How does Simcenter calculate the acoustic results in a 1/3 octave band?


Hi everyone


I wonder how acoustic results such as radiation power or transmission loss are calculated as a 1/3 octave band.


for example....


1/3 octave band frequency are


Lower   Center  Upper

89.1      100     112

112       125     141


5623     6300   7079


If I calculate the transmission loss as 1/3 octave,


does Simcenter calculate all frequency range and  average ??? Or is it calculates only the center frequency?


The results for 1/3 octave band and 1/3 center frequency are very similar and I ask your opinion.
