Hearing Impairment
Worried about hearing loss in your 3-to-6-month-old?
At 3–6 months, hearing is watched gently, not feared. Expect startle to loud sounds, calming to your voice, turning towards sound, and early cooing. A consistent absence — or NICU, prematurity, jaundice or family history — warrants a hearing check. Only a clinician can confirm.
When your baby doesn't startle at a loud sound or turn towards your voice, the worry is real — and checking is the kind, clear thing to do.
In short
At 3 to 6 months, hearing is something you watch gently, not something you panic over. Your baby should startle to sudden loud sounds, settle or calm to a familiar voice, and begin turning their eyes or head towards where a sound comes from. By around 6 months, most babies begin cooing and making vowel-like sounds back at you. If these are consistently absent, it is worth a hearing check — sooner if your baby was born early, spent time in NICU, had jaundice needing treatment, or there is hearing loss in the family.What to watch by this age
- Sound response — no startle to loud, sudden noises
- Voice — does not quieten, smile or turn towards your voice
- Locating — by 5–6 months, no attempt to turn towards a sound
- Voice play — little or no cooing, gurgling or babble back at you
One quiet day is normal. A steady pattern of no response is the real flag.
The science, briefly
Hearing is the foundation of spoken language — a baby learns to talk by first listening. This is why India's newborn screening programmes aim to identify hearing impairment (WHO ICD-11) early, and why the CDC and AAP list these listening milestones. Importantly, a baby who passed a newborn hearing screen can still develop hearing loss later, so ongoing watching matters. Identified early, support begins early — and language outcomes improve markedly.The Pinnacle way
A passing observation at home is reassuring, but only a qualified clinician can confirm hearing — usually through an audiology test, never an online form. At Pinnacle, any clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care. We look at hearing alongside early communication, and where helpful guide you towards speech therapy support. The aim is simple: your baby listening, babbling and thriving.Trusted sources

What to watch
Seek a hearing check sooner if your baby was premature, spent time in NICU, had jaundice needing treatment, has a family history of hearing loss, or shows a steady pattern of no startle and no turning towards your voice.
Try this at home
Play gentle sound games: call your baby's name softly from one side, then the other, and watch for a turn of the eyes or head. Sing and chat face-to-face daily — it builds listening and invites those first coos back to you.

Frequently asked
My baby passed the newborn hearing screen — can they still have hearing loss?
Yes. A passing newborn screen is reassuring, but some hearing loss develops later in infancy. That is why continuing to watch listening milestones — startling to loud sounds, calming to your voice, turning towards sound, and beginning to coo — matters through these months.
Is it normal for my 4-month-old to not always respond to sounds?
Occasional non-response is completely normal — babies sleep deeply, get absorbed, or simply ignore familiar noise. The flag is a consistent pattern of no startle to sudden loud sounds and no turning towards your voice. A pattern, not a single quiet day, is the reason to check.
Which babies should have a hearing check sooner?
Babies who were born premature, spent time in NICU, had jaundice needing treatment, had certain infections, or have a family history of childhood hearing loss carry higher risk. For these babies, an earlier and ongoing audiology check is wise even if home responses seem fine.
