Noise calculations in cfx

Is it possible to show the amount of noise created by the fan in my model?. Which method can i use to display?
Which expression can i use?
I want to analysis how much noise is produced if my fan speed increases?

There is a Fan Macro in CFD-Post to evaluate noise production.

Hi,
It will be easier to go to basic thumb rule methods and see how noise increases with speed. I am not sure what kind of simulation your are doing, but if you are doing at simulations with 'basic mesh and numerics' any data you would get would be no-where near accurate.
