Currently being examined in a free-field rotation point source of acoustic characteristics; Lowson through the wave equation is derived out of the sound field formulation moving point source generated, the formula appropriate for each micro unit on the blade, then the leaves all infinitesimal Quadrature you can find the acoustic field generated by the blade movement. But to develop the blade infinitesimal point source size is a problem, and generally fan blades are not straight blade, even a great distortion in space, the simulation with a point source model prone to large errors. Further, the study is aimed at free field, but must consider the impact of centrifugal fan volute.
