Abstract
This report investigates the noise sources for modern three-bladed wind turbines along with the pertinent parameters in outdoor sound propagation to create an auralisation of a wind turbine. Focus has been on the effect of the different propagation parameters and sound models of a wind turbine, which is reflected in the opportunity to switch between or adjust these parameters in the simulation. In the implementation, this is carried out by various audio effects and filters, such as the chorus effect and variable filters. The simulator allows for comparison with real wind turbine recordings, which have been made as a part of the project. From the results and informal listening observations, it is found that the simulator provides a believable sound of a wind turbine. However, further work could improve the sound experience by using models of higher complexity such as modelling turbulent wind conditions giving the sound a more natural, imperfect characteristic.
