Hearing Concerns in a Child: Signs and Next Steps

Hearing loss in children can range from mild temporary fluid-related muffling to permanent loss present from birth. Early identification matters most because hearing drives early language development.

Why hearing matters so much in the early years

The brain builds language pathways during a critical window in early childhood. Hearing is the input that drives this process. Even moderate hearing loss during this window can slow or alter speech and language development in ways that show up later in school 1.

All newborns in most U.S. states receive a hearing screen before leaving the hospital as part of the 1-3-6 benchmark: screened by 1 month, evaluated by 3 months if concerns arise, and in early intervention by 6 months if hearing loss is confirmed 3. But hearing can also change after birth — from fluid in the middle ear, infections, genetic conditions that emerge gradually, or noise exposure. The newborn screen cannot detect what develops later, which is why ongoing surveillance through well-child visits and parental observation matters.

Signs by developmental stage

In infants: not startling to sudden loud sounds, not turning toward a parent's voice by 4 months, not babbling by 6 months, not responding to their name by 9–12 months 1.

In toddlers: not using single words by 12–15 months, not using two-word phrases by 24 months, often not responding when called from another room, seeming to hear inconsistently.

In preschool children: speech significantly harder to understand than peers, frequently asking for repetition, watching faces very closely when spoken to, turning up the volume on screens.

In school-age children: difficulty following multi-step directions, struggles in noisy classrooms, mishearing words in ways that suggest a high-frequency pattern, falling behind academically in ways not explained by other factors.

The most common cause of temporary hearing loss in children

Otitis media with effusion — fluid behind the eardrum without signs of acute infection — is among the most common causes of hearing loss in young children. By age 3, approximately five out of six children will have had at least one ear infection 2. The fluid acts like a plug, muffling sounds. It can persist for weeks or months after an ear infection, or develop silently without any preceding infection.

This type of hearing loss is typically temporary; once the fluid clears, hearing returns to normal. But if it lasts long enough during critical developmental windows, a hearing test and a conversation about management — including ear tubes if the fluid is persistent — may be appropriate.

Permanent hearing loss: causes and what to know

Permanent hearing loss in children can be congenital (present at birth) or acquired. Genetic factors account for a large share of congenital hearing loss, most of it non-syndromic — hearing loss without other major associated conditions. Other causes include certain infections during pregnancy, premature birth, jaundice requiring treatment, or rare complications 1.

Acquired permanent hearing loss after birth can result from certain infections (meningitis, measles), prolonged exposure to loud noise, head trauma, or certain medications. Unilateral hearing loss — affecting only one ear — is sometimes missed in everyday life and may not be detected until the child starts school; it still warrants evaluation and management.

What a hearing evaluation involves

A pediatric audiologist can test hearing reliably from infancy onward using age-appropriate methods. For infants, testing uses physiological measures like otoacoustic emissions (OAE) or auditory brainstem response (ABR) testing, which require no cooperation from the child 1.

Older children can participate in a standard pure-tone audiogram in a soundproof booth, which maps which frequencies and volumes the child can and cannot hear. Results guide decisions about management — monitoring, ear tubes for fluid-related loss, hearing aids, or cochlear implant evaluation for significant permanent loss. A referral to audiology from a pediatrician is straightforward and appropriate whenever a parent has concerns.

Common questions

My toddler's newborn hearing screen was normal. Could she still develop hearing loss?

Yes. The newborn screen only checks hearing at birth. Some forms of hearing loss are progressive — they worsen gradually over months or years. Others are acquired after birth. Ongoing monitoring at well-child visits and attention to developmental milestones are part of how later-onset hearing loss gets identified.

My child hears some things fine but misses others — is that possible with hearing loss?

Yes. Hearing loss is often frequency-specific. High-frequency hearing loss, for example, means a child may hear low-pitched sounds like a drum just fine but miss consonants like 's', 'f', and 'th' that carry high-frequency information. This can look like mishearing, inattention, or unclear speech rather than obvious deafness.

How do I ask for a hearing test at a well-child visit?

It is entirely appropriate to say to the pediatrician: 'I have concerns about my child's hearing — can we do a hearing test or refer to audiology?' Parents know their children well, and a concern raised at a visit should always be taken seriously. Routine hearing screening is part of well-child care at certain ages, and a referral to audiology is straightforward.

When to get care right away

  • —Sudden hearing loss in one or both ears — especially in an older child
  • —Hearing loss after a head injury
  • —Significant ear pain, dizziness, or ringing in the ears alongside hearing change
  • —A newborn who did not pass the hospital hearing screen and has not yet had follow-up

Sudden hearing loss is treated as an urgent situation in children — same-day or next-day evaluation is appropriate. If the child also has signs of meningitis (stiff neck, light sensitivity, high fever, and severe headache), call 911 or go to the emergency department immediately.
