Hearing Impairment
When to worry about hearing in a 6-to-9-month-old
By 6–9 months most babies turn to sounds, babble and react to familiar voices. A consistent pattern of missing these is worth a prompt hearing check — not panic. Worry is a reason to assess; only a clinician can confirm hearing impairment.
When your baby doesn't turn to your voice the way you hoped, the worry is real — and there is a clear, hopeful path forward.
In short
With hearing impairment, early signs at 6–9 months are worth checking — not panicking over. By this age, most babies turn towards sounds, babble with strings like ba-ba or da-da, quieten or react to a familiar voice, and startle to a loud noise. Worry is reasonable if you see a pattern of these missing. Worry is a reason to check — it is not, by itself, a diagnosis.What to watch (6–9 months)
- Does not turn eyes or head towards a new sound or your voice
- Babbling has not started, or has gone quiet after starting
- No startle or settling to loud or soothing sounds
- Doesn't seem to enjoy or respond to music, rattles or your singing
- Doesn't recognise your voice or calm when you speak from out of sight
A single quiet day proves nothing — babies have off moments. A consistent lack of response across days is the real flag, and the kind thing is to have it checked promptly.
The science, briefly
Hearing is the foundation for speech and language — the brain's language pathways are most receptive in the first years of life. This is why newborn hearing screening matters, and why any concern after it deserves a prompt formal hearing check rather than waiting. Identified early, children with hearing impairment can thrive with the right support; delay is the real risk, not the hearing difference itself.The Pinnacle way
Only a qualified clinician can tell whether this is a hearing difference or a passing phase — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care, never from an online form. Where hearing is confirmed, our speech therapy team builds early listening and language together with your audiologist. Backed by 25 million+ therapy sessions and 4.95 lakh+ families across 70+ centres, our aim is your child listening, communicating and thriving.Trusted sources

What to watch
Seek a prompt hearing check if your baby consistently doesn't turn to sounds or your voice, babbling hasn't started or has gone quiet, or there's no startle to loud noise across several days.
Try this at home
Play simple sound games: call your baby's name softly from one side, pause, then watch for a turn. Sing and rattle from out of sight. Daily back-and-forth listening play is gentle, powerful practice.

Frequently asked
My baby passed the newborn hearing screen — can hearing problems still appear later?
Yes. Some hearing differences develop or become apparent after birth, so a passed newborn screen doesn't rule out later concern. If your 6-to-9-month-old isn't responding to sounds or voices, a fresh hearing check is worthwhile.
Is it normal for a 6-month-old not to babble much?
Babbling usually emerges around 6 months, but babies vary. A single quiet phase is common. Persistent absence of babble, or babble that started then stopped, is worth checking with your paediatrician.
Can hearing impairment be helped if found early?
Absolutely. The first years are when the brain's language pathways are most receptive, so early support — hearing aids, listening therapy and speech-language work — can help children thrive. Early action is the hopeful path.
