| Abstract: | This paper introduces the ways to convent the real-time monitoring of the noise into frequency by using microphone, operational amplifier and V/F converter, which will acts as microprocessor's input signal. Then microprocessor will change it in to a DB value, which will be displayed on LED. This way is simple, high precision, so it is always used in monitoring the urban noise. |
