Early Signs of Hearing Impairment at 6-to-9 Months
Between 6 and 9 months, signs a baby may not be hearing well include not turning towards sounds or voices, little or fading babble, not responding to their name, and not startling at loud noises. These don't confirm hearing loss but are a clear signal to arrange a prompt hearing check — early support protects speech and language.
In this answer 5 sections
By six months, most babies are turning towards the voices and sounds they love — so when a little one seems not to notice, it's worth a gentle, timely check.
In short
Between 6 and 9 months, signs that a baby may not be hearing well include not turning towards sounds or voices, little or no babbling, not responding to their name, and not being soothed or startled by everyday sounds. None of these confirm hearing loss on their own — but they are a clear signal to arrange a hearing check soon, because early support makes a real difference to speech and language.
What to watch between 6 and 9 months
- Doesn't turn towards your voice, a rattle, or sounds coming from the side or behind
- Little or no babbling — by this age many babies repeat sounds like "ba-ba" or "da-da"; babbling may begin and then fade if hearing is reduced
- No reaction to loud sounds — not startling, blinking, or stilling when a door bangs or a toy makes noise
- Doesn't respond to their name or to familiar voices nearby
- Not calmed by your voice alone, or seems unusually quiet and unresponsive to sound
- Watches your face intently but misses sounds when they can't see you
A baby who hears in one ear may still turn and babble, so subtle or one-sided hearing loss can be easy to miss — which is why a formal check matters even with mild concerns.
The science, simply
Hearing is the gateway to spoken language. The first months of life are a sensitive window when the brain learns to map sounds to meaning. When sound doesn't reach the brain clearly, babbling and early words can be delayed. Many babies in India have newborn hearing screening — but hearing can change after birth, so ongoing watching at 6–9 months remains important. Identifying reduced hearing early, and supporting it, helps language develop on track.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Arrange a same-week hearing check if babbling begins and then fades, if your baby doesn't startle to loud sounds, or doesn't turn to your voice — especially if newborn screening was missed or there's a family history of hearing loss.
In everyday life
Play a simple sound game: out of your baby's sight, call their name or shake a soft rattle to one side, then the other. A baby who hears well will usually turn or still to listen.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
My baby passed the newborn hearing test — can hearing still be a problem at 6 months?
Yes. Newborn screening is valuable, but hearing can change after birth due to infections, fluid in the ears, or other causes. If you notice your baby no longer turns to sounds or babbles less, arrange a fresh hearing check even if the newborn test was normal.
My 8-month-old babbles but doesn't always respond to their name — should I worry?
Not responding to their name every time can be normal at this age, especially when a baby is absorbed in play. But if it happens consistently, alongside not turning to sounds or reduced babbling, it's worth a hearing check to be sure.
Is reduced babbling always a sign of hearing loss?
No. Babbling that starts and then fades can be a sign worth checking, but it can have other causes too. Only a clinician and an audiologist can confirm whether hearing is the reason — so a check is the right next step rather than waiting.
