About this tool

Group work and lab activities tend to get louder in stages, and by the time you notice, it's already too loud to fix quietly. This tool listens through your device's microphone and displays the room's volume as a live, visual meter students can see from anywhere in the room. When the level climbs, students start noticing and quieting down on their own, before you have to say a word. It's a good fit for stations, partner talk, or any activity where independent volume control matters more than a teacher's voice cutting through. Project it on the screen and let the room police itself.
