A table gives a comprehensive insight of the field indicators computed for each surface taken into account in the sound power computation. The acquisition and calculation procedures include the treatment of one-octave and one-third-octave band data as well as FFT data. The Sound Power levels are calculated for each surface and can be displayed also for the overall measurement surface with or without "A" weighting. Finally the following parameters are displayed: | ||
