- Its estimate adds an assumed 100 dB offset to the microphone signal; the page explicitly says that offset is unvalidated for individual phones.
Field notes
The meter asks for microphone access, then presents estimated levels in a rolling 30-second view alongside average, maximum, and session duration. Its explanation says it adds an assumed 100 dB offset to the microphone signal and displays values below zero as zero; the page says that offset is not validated for a particular phone. It also cautions that the result is not a calibrated sound-meter reading and should not guide hearing-safety decisions.
