Sound Level Meters
Sound levels can be measured with a sound pressure meter, most often simply called a sound meter. A sound meter contains a microphone, amplifier circuit, and filter circuit, as well as a detector and display in the form of a moving coil type of instrument or a digital display. In addition, a sound meter can be equipped with some form of computational function, so calculations can be performed on sound levels recorded over a time period. There is thus a differentiation between sound pressure meters and integrating sound pressure meters.
