inner ear or auditory nerve.

How to Get Your Child's Hearing Tested

Getting your child's hearing checked is straightforward, and all NHS children's hearing services are completely free. Here are the pathways available:

• Newborn screening: This is offered automatically to all babies in the UK. If your baby was not screened before leaving hospital, your health visitor will arrange it.
• GP referral: At any age, your GP can refer your child directly to the local paediatric audiology service. Describe your concerns in detail — what situations are difficult, what your child does or does not respond to, and whether speech and language seem age-appropriate.
• Health visitor or school nurse referral: Health visitors (for under-5s) and school nurses can also arrange a referral to paediatric audiology. Many parents find it helpful to speak to the school nurse if their child is struggling to hear in the classroom.
• School-entry screening: If your child is in Reception and is offered a sweep hearing test at school, ensure you return the consent form so they are included.
• Self-referral: In some areas, parents can refer directly to paediatric audiology without going through the GP. Check with your local NHS trust.

If you suspect your child has hearing difficulty, do not wait. The earlier hearing loss is identified and managed, the better the outcome for speech, language, learning, and social development. The UK's paediatric audiology services are world-class — and they are free to every child.
