Abstract— By measuring sound levels, we can tell where a quiet enough or a place is contaminated by noise. Then, designers offer soundproofing solutions suitable for each location such as home or library,…

I. INTRODUCTION
Today, sound pollution is one of the social problems[1]. It significantly reduces the concentration of an individual or a group. Result, reduced work efficiency or even cause undue stress.
We introduce a method to measure noise in the most convenient way. Based on module sensor MAX4466 and cheap boards such as the Arduino, it is possible to produce a convenient sound levels meter compared to hundreds of dollars machines.
Sound level meter is an indispensable module in Smart-City projects[2]. Combined with other modules such as traffic flow measurement, one can come up with solutions to solve the above problems.
II. METHODOLOGY
A. General of sound and why to choose Arduino ?
Sound or to be more precise, sound pressure is an analog signal and if we sketch it over time, then it would be called waveform.
The analog signal is obtained from the microphone, we
