Keep Your Classroom Quiet and Focused

Managing classroom volume during independent work or group discussions is essential for learning. The TimerBox Classroom Noise Meter gives teachers an intuitive visual sound level gauge that reacts dynamically to ambient room noise.

When volume rises into the red zone, the meter triggers a clear visual "Too Noisy" alert, giving students immediate self-regulation feedback without the teacher having to raise their voice.

Launch the noise meter on your classroom computer or smartboard.

Observe the dynamic decibel readout and color-coded volume gauge.

Set clear expectations with students (stay in the green zone).

Watch students self-regulate whenever the gauge turns yellow or red.
