YOUR QUESTION. A CLEARER NEXT STEP.
Early indicators of hearing impairment a paediatrician should watch for
Refer for diagnostic audiology on any failed newborn hearing screen, absent startle or localisation to sound, no babble by 9–12 months, no single words by 15–18 months, stalled or regressing speech, or persistent parental concern. A normal newborn screen never excludes later or progressive loss; high-risk infants need surveillance regardless.

Hearing is the gateway to spoken language — and the quietest delays are the easiest to miss. The paediatrician who notices the pattern early changes a child's entire language trajectory.
In short
Watch for failed or absent newborn hearing screening, and for any infant who does not startle to loud sound, does not turn to voice by 6 months, has no babble by 9–12 months, or no single words by 15–18 months. Persistent parental concern, speech that plateaus or regresses, and recurrent otitis media all warrant prompt audiological referral — and a normal newborn screen never excludes later-acquired or progressive loss.
Early indicators by age
Neonate / early infancy
- No referral or a fail on OAE/AABR newborn hearing screening — or screening not completed
- Absent startle (Moro) or eye-blink to sudden loud sound
- Risk factors: NICU admission, hyperbilirubinaemia requiring exchange, congenital CMV, family history of childhood deafness, craniofacial anomalies
3–9 months
- Does not quieten or turn towards a familiar voice
- No localising to sound by 6 months
- Reduced vocal play; babble that is monotonous, late or fading
9–18 months
- No canonical babble by 9–12 months
- Does not respond to name or simple words ("no", "bye") in a quiet room
- No single words by 15–18 months; reliance on visual cues and gesture
Toddler and beyond
- Stalled or regressing speech; unclear articulation; frequent "what?"
- Inattentive only when not facing the speaker; turns TV volume up
- Recurrent or persistent otitis media with effusion (conductive contribution)
When to refer
"Wait and see" is never appropriate for suspected hearing loss — auditory deprivation in the first years has lasting language consequences. Refer for diagnostic audiology (not a repeat screen) on any failed newborn screen, any high-risk infant regardless of screen result, and whenever a parent reports concern about hearing or speech. Aligns with WHO ICD-11 category hearing impairment (AB52). Arrange ENT review for recurrent effusion, and begin parallel speech therapy input once loss is confirmed — amplification or implantation plus language intervention is most effective when early.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — the AbilityScore® is a clinician-administered structured assessment that profiles communication and developmental domains to complement audiology, not replace it. Once hearing is addressed, our speech therapy team supports the language catch-up that amplification alone cannot deliver.
Trusted sources
Consistent with WHO ICD-11 hearing impairment categories, CDC "Learn the Signs. Act Early." developmental milestones, the Indian Academy of Pediatrics, and American Academy of Pediatrics (HealthyChildren.org) guidance on early hearing detection and intervention.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Escalate to same-week diagnostic audiology on any failed newborn screen, any high-risk infant (NICU, congenital CMV, family history), or any reported speech regression — these warrant action, not monitoring. A passed newborn screen does not rule out progressive or late-onset loss.
In everyday life
High-yield consult check: confirm newborn screen result, test localisation to a soft voice out of sight, and ask the parent directly 'do you ever feel they don't hear you?' — parental concern is a sensitive early indicator.

Bring your questions to a first visitQuestions families ask
Does a passed newborn hearing screen rule out hearing impairment?
No. Newborn screening (OAE/AABR) detects congenital loss but cannot exclude progressive, late-onset or acquired hearing loss. High-risk infants — NICU graduates, congenital CMV, family history — need ongoing audiological surveillance regardless of screen result, and any later parental or clinical concern warrants fresh diagnostic audiology.
What is the single most important early red flag?
Absent canonical babble by 9–12 months, or no consistent response to a familiar voice or name in a quiet room. Combined with any failed screen or parental concern, this justifies prompt referral for diagnostic audiology rather than a repeat screen.
Should I refer for audiology or for speech therapy first?
Refer for diagnostic audiology first to characterise the loss; arrange speech and language intervention in parallel once loss is confirmed. Recurrent otitis media with effusion also warrants ENT review for a treatable conductive component.
