calmness counter measure classroom noise levels

Measure the noise level of your classroom with the Calmness Counter

This incredible tool measures the actual noise level of your classroom and displays it on a gauge from green to red.

It’s a great way to visually show pupils what level they’re working at compared to your expectations. You can adjust the sensitivity of the tool to suit the activity, e.g. working in silence or large groups.
