Measure sound levels, view live charts and save your decibel readings
Explore the sound around you with Decibel Meter: Sound Level. Use your phone microphone to estimate ambient noise and follow changes in real time. • View current, minimum, average, peak and maximum sound levels. • Switch between sound trend, frequency spectrum and waveform charts. • Choose A, C or Z frequency weighting and adjust time response. • Pause, resume and save measurements. Review local history and play back recordings. • Rename records and export CSV data or WAV audio through system sharing. • Adjust calibration, consult a sound-level reference and choose light or dark appearance. Microphone permission is required for measurement. Measurements and recordings are stored locally; sharing is initiated by you. Readings depend on the microphone and calibration and are estimates for everyday reference, not a substitute for a certified sound-level meter.
