What is Classroom Noise Meter?
Put this on the smartboard and the class can see its own volume: a ball that grows with the noise, a face that goes from happy to wincing, and a red line you set for “too loud”. Stay over the line for a couple of seconds and a short alarm sounds. The Quiet challenge mode counts how many seconds the room stays under the line and keeps the best streak, which turns silent reading into a team sport.
The level is relative to your device’s microphone (not real decibels), so set the line while the class is working at the volume you want. The sound never leaves the device: nothing is recorded or sent.
How to use a classroom noise meter well
A noise meter works when the class can see it and owns it. Put it on the board, set the too-loud line together at the start of a task (“this is our group-work volume”), and let the face do the nagging. The alarm plays only after the room has stayed over the line for a couple of seconds, so a single laugh does not set it off.
Quiet challenge
Switch to Quiet challenge for silent reading or tests: the counter shows how many seconds the room has stayed under the line and remembers the best streak. Classes compete with their own record, not with each other.
Setting the levels
The reading is relative to your device’s microphone, so use the sensitivity slider once: raise it until normal working noise sits around 40–50, then place the too-loud line at 60–70. A laptop on the desk and a phone on the board will read differently; set each once.
Privacy
The microphone feeds a live level meter and nothing else. No audio is recorded, stored or sent anywhere, and the microphone is released when you tap Stop.
