DanskA classroom noise meter your students will adore
Shush Meter turns your classroom's volume into something students can see. Put it on the projector, choose a theme, and watch the room manage itself: balls start bouncing when chatter grows, the kitty wakes up when it's too loud, and the fish hide until calm returns. It's a kind, playful way to teach voice levels — no nagging required.
Three lovely themes
Choose bouncy balls, the sleeping cat or the calm aquarium. Each one reacts live to your classroom's noise.
Quiet streaks
Shush Meter rewards calm instead of only pointing at noise. The streak timer counts how long the class stays under the limit — can they beat their record?
You set the limit
Silent reading or group work? Slide the noise limit to match the activity, and add a gentle "shhh" sound alert if you like.
Private by design
Sound is measured inside your browser and never recorded or uploaded. No accounts, no tracking, nothing to install.
How it works
- Press start and allow microphone access — that's the whole setup.
- Pick a theme and set the noise limit for your activity.
- Go fullscreen on the projector and let the class watch their own volume.
Frequently asked questions
- Is Shush Meter free?
- Yes! Completely free for teachers — no sign-up, no downloads, no ads interrupting your class.

- How is this different from Bouncy Balls?
- You still get a bouncy balls theme — plus a sleeping cat and an aquarium, a quiet-streak timer that rewards calm, an adjustable noise limit, gentle alerts, and a design that looks lovely on a projector.
- Do I need to install anything?
- No. Shush Meter works in any modern browser on laptops, Chromebooks, tablets and phones.
- Can the whole class see it?
- Yes — one click takes it fullscreen for projectors and smartboards.
