The acoustical model used to predict the sound generated by the centrifugal fan of automotive HVAC systems is described in this paper .It's one of the ventilation unit components, considered as main noise sources, that were modelled in an approach for automotive HVAC sound prediction based on virtual prototyping and noise synthesis. The other noise sources studied are the heat exchanger and the butterfly flap.
