How does the noise meter work?

The tool uses your device's microphone to measure ambient sound levels and displays them on a visual gauge in real time.

Can I set a noise threshold?

Yes, you can set a threshold level. The meter will visually alert you when classroom noise exceeds that limit.

Yes, your browser will ask for microphone access the first time you use it. The audio is processed locally and never recorded or uploaded.

Monitor and visualise classroom noise levels with customisable thresholds and visual feedback.
