How we protect your classroom
The Class Calm Meter is designed to be 100% safe for classroom use.
Because this is a free, standalone tool, it operates differently from our main TrackEDU platform.
Microphone & Audio (Zero Recording)
To measure sound levels, your browser will ask for microphone access. We never record, listen to, or transmit classroom audio. The sound levels are processed mathematically in real-time directly on your computer's browser, and the audio data is instantly discarded.
Data Storage (100% Local)
This tool does not connect to a database or a server. Any settings you change or points you track are saved locally in your own browser's cache. If you clear your browser history, the data disappears.
Student Privacy (No Names Collected)
We do not collect student names, email addresses, or any personally identifiable information (PII) to use this free tool.
100% Classroom Safe âĸ No Recordings âĸ No Cloud Storage âĸ No Personal Data
How to Use the Free Classroom Noise Meter
TrackEDUâs Class Calm Meter is a zero-setup, free visual sound tracker designed explicitly for modern classrooms and interactive smartboards. By using real-time microphone diagnostics directly inside your browser framework, it helps students visually self-regulate their speaking volumes during group projects, quiet study blocks, and collaborative classroom tasks.
Key Features for Classroom Management:
Gamified Milestones: Students earn continuous points and unlock up to 30 custom character milestones the longer they maintain a healthy, productive room volume.
Adaptive Sensitivity Calibration: Instantly optimize the microphone threshold to match a small breakout space, a standard elementary classroom, or a large lecture hall environment.
100% Privacy Secure: Built with strict data privacy protocols. Audio frequencies are calculated locally in the browser cacheâno cloud servers, voice recordings, or student data collection required.
