The invention provides a method for controlling noise of wind turbines in a windfarm. Measured weather data measured noise data are obtained (O_WND) from a plurality of sensor nodes arranged at different positions in relation to the windfarm. Further, weather conditions (O_W_WT) are obtained at least at one wind turbine, e.g. from sensors/predictors in the wind turbine. The noise and weather data from the sensor nodes and wind turbine(s) along with distances (D) between at least some of the wind turbines and at least some of the sensor nodes are used to train a learning algorithm. Further, the learning algorithm is used to predict noise (P_N) at a position of one of the sensor nodes based on measured or predicted weather conditions at the windfarm. Next, extrapolating (EX_N) the predicted noise at said position of one of the sensor nodes to a predicted noise at a point of interest in surroundings of the windfarm. Further, changing mode of operation (C_M_O) of one or more wind turbines of the windfarm based on the predicted noise at the point of interest, especially if the predicted noise exceeds a noise limit for the point of interest P_I. The method allows compliance with noise limits e.g. by slightly re-orienting one or more wind turbines to reduce noise, if it is predicted that a noise limit is exceeded, and this only costs a slightly lower than optimal energy generation in a limited time period.
