|Abstract:||The current energy situation imposes an acceleration toward the development of techniques for the exploitation of renewable energy sources. Recent European regulations impose percentages of energy produced by more and more renewable sources. The current technological development indicates the wind energy as the renewable energy source on which we can rely more and more; this technology uses big wind turbines with nominal powers of about 3 MW. Among the main environmental problems that we have to face in planning a new wind farm, there is the acoustic impact due to the noise generated by WTG, with a particular reference to the assessment and measurement of the noise emitted at low frequencies. With this work we want to clarify both the methodologies currently used in measuring the noise emitted at low frequencies, and to estimate the acoustic insulation of the buildings envelope, of the buildings that are populated by people and that are often near the areas in which wind farms are settled.|
