About the bouncy balls noise meter
Colorful balls bounce higher as the room gets louder, which kids find far more motivating than a bar. Set a limit, and the screen warns gently when the class goes over it. The microphone only measures loudness in your browser; nothing is recorded or uploaded.
Ways to use it
- Independent work time: keep the balls calm.
- Indoor recess and wet-play volume control.
- Make "quiet" a game younger students want to win.
Frequently asked questions
How do I make the balls less jumpy?
Lower the sensitivity slider. In a noisy room, a lower sensitivity keeps the balls calm until the class gets genuinely loud.
Is this the same as the Bouncy Balls website?
It’s our own free version of the same idea: a microphone-driven noise visualizer for classrooms, with no sign-up and nothing recorded.
