Guides for a calmer, more honest classroom noise monitor.
These pages are for teachers who want more than a toy on the board. They cover how volume competes with attention, how to match a target to silent work or group talk, how to project the four games, and how to keep the cue from turning into punishment.
RoomTone itself is the free live tool on the homepage: four projector games, no account, no recording. The library exists so the site is useful even when the monitor is off — and so every page that might show an advertisement still has a real job for a visitor.
How to use this library
If you are setting up for the first time, start with the first-week rollout and the traffic-light guide. If the microphone is the problem, skip ahead to microphone setup. If you already have a bouncing meter and want a calmer alternative, read the comparisons.
None of these guides claim certified decibels. A laptop microphone is a relative meter. Use it to hold an agreement the class can see, not to produce a number for a facilities report.
