Noise meter
Press Start, allow the microphone, and the meter shows the room's volume as it changes. Set the line where the room is too loud and the meter shows the moment it is crossed. Sound is measured in this browser only; nothing is recorded and nothing is sent.

Lower for quiet reading, higher for group work. The line on the meter moves with it.
In the classroom
How teachers use it.
- Group work: the class picks its own target and watches the meter.
- Quiet reading or test time, with a visible line instead of a reminder.
- Teaching what an inside voice sounds like, by watching the level fall.
