Dear all,
I'm working with acoustic predictions originating from CFD/computer simulations, and I readily have my acoustic results represented as sound pressure levels (dB). I end up with equally spaced frequencies, from 100 to 20,000 Hz with a step of 100 Hz for instance. I need to represent my results in third octave bands, and I have some doubts on the correct methods of summing/averaging for each different band. I find plenty of resources for addition of noise sources but this is quite different I think, should it be a log average or similar?
Any help would be greatly appreciated, or if you could point me to an appropriate resource?
Thank you in advance,
Kind Regards,
Nathan
