Sound Meter

Sound Meter is an app that lets you measure the noise level in your surroundings using the microphone in your Android device. The app will show you the magnitude in decibels and a reference as an example (the usual level in the street, in a quiet office, etc.). The magnitude shown, although probably not exact, is still very accurate.

Sound Meter has just two buttons: one to start to measure the noise level and the other to change the look of the meter. The app also displays a graph that will give you a visual and easy-to-understand representation of the noise around you.

Sound Meter is a very simple application that can be very useful, especially when you want to prove that the music is really too loud.
