Sound Meter

Sound Meter is an app designed to measure the decibel (dB) level of the sounds around you with high precision. When you launch the app, you’ll immediately see the exact decibel reading, along with a simple reference label that estimates what that level sounds like in real life—such as loud music, a whisper, or traffic noise.

You’ll also get a visual chart showing how the dB level has changed over the last 30 seconds, so it’s easy to tell whether the environment is getting louder or quieter. If you want to improve reliability for your specific device, use the calibration option to help ensure your Android is capturing and interpreting audio data correctly.
