Bouncy Balls
Bouncy Balls visualizes classroom sound levels as bouncing balls and functions as a noise monitoring tool.

About Bouncy Balls
Bouncy Balls is a web-based classroom noise meter. It uses the device microphone to pick up sound and shows the resulting noise level as balls that bounce in response. The homepage describes it as a free tool for classroom noise management and states that it is intended for schools where students are too noisy.
The tool runs in a web browser. The homepage says it is incompatible with some browsers and recommends Chrome or Firefox. Because it responds to sound from the microphone, it only reflects what the microphone picks up in the room where it is running. The homepage does not describe any data storage, recording or sharing behaviour beyond a link to a privacy policy.
