Baby Room Noise Meter
Is the nursery quiet enough for sleep? Measure the noise in seconds.
What it does
- Instant decibel reading. Point your phone and see the room's noise level in dB — no setup, no calibration faff.
- Calm-enough-to-sleep zones. Color tells you at a glance: green is calm, amber is a bit loud, red means it may disturb a sleeping baby.
- Peak hold. Catches the loudest moment of a nap, a feed, or the neighbor's party so you don't have to stare at the screen.
- Session timer. Watch how the noise changes over minutes, not just the instant reading.
- Share a reading. Export the result as an image to send your partner, daycare, or landlord.
- No account. No subscription tricks. The core meter is free and works offline. One small one-time purchase removes ads.
How it works
- Tap Measure and allow microphone access.
- Place the phone where the baby sleeps.
- Read the live level and the session peak. Nurseries are calmest under about 50 dB.
