DR-SoundMeter is a precise noise measurement tool for Android. DR-SoundMeter displays real-time decibel levels, stores readings, and supports calibration. DR-SoundMeter offers A-weighted and C-weighted measurements for accurate assessment of environmental sound, suitable for monitoring workplace noise, home sound levels, or live events.
Key functions
DR-SoundMeter provides a real-time sound level readout with peak and average values. It includes A-weighting and C-weighting filters with selectable sampling rates and offers calibration control to adjust measurements to a known reference. The app supports min, max and hold functions and shows a simple graphical history for short-term trends. Sessions can be saved and exported as CSV for further analysis.
Usage and accuracy
DR-SoundMeter relies on the device microphone and is intended for general monitoring and non-regulatory assessments. For legal or professional compliance testing, use a calibrated sound level meter. Regular calibration against a reference source improves consistency of results when using the app.
