My baby passed the newborn hearing screen. Does that mean their hearing is fine?

A typical newborn screen result is genuinely reassuring — it means no significant hearing difference was present at that moment. But hearing loss can develop or progress after birth, so ongoing checks remain worthwhile. The AAP recommends periodic hearing screening at well-child visits throughout childhood and adolescence, not just at birth.

My child's newborn screen came back 'unclear'. Should I be concerned?

An unclear result at the newborn stage most often reflects practical factors — fluid temporarily in the ear canal, a slightly unsettled baby, or background noise during the test — rather than confirming hearing loss. The important step is attending the follow-up audiology appointment, which uses a more detailed assessment. Many babies referred at this stage are found to have typical hearing when tested again.

My toddler has had several ear infections. Could these be affecting their hearing?

Repeated ear infections can lead to fluid building up in the middle ear, which temporarily reduces how well sound travels through. This is called otitis media with effusion (glue ear). For most children it resolves naturally within a few months, but if your child has had recurrent infections or you notice them seeming less attentive to sound, turning up the TV, or lagging slightly in speech, it is a good time to mention it at their next doctor's visit.

At what age should my child have a formal hearing test?

In addition to the newborn screen, current AAP guidance recommends objective hearing screening at ages 4, 5, 6, 8, and 10, and at least three more checks between ages 11 and 21. Children with risk factors — such as a family history of early hearing loss, prematurity, or a history of bacterial meningitis — may need earlier or more frequent assessment. Your child's doctor can advise based on their individual history.

How loud is too loud for my child's headphones?

The WHO recommends keeping children's personal listening devices below 75 dB, and a practical guide is to keep volume at or below 60% of maximum. At louder levels — say, 90 dB — safe weekly listening time drops to around four hours. Noise-cancelling headphones are helpful because they reduce background noise, so children naturally listen at a lower volume to hear clearly.

Hearing Matters: Why Early Hearing Checks Shape Speech and Learning

From newborn screening onward, hearing is the foundation of language.

6 min read · Reviewed against official sources

Most parents watch closely for a baby's first smile, first steps, first words. But the sense that quietly enables all of those milestones — hearing — often goes unchecked beyond the newborn period. Globally, around 95 million children aged 5 to 19 live with some degree of hearing difficulty, according to the WHO. The reassuring news: about 60% of childhood hearing loss is preventable, and the cases that cannot be prevented can almost always be identified early enough to protect language development.

How Hearing Shapes Speech and Learning

A child does not simply hear words and repeat them. Every sound a baby is exposed to in the first months of life is building the neural architecture of language. The brain is mapping phonemes, rhythms, and meanings in real time — a process that is especially intense across the birth-to-age-five window. When hearing is reduced during this period, the auditory pathways in the brain receive less input than they need, and language acquisition can slow.

The American Academy of Pediatrics (AAP) is clear on the stakes: unidentified congenital or acquired hearing loss is linked to delays in speech and language development, lower academic performance, and difficulties with personal and social adjustment. The same body of research holds a genuinely hopeful counterpoint — early identification and appropriate intervention within the first six months of life has been shown to significantly reduce those developmental effects and to support language acquisition.

Newborn Hearing Screening: What Happens and Why It Matters

Between one and two babies in every 1,000 are born deaf or hard of hearing, making it one of the more common conditions identified at birth. Newborn hearing screening has become standard practice in many countries precisely because hearing loss is not visible, and babies cannot tell you they are missing sounds.

Two painless, objective methods are used. Otoacoustic emissions (OAE) places a small soft-tipped earpiece in the ear to detect sound echoes produced by the inner ear in response to a tone — the whole screen takes only a few minutes and can be done while the baby sleeps. If results are unclear, automated auditory brainstem response (AABR) follows: three small sensors placed on the head and neck measure the brain's electrical response to sounds, taking 5 to 15 minutes. Neither method causes any discomfort.

A widely used framework, the EHDI '1-3-6' benchmarks set out by the CDC, gives three clear timelines: screening by 1 month of age, a full diagnostic evaluation completed by 3 months if the initial screen requires follow-up, and enrollment in early intervention services by 6 months if a hearing difference is confirmed. These are not arbitrary timelines — they map onto the brain's most sensitive window for language learning.

Age-by-Age Signs Worth Knowing

A passed newborn screen is a reassuring starting point, not a lifelong certificate. Hearing loss can be progressive or late-onset, appearing months or years after a typical newborn result. Knowing what to look for at each stage helps parents notice changes early.

In the first year

Does not startle at sudden loud sounds
Does not turn toward a sound source by around 6 months of age
Responds to faces and visual cues but not to voice alone
Has not said a first word such as 'mama' or 'dada' by 12 months

Ages 1 to 3

No clear words by 12 to 15 months
Fewer than three meaningful words (beyond common ones) by 18 months
Not combining two or three words by age 2
Speech that is still unclear to unfamiliar adults at age 2.5

Older children

Seems to hear some sounds but not others
Frequently asks for things to be repeated
Consistently turns the television or music up very high
Appears inattentive or easily distracted, especially in group settings
Has difficulty following spoken directions

One reason hearing differences are easy to miss at home: children are skilled at using visual cues, context, and lip-reading to fill in what they cannot hear. Difficulties often become most apparent in noisier environments like classrooms, where there is more competing sound and less opportunity to compensate. Children also cannot reliably report gradual hearing changes themselves — they may not realise what they are missing.

