For microphone problems, the fastest help is the troubleshooting guide. For accuracy questions, read how accuracy works. For background on the project, see about.

What to include

Device model, operating system and browser version, microphone used, and what you saw on screen (for example, the idle “--” display, a permission prompt, or an estimated dBA value). If you calibrated, include the reference level and offset. Screenshots of the live panel help, but never send audio recordings — this tool does not create them.

Response time

Email is monitored on weekdays. Most questions are already answered in the guide hub: how to use, calibration, methodology, and privacy.
