Hello every one

First of all I would like to congratulate every one in the 20th year anniversary of www.cfd-online.com.
I'm using OpenFOAM for at least three months, such a great program, I used to be a fluent user but now I'm a 100% foamer
I'm working on a project were I need to simulate a flow in a HVAC system and predict the noise induced by the flow.
my problem is in this particular point, to be able to do that I need to see an example for some thing similar, I'm not talking about the turbulence or the mesh,
I need to know the best OpenFOAM version for this, the case structure (The Dictionaries that I need), and how I can post-prosses the result in Paraview.

so if any one did that please help
