How to play
- Click any of the five level dots, or use the Lower / Higher buttons to change the level.

- Press the left and right arrow keys any time to change levels without touching the screen.
- Tap Wall Display for a full-screen version the whole room can read from a distance.
Pick one of five fixed voice levels — Silent, Whisper, Partner Voice, Table Voice, or Presenter Voice — and a huge numeral, label, and background color show the whole room exactly what's expected right now. Click any level directly, use the Lower and Higher buttons, or press the left and right arrow keys, which also works great from a bluetooth clicker or remote while you're walking the room. Switch into Wall Display for a full-screen version readable from the back row. Because the levels are fixed and clearly labeled rather than an open volume meter, there's no ambiguity about what each setting means, so expectations stay consistent from group work to whole-class discussion. Nothing is recorded and no microphone is used.
Frequently asked questions
- What do the five levels mean?
- 0 is Silent (no talking), 1 is Whisper (barely audible to a neighbor), 2 is Partner Voice (heard by one partner), 3 is Table Voice (heard by a small group), and 4 is Presenter Voice (loud enough for the whole room), giving every volume expectation a consistent, unambiguous name.
- Can I control it without touching the screen?
- Yes, once the page has focus you can use the left and right arrow keys to move between levels, which works well with a wireless presentation clicker so you can adjust the level from anywhere in the room.
- Does it use the microphone to detect actual volume?
- No, this display is teacher-set rather than automatically sensed; you choose the expected level, which keeps it predictable and avoids any false triggers or the need for microphone permission at all.
