Bouncy Balls 🎈

The bouncy balls noise meter, but cuter

A classroom classic, lovingly remade. When your class is calm, a whole pile of pastel balls dozes at the bottom of the screen — big ones with sweet sleepy faces, dozens of tiny ones snuggled between them. As chatter grows they wake up and start to bounce, and if it gets really loud, they fly! You can even sweep your mouse through the pile to scatter them, or grab a ball and toss it. Students see their volume instantly, and the quiet-streak timer and live decibel meter (with the 85 dB safe-hearing mark) give them a reason to settle down again.

Shush Meter is free, needs no account, and never records your classroom — sound is measured live in your browser and never leaves your device. Try the other themes too: the sleeping cat your class mustn't wake, or the calm aquarium.
