As every new power generation device of 10 MW or larger has to have an environmental license approval before building it, a methodology for Acoustic Impact Studies (AIS) was needed. This paper presents a methodology proposal to carry out AIS, taking into account the peculiarities of the Uruguayan status. Determining the area where the studies should be done, demands for the base line of sound pressure levels, predicting sound pressure levels during the operation of future wind farm and main lines for the environmental management plan are included in this proposal. Uruguayan current national guidelines to noise pollution levels are also presented.展开更多

However, even though wind farms represent environmentally friendly projects, they frequently generate public resistance. Wind turbines are socially controversial because of their visual and acoustic impacts. The aim of this work was to design a methodology for the preliminary evaluation of potential acoustic impact of wind farms. Three steps have been proposed: identification, characterization and assessment of the acoustic impact during the construction, operation and decommissioning phase. Obtained results in the studied area suggested that at a maximum power, at 500 meters of wind turbines, noise level is lower than the reference level established in the legislation. In summary, proposed methodology could help to determine and to evaluate the best location for new wind farm projects. Proposed methodology could help to determine and to evaluate the best location for new wind farm projects. Moreover, this method could be used as a consulting tool for public organizations and private institutions, being quick, concise and clear. Obtained results for the studied wind farm project suggested that almost all the area showed noise levels lower than established background noise level.展开更多
