Free animal-themed classroom noise monitor with a virtual pet
PetSilence turns classroom volume into friendly visual feedback students can understand at a glance. An animated animal becomes a virtual classroom pet that reacts as the room gets louder or quieter while the class works toward a shared focus goal. It runs in a modern web browser, so there is nothing to install and no student account to create.
Read the classroom noise monitor guide, compare the Bouncy Balls alternative, or enable JavaScript to open the interactive noise monitor.
Set expectations for each activity with the classroom voice-level guide and its free printable voice-level chart for silent work, partner talk, group work, and presentation voices.
