About Noise Meter
The Scholi noise meter reads the room through the device microphone and shows the level as a bar on the board. A challenge mode asks the class to hold it in the green for a set number of minutes.
Common questions
How does a classroom noise meter work?
It reads the room through the device microphone and shows the level as a bar on the projector. Nothing is recorded or stored — the meter only displays the current volume.
Does the noise meter record audio?
No. It measures volume live to draw the bar and keeps no recording. The microphone permission is used for the reading only.
