Why Isn’t My Baby Reacting to Sounds — Is It Normal?

Medically reviewed by pediatrician Alexandra Zglavosiy
From the first weeks of life, babies respond to sounds, and by 2–3 months they show emotions when hearing a voice. If your baby doesn’t react to sounds or turn toward them, it’s best to talk to your pediatrician. The earlier hearing issues are detected, the better the chances of addressing them and avoiding speech delays. Even if the newborn hearing screening was normal, ongoing observation is important.

What’s Inside
Quick takeaways
- From the first weeks, babies react to loud and sudden sounds.
- By 2–3 months, they respond emotionally to voices — smiling or becoming more animated.
- If your baby doesn’t turn toward sounds or react to voices, speak with your pediatrician.
- The earlier hearing issues are identified, the better the chances of full compensation.
- A newborn hearing screening doesn’t rule out later problems — it’s important to observe your baby’s reactions.
How hearing develops during the first year
Hearing development follows a natural timeline:
| Age | What happens |
| 0–1 month | Startles at loud sounds, freezes briefly |
| 1–2 months | Calms to voices, reacts to noise |
| 2–3 months | Starts cooing, listens to voices |
| 4–6 months | Turns head toward sound, babbles |
| 6–9 months | Recognizes familiar voices, "talks" with parents |
| 9–12 months | Understands familiar words, responds to name |
Keep in mind — these stages are individual. Small delays are possible, especially in preterm babies.
When to be concerned
Talk to your pediatrician if you notice one or more of the following:
- Baby doesn’t startle at loud sounds from birth
- Doesn’t turn head toward sounds by 4–6 months
- Doesn’t coo or “talk” by 5 months
- Doesn’t respond to their name by 9 months
- Shows no interest in voices or sounds
Even if hearing was screened at birth, issues may appear later due to infections, earwax buildup, or ear infections.
What parents can do
- Watch reactions to sounds — clap your hands, play soft music, talk to your baby
- Play with your voice — sing, vary intonation, say the baby’s name
- Check for responses — stillness, alertness, searching for the sound
- If there’s no response, consult your pediatrician — they may refer for a hearing test
Why early action matters
The sooner a hearing problem is found, the more effective the correction — via hearing aids, cochlear implants, or speech therapy.
If addressed early, the brain has time to form the right connections, giving the baby every chance to develop age-appropriate speech.
Frequently Asked Questions About Babies Who Don't React to Sounds
When should babies start reacting to sounds?
Most babies react to loud sounds from the first weeks of life. By 2–3 months, they usually listen to voices, smile, or become more animated during interaction. By 4–6 months, many babies turn their head toward sounds and start babbling.
Is it normal if my baby doesn't turn toward sounds?
Small differences in development can happen, especially in premature babies. But if by 4–6 months your baby does not react to voices, turn toward sounds, or respond emotionally during interaction, it's worth discussing with your pediatrician.
Why might my baby not react to voices or noises?
Hearing difficulties can be linked to ear infections, earwax buildup, or other hearing problems. Some issues may appear later, even after a normal newborn hearing screening.
What should I do if my baby doesn't respond to sounds?
Try observing how your baby reacts to voices, music, and everyday sounds. If your baby does not startle, look for the source of sounds, or respond to their name, your pediatrician may recommend a hearing evaluation.
