How does the noise monitor work?

The noise monitor uses your device microphone to detect sound levels in real time. It displays a visual meter showing the current noise level compared to your threshold.

Can I set different noise thresholds?

Yes. Adjust the sensitivity to match different activities. Set a lower threshold for quiet reading time, or raise it for group discussions.

Does it record audio?

No. The noise monitor only measures volume levels. No audio is recorded, stored, or transmitted. All processing happens locally on your device.

Can students see it on the projector?

Absolutely. The fullscreen mode is designed to be displayed on classroom projectors so students can self-monitor their noise levels in real time.

What happens when it gets too loud?

The display changes color when noise exceeds your threshold. You can also enable optional alerts to notify the class.

Does it work with all browsers?

The noise monitor works with modern browsers that support microphone access, including Chrome, Firefox, Safari, and Edge.

Can I use it during testing?

Yes. It is useful for maintaining a quiet testing environment because students can self-regulate without constant reminders.

What is the Pearl Collector?

A built-in reward shown on the widget. Every minute the room stays under your loud threshold, the class earns one pearl. The count is visible during the activity, giving students a positive, no-words signal that quiet is paying off.

Is microphone data private?

Yes. Audio is processed locally on your device and never leaves your browser. We do not store or transmit any audio data.

Why should I upgrade to Pro?

Pro unlocks unlimited cloud-saved whiteboards with every tool embedded as a widget, multi-device sync across school computer, laptop, and tablet, priority support, and 30 monthly AI credits that work across the lesson planner, rubric generator, quiz generator, and worksheet generator. You can also request new tools and we ship them within 7 days.
