John (and Group):
Sorry not to have further clarified this point in my original posting. I
am indeed interested in simulating the noise generated by fans (primarily)
and other sources within a design. Perhaps the most familiar application
is for a 2m tall telecom frame that will need to meet the requirements of
GR-63 for NEBS. I'm fairly certain there are similar requirements in ETSI
300 019, but I'd have to check. We're also seeing other acoustic specs
that are similar in application for other designs ranging in size from a
"pizza box" (~half the height of a desktop PC) to custom medical or other
equipment.
Our approach to date was to be as prudent as possible in the original
design with respect to acoustics and filtering on our fans and make any
modifications as needed once protos were available to measure the actual
performance. Our mechanical engineering group is interested in taking a
more deliberate approach in the future, if it's reasonable to consider
doing so.
I'm assuming from the lack of other responses that it is either my lack of
clarity in this respect or the fact that this may not be done elsewhere
that I haven't heard anything. Hopefully, I've alleviated the first option
with this further explanation.

What exactly is it you are trying to simulate? Acoustic noise from fans
and/or motors? Performance of a built-in loudspeaker?
