App Description
Noise meter & sound alarm that alerts you the moment a room gets too loud.
Noise Monitor is a real-time noise meter and sound level alarm that alerts you the instant a room gets too loud. Set your decibel (dB) limit, press start, and get an instant alert when noise crosses it — perfect for classrooms, sleeping babies, snoring, and quiet offices.
Unlike the old "too loud" sign, Noise Monitor watches the sound level for you and reacts automatically — with an alarm, vibration, screen flash, or a silent notification.
WHY YOU'LL LOVE IT
- Live decibel meter with a clear, easy-to-read gauge
- Set any noise threshold — the app remembers it
- Instant alert when sound goes over your limit
- Auto-stops when the room goes quiet again
- Runs in the background, even with the screen off
ALERTS YOUR WAY
