ClassCalm dB

ClassCalm dB helps teachers keep a class inside the right noise band without turning classroom management into another lecture. Use it to: - read live microphone level as a simple classroom dB cue - choose modes for testing, independent work, partner talk, or transitions - run a two-minute quiet challenge students can see from a projected screen - get reset prompts when the room moves above the target band - save quick room checks locally for later reflection ClassCalm is designed as a teacher-side tool. It does not record audio files, identify students, sync rosters, require an account, or upload classroom data. Microphone readings are practical classroom cues, not a certified sound-level meter.
