📈 UNDERSTAND SOUND LEVELS

Use the built-in noise reference to get a general idea of different sound environments, from quiet surroundings to very loud conditions.

The app can help you identify changes in environmental sound and understand how loud an environment is based on its measured decibel level.

📱 EASY TO USE

Open the Sound Meter, allow microphone access, and start measuring. The current sound level is displayed immediately while the graph and statistics help you understand how the sound changes over time.

🔧 CALIBRATE FOR YOUR DEVICE

Different Android phones can have different microphone characteristics. Use the calibration option to adjust the meter when you want readings that better match your environment or a known reference.
