The sound module does not automatically create a display. The users has to create the setups to show the sound level channels. The display below shows  typical screen for sound measurement.

We use the typical A weighting to calculate Leq and Lp, which are shown in the multimeter, bar display and recorder. Additionally, the octave or narrow band FFT is calculated. This can be achieved by adding an FFT screen and in this screen where we can define frequency weighting, such as A weighting and dB scaling.
