Anti-noise wind turbine. A wind turbine (11) which comprises a blade rotor which activates an electric generator and control mechanisms for said rotor in which the blades (13) include mechanisms which allow the reduction of its lift on a length, measured from its tip, less than or equal to its radius R and said control mechanisms allow said lift reduction mechanisms to be activated cyclically during the passing of each blade through a circular sector S less than or equal to 160°. The invention also refers to an operation method for said wind turbine with which said lift reduction mechanisms are cyclically operated during the passing of each blade through a circular sector S delimited between two hypothetical radii located, following the direction of the blades, at 10 and 170° from the hypothetical radius at which a blade (13) reaches maximum height.
