Aerodynamic sound is generated as a result of the movement of vortices, or of vorticity, in an unsteady fluid flow.
These serrations can be found on the trailing edge of the rotor blades and serve to reduce the aerodynamic sound power level overall.
Aerodynamic sound is related to the intensity of fluctuating pressures/velocities and their structures (coherent motion) according to acoustic analogies [11, 13, 22].
