The amount of wind power plants has increased considerably over the last years in Spain, since it provides clean and renewable energy. The purpose of this paper is to study the environmental effect ofsuch power plants from an acoustics point of view, and how this has evolved over time. We have performed acoustics measurements in three different wind power plants built in the Castilla y León community in different years (2000, 2002 y 2006). We have performed the acoustics map of the surroundings and we have studied the emission spectrum. From the experimental results it can be seen that the emitted noise is basically stationary and that the global level (LwA) standing at the bottom of the aero generator remains below 70 dBA. It has also been observed that the oldest installations have higher noise emissions in spite of their smaller size and power capacity. This leads us to the conclusion that both energetic and acoustic performance of wind power plants installations have improved over the last years.
