摘　　要：Four types of axial fans noise energy are measured and compared with prediction byvortex sheddying model(T.fukano). A correct factor is advised in case of large hub rotor ormore blades and big assemble angle.Four types of axial fans noise energy are measured and compared with prediction byvortex sheddying model(T.fukano).
