Symbols and specifications
- To Obtain the sound power level Lw octave by octave band the value Koct need to be added to the graph value Lp10A acoording the formula = Lw oct =Lp10A + Koct
- The correction factors Koct given are the average values over the range of DVS
- f [Hz] = Octave band in Hertz
- Koct = Correction factor in dB per octave band
