The Sound Level Meter is an application that allows you to measure the noise level of a place. With it, you can find out the sound pressure level (SPL) in different parts of the room, and even in different places in the room. The measurement is made with an Audio Meter, which is a built-in microphone that can be used to convert the sound level into an electrical signal.

This application has two modes: slow and fast. In the fast mode, the application is made to run at a slow speed, which makes the measurement more accurate.

The fast mode allows you to use the microphone of your device, which gives a more accurate result.

The application has a built-in equalizer that allows you to adjust the sound level in different frequency bands.
