Abstract(s) :

(Anglais) For 15 years the number of wind turbines installed in Europe has increased rapidly. In this framework many objections are expressed towards the sound emitted during the Wind Turbine (WT) working and its perception as a noise in the direct neighbourhood. The noise is due to aerodynamic interactions with the blades of WTs. After its propagation over several hundred meters, the noise is more or less stationary but can feature an amplitude modulation that can be very annoying for the human hearing. To understand the physical causes of this potential annoyance, some noise measurements were carried out. A lot of care is necessary to have relevant recordings of the WT noise. The measurement precautions are explained as well as the data processing to avoid the periods with a dominant background noise. Finally some results of measurement campaigns are exposed.
