Aero-acoustic noise generated by wind turbines are one of the major challenges. Noise from wind turbine equipped with a brimmed diffuser is investigated. A computational aero-acoustic study using the hybrid method is introduced. Effective parameters are studied such Wind-Lens shape, brim height and speed ratio. The optimal shape has a moderate power coefficient and the less noise generation.
