Decibel Meter: Sound Level

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.
