Sound Meter dB uses the microphone only to calculate approximate sound levels on your device. The app does not record, save or upload audio.

Important:
Measurements are approximate and depend on the device microphone, calibration, distance and environment. This app is not a professional sound level meter and should not be used as a certified measurement device.
