Abstract: A method for of controlling audible levels of tonal noise produced by a wind power plant comprising a plurality of wind turbines is provided. The method comprises identifying a wind turbine as contributing to a level of tonal noise that is audible at a noise reception point; and adjusting one or more operating parameters of a wind turbine other than the identified wind turbine in order to reduce a level of tonal noise produced by the identified wind turbine that is audible at the noise reception point, and thereby reduce the level of tonal noise that is audible at the noise reception point. A controller configured to perform the method, a wind turbine and wind power plant comprising the controller, and a computer program which when executed by a computing device cause the computing device to perform the method, are also provided.
