This paper describes design and construction of a noise meter, which measures sound pressure level. The device can be set either for weighting filter A or for weighting filter C considering the characteristics of human hearing. The device also allows two modes, Fast and Slow, depending on the rate of changes of sound pressure level. It is possible to send measured data to a PC through a measuring application. The noise meter can be controlled by buttons or by voice commands.
