| contents | Prediction of noise from wind turbines: a theoretical and experimental study Carlos Alberto Echeverri-Londoño Alice Elizabeth González-Fernández Ingeniería ISO 9613 Part 2 noise propagation Wind turbine noise Several noise propagation models used to calculate the noise produced by wind turbines have been reported. However, these models do not accurately predict sound pressure levels. Most of them have been developed to estimate the noise produced by industries, in which wind speeds are less than 5 m/s, and conditions favor its spread. To date, very few models can be applied to evaluate the propagation of sound from wind turbines and most of these yield inaccurate results. This study presents a comparison between noise levels that were estimated using the prediction method established in ISO 9613 Part 2 and measured levels of noise from wind turbines that are part of a wind farm currently in operation. Differences of up to 56.5 dBZ, with a median of 29.6 dBZ, were found between the estimated sound pressure levels and measured levels. The residual sound pressure levels given by standard ISO 9613 Part 2 for the wind turbines is larger for high frequencies than those for low frequencies. When the wide band equivalent continuous sound pressure level is expressed in dBA, the residual varies between −4.4 dBA and 37.7 dBA, with a median of 20.5 dBA. 2019 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43065097005 https://www.redalyc.org/journal/430/43065097005/ https://www.redalyc.org/journal/430/43065097005/html/ https://www.redalyc.org/journal/430/43065097005/43065097005.epub https://www.redalyc.org/journal/430/43065097005/movil 10.17533/udea.redin.n90a04 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.90 |
