Noise Card

A traffic-light voice level card for the board. It never listens.

How to use it

1. Press 1, 2 or 3, or tap a button, to set the voice level.
2. Red is silent working, amber is whispering to a partner, green is table talk or class discussion.
3. Each level also has a word and a number of bars, so it does not rely on colour alone.

Privacy. This tool never uses the microphone. It is a visual signal that you choose yourself. Nothing is stored. Nothing is sent to any server. Use the Full screen button to show it on the projector.
