Modeling and numerical approaches are favored ways to investigate the mechanisms of noise generation by fans. Several approaches are conceivable, from the simpler band-octave correlation to the costly and technically challenging aero acoustic computing.

In an industrial context, a mid-way approach, relying on experimental data to define the acoustic source term, and on well known computational method to propagate it, is still of interest.
