noise level in duct?

Can anyone help me to find the noise level in a duct through CFD analysis. It would be helpfull, even if you can tell me which parameter i should look for to compare the noiselevel in two ducts.

Remove the mean and then calculate the RMS. Most people would then express the level in dB referred to 20e-6Pa RMS.
