\u{1F634} Not listeningOpen this page on the classroom screen and press start. The bar follows the room in real time, and the line marks the level you decided is too loud. Drag the line to where your room actually sits: a Year 3 art lesson and a silent reading test are not the same number.
It works because the class can see it. Nobody has to be told to quiet down. They watch the bar climb towards the line and settle themselves, which is a much better lesson than being shushed.
Your browser asks for microphone permission the first time. If you say no, the meter simply does not read. The percentage is a relative loudness reading for your room and your microphone, not a calibrated decibel measurement.
Learnify turns the class into a role-playing game run from the teacher's screen: points for real reasons, avatars that evolve, attendance, groups and quiz games. Pupils need no devices and no accounts of their own.