Ear Infections and Temporary Hearing Reduction

Otitis media with effusion (OME), commonly known as glue ear, is one of the most frequent conditions of early childhood. Fluid collects in the middle ear — often without any pain, fever, or obvious sign of illness — and can muffle sounds enough to affect what a child hears day to day.

For most children, glue ear resolves on its own within weeks to a few months. In roughly one in ten children, fluid lingers or comes and goes repeatedly, and the NICE guidelines note a particular concern: OME peaks in the same early childhood years when the brain's auditory pathways are developing most rapidly. Persistent mild hearing reduction during this period can affect listening skills, language development, and behaviour — and may be interpreted as attention difficulties rather than a hearing issue.

Signs that glue ear may be affecting a child include: needing the TV louder than usual, not responding when called from another room, or seeming less engaged in conversation. These are worth mentioning at the next well-child visit rather than waiting to see if they pass.

How and When Hearing Is Formally Tested

For infants under six months, ABR and OAE testing can be done during natural sleep and are painless, typically taking between five minutes and an hour. From around age three to five, children can participate in behavioural audiometry — responding to tones by raising a hand or placing a block in a bucket.

The AAP's updated 2023 clinical report recommends a systematic schedule of objective hearing screening beyond the newborn period: at ages 4, 5, 6, 8, and 10, followed by at least three screenings between ages 11 and 21. This schedule reflects the reality that hearing loss can appear or progress at any point during childhood and adolescence, not only at birth.

Children with one or more hearing risk factors — including a family history of early hearing loss, prematurity, congenital infections such as cytomegalovirus (CMV), or a history of bacterial meningitis — should have at least one diagnostic audiology assessment by 24 to 30 months, even if the newborn screen returned a typical result. CMV alone accounts for approximately 25% of hearing loss identified by age four.

Protecting Hearing from Loud Sound

Noise-induced hearing loss is painless while it is happening, accumulates over time, and once it occurs, cannot be reversed — it cannot be medically or surgically corrected. In the United States alone, roughly 12.5% of children and adolescents aged 6 to 19 have already experienced some permanent hearing reduction from excessive noise, according to CDC data. Over one billion adolescents and young adults globally are at risk from unsafe listening through personal devices, according to WHO's 2021 World Report on Hearing.

Sounds at or below 70 dB are generally considered safe for extended exposure. WHO recommends keeping children's personal devices below 75 dB, and a practical rule of thumb is to keep volume at or below 60% of a device's maximum setting. At 90 dB (comparable to a shouted conversation), safe weekly listening time drops to around four hours. At 100 dB, around 20 minutes. Noise-cancelling headphones are a genuinely useful tool here: when children can hear clearly without competing with background noise, they naturally turn the volume down.

A Note on Prevention

Around 60% of childhood hearing loss is preventable. The WHO identifies several protective measures: immunisation against rubella and meningitis, good maternal and neonatal care, and early screening and management of ear infections. In Nepal and the broader South and Southeast Asia region — where more than 400 million people live with hearing loss, accounting for over a quarter of the global burden — chronic middle ear disease remains a meaningful contributor to childhood hearing difficulties. Studies of Nepali school children have found chronic suppurative otitis media (CSOM) in between 5% and 7.6% of children screened. Early identification through school hearing programs and prompt treatment of ear infections are among the most practical steps available.

Prevention, screening, and early support are not separate actions — they work as a sequence. A newborn screen identifies those who need early audiology assessment. Periodic screening through childhood catches late-onset or acquired changes. Safe listening habits protect the hearing children have. And a parent who knows what to watch for is often the first to notice when something is worth checking.

Key takeaways

Hearing is the foundation of language: the birth-to-age-five window is an especially sensitive period for building speech and communication, and even mild, temporary hearing reduction during this time can affect development.
The EHDI '1-3-6' benchmarks guide timing: screening by 1 month, diagnosis by 3 months, and early intervention enrolled by 6 months of age if a hearing difference is identified.
A passed newborn screen is not a permanent result — hearing loss can be progressive or late-onset. Periodic screening is recommended at ages 4, 5, 6, 8, 10, and into adolescence.
Glue ear (otitis media with effusion) is common and often painless; it can cause a temporary reduction in hearing that may look like inattention rather than a hearing issue.
Noise-induced hearing loss is irreversible and preventable: keeping children's device volume at or below 60% of maximum (under 75 dB) helps protect against cumulative damage.
Around 60% of childhood hearing loss is preventable through immunisation, good antenatal and neonatal care, and early treatment of ear infections.
