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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  2. 2. The effect on noise emission from wind turbines due to ice accretion on rotor blades

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Peter Arbinge; [2012]
    Keywords : wind turbine; wind turbines; noise; sound; acoustics; acoustic; ice; icing; ice accretion; rotorblades; rotor blades; IEC 61400-11;

    Abstract : Swedish EPA (Naturvårdsverket) noise level guide-lines suggest that equivalent A-weighted sound pressure levels (SPL) must not exceed 40 dBA at residents. Thus, in the planning of new wind farms and their location it is crucial to estimate the disturbance it may cause to nearby residents. READ MORE
