According to the present invention is provided a method of control of noise emission from a wind park in operation, the wind park comprising a plurality of wind turbines. The method comprises the steps of•providing measurements of at least one wind speed and of at least one wind direction to a park noise emission emulation module including for each of two or more of the plurality of wind turbines a wind turbine noise emission model being suitable for producing a prediction of noise emission from the wind turbine as a function of at least one operational characteristic, the geographical position of each of the plurality of wind turbines, and the geographical position of at least one noise immission point,•emulating the noise level at the at least one noise immission point as a result of noise emitted by the plurality of wind turbines, and•controlling the operation of the wind park from the result of the emulation so as to prevent the noise level at the at least one noise immission point from exceeding a predetermined threshold level. Furthermore, the invention relates to a wind park.
