Most of the silencer manufacturer's have analysis software for noise prediction.

Try Virbo Acoustics:

I use there software regularily for noise calculations, as well as silencer selections. I believe you have to sign up for the software, but there is no cost.

Another silencer manufacturer is VAW Systems, who also have software:

Good luck.

ASHRAE HVAC Applications handbook also has a chapter on HVAC sound that is useful as well.
