In a method for enabling a wind energy system to stay within noise immission limits, the rotational speed of the turbine rotor is reduced as soon as set values are reached in terms of sound level, wind speed, direction of the wind or time of the day. The second part of the inventive method consists in installing wind turbines which do not have a reduced speed on the side of a first wind turbine which is sheltered from the wind so that the first turbine has a reduced speed.
