Abstract:
A method of adapting noise emission configurations of plural wind turbines, the method including: determining total wind turbine related noise levels at plural locations; determining, among the plural locations, a critical location having a most critical, in particular highest, total wind turbine related noise level; if the most critical total wind turbine related noise level is above a noise threshold: reducing the noise emission configuration of a wind turbine having the highest noise to power impact ratio, is provided.
