Claim 8:
9. A control device for controlling a wind turbine, the wind turbine comprising a hub having at least one blade with at least one an add-on member which is actuated to alter aerodynamic properties of the blade, wherein
the control device is configured to acquire a target noise level; and
the control device is configured to control the at least one add-on member of the blade such that an actual noise level caused by the operation of the wind turbine is equal to or below the target noise level; wherein
the control device is configured to control the at least one add-on member such that a power generation of the wind turbine is maximum, while the actual noise level caused by the operation of the wind turbine is maintained equal to or below the target noise level.
