About this site

Allow microphone access and a box of colourful balls reacts to the sound around you: louder means higher. Made for quieting classrooms, great for whistling at.

When to open it

A visit takes a few minutes. It works on phones as well as computers, and it's silent, so it's safe at work or in class. Best for all ages and making noise.
