Disclosed is a method enabling a wind energy system to stay within noise emission limits. First of all, the inventive method consists in reducing the rotational speed of the turbine rotor as soon as set values are reached in terms of sound level, wind speed, direction of the wind or time of day. The second part of the inventive method consists in installing wind turbines whi ch do not have a reduced speed on the side of a first wind turbine which is sheltered from the wind, whereby said first turbine has a reduced speed.</SD OAB>
