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
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.
