1. A method of adapting noise emission configuration of a plurality wind turbines, the method comprising:
determining total wind turbine related noise levels at a plurality of locations;
selecting a critical location from the plurality of locations that has a highest difference between the total wind turbine related noise level of a considered location and a noise threshold for the considered location, among all of the plurality of locations;
determining that the total wind turbine related noise exceeds the noise threshold;
selecting a wind turbine from the plurality of wind turbines that is closest to the critical location and has a highest noise to power impact ratio for reducing a noise level at the critical location;
reducing a rotational speed setpoint of the selected wind turbine; and
diverting a main noise radiation of the selected wind turbine away from the critical location introducing a yaw offset which yaws the selected turbine.
