Tuning surface vibration into noise

Hi All,

I'm doing some work to optimise engine covers from a noise point of view. I am prforming a forced response in Creo Simulate and would like to know if there is anyway I can turn the resulting surface vibration into a quantity akin to noise. In NASTRAN we have the Equivelent Sound Power calculation. Is there something like this in CREO ? If not could I raise an enhancement request.
