Simple and easy-to-use noise level meter app. It displays the noise level of your surroundings in decibels. ● How to use Tap the “START” button to start measurement. Tapping the “STOP” button pauses the measurement, and pressing the “START” button again resumes the measurement. Reset can be done by tapping the button at the bottom of the screen. ● Notes Smartphones are not equipped with the high-performance microphones found in actual noise meters. Therefore, it may not be able to recognize very loud sound, or there may be an error with the actual sound level meter value. Please use it as a supplementary tool only. If you have an actual sound level meter, you can adjust the value to match your noise meter by using the calibration function in the app. To calibrate, tap the +- icon in the lower left corner of the screen to display the setting screen.
