Abstract
A method of identifying an operating parameter of a wind turbine that contributes to the generation of tonal noise. The method comprises acquiring operating parameter data associated with a plurality of operating parameters of the wind turbine. The operating parameter data comprises a set of values for each operating parameter of the wind turbine. Noise data is also acquired that includes tonal noise produced by the wind turbine and is synchronised with the operating parameter data. The noise data is then binned with respect to a set of operating parameter values of a first operating parameter, and, for each of one or more of the bins, the noise data in the bin is analysed with respect to a set of values of a second operating parameter. The method then determines if there is a relationship between the second operating parameter and tonal noise produced by the wind turbine based on the analysis.
