## What is 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.
