Frequently asked questions
Is PetSilence a classroom noise monitor or a noise meter?
Both. The live sound bar works as a classroom noise meter, and the pet, bouncing balls, or farm turn the same level into a friendly visual noise monitor. Levels are relative to your room after calibration, not calibrated decibels.
Can PetSilence play a sound when the class is too loud?
Yes. Turn on the alert sound next to the classroom sound meter and choose a soft chime or a gentle shush. It plays once when the room becomes too loud, then waits before playing again. It is off by default.
Does PetSilence record classroom audio?
No. PetSilence calculates sound intensity locally on the device and does not record, store, transcribe, or upload classroom audio.
Is PetSilence free?
Yes. The classroom noise monitor is free to use in a modern web browser, with no teacher or student account.
Is there a free classroom noise monitor with animals?
Yes. PetSilence is a free animal-themed classroom noise monitor: a cartoon pet sleeps while the room is quiet, looks up as voices rise, and asks for calm when the class gets too loud.
What is an animal-themed classroom noise monitor with a virtual pet?
It is a visual sound-level tool where an animated classroom pet reacts as the room becomes quieter or louder. The shared character gives students a friendly cue to adjust their voices without recording what anyone says.
Can I choose a different animal?
Yes. Pick a corgi, kitten, bunny, or panda, and switch between cartoon, hand-drawn, and felt art styles. Each pet sleeps when the room is quiet, looks up as voices rise, covers its ears when it gets too loud, and jumps for joy when the class reaches its focus goal.
Can I use bouncing balls instead of the virtual pet?
Yes. Choose Bouncing balls to use a sound-responsive ball display while keeping the same modes, timer, calibration, and rewards. You can also visit the Bouncy Balls alternative page for a detailed comparison.
Does the class keep its progress from day to day?
Yes. Choose Farm and your class pet moves onto a small farm. The class votes on what to plant (carrots, strawberries or corn), every quiet minute grows the crop, and each completed focus goal is a harvest. Harvests clear wild land to uncover treasures such as a well and a red barn, and bring little animal visitors for the class's visitor book. When a place is fully cleared, the class votes on where to go next on a valley map: an apple orchard, a duck lake, a flower hill or a snowy village. A quiet calendar shows the class's quiet minutes for each day. Noise only pauses the growing, so nothing is ever taken away. Progress is saved in this browser, with no account.
Is PetSilence a classroom noise monitor game for kids?
PetSilence uses a virtual pet, focus goals, and stars to make classroom volume visible and engaging. The teacher stays in control of the activity, microphone, thresholds, timer, and rewards.
Do teachers or students need an account?
No account is required to use the sound meter, focus timer, visual cues, or classroom rewards.
Can I show it on a classroom display?
Yes. Open it on the classroom computer, then use a projector or interactive display so students can see the shared cue. Fullscreen mode hides the page content and extra buttons so the visual, timer, and sound meter fill the screen.
Does PetSilence work on Chromebooks and iPads?
Yes. It runs in Chrome, Edge, Safari, and Firefox on Windows, Mac, Chromebook, and iPad. The browser asks once for microphone permission.
Why should I calibrate before starting?
Every room and microphone is different. Calibration helps PetSilence set sound thresholds that fit the current space.
