Quiet Classroom - Noise Alarm

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.
