1. 1. Computational sound propagation models: An analysis of the models Nord2000, CONCAWE, and ISO 9613-2 for sound propagation from a wind farm

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Jôse Lorena Guimarães da Silva; [2017]
   Nyckelord :Nord2000; CONCAWE; ISO 9613-2; noise propagation; noise wind turbines.;

   Sammanfattning : The recent goals from some countries to become renewable energy based and reduce carbon dioxide emissions have caused the wind industry to grow. Together, the size of the wind farms and the noise emission have grown, while the noise emission regulations have to be fulfilled. LÄS MER

3. 2. Assessment of noise prediction methods over water for long range sound propagation of wind turbines

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Lukas Mylonas; [2014]
   Nyckelord :Wind energy; Sound; Noise; Offshore; Helmholtz; Partial Differential Equation; Low-Level Jet;

   Sammanfattning : Wind turbine noise is a re-emerging issue in the wind industry. As the competition for sites with good wind potential on land is rising, offshore projects in coastal areas seem as a reasonable alternative to onshore. LÄS MER
