Ambient Soundscape Assessment of Wind Parks

The potential conflicts between wind parks and the public are enormously enhanced after a rapid increase of wind parks. Assessment and management of environmental noise have played a vital role in the reaction of people concerning wind parks. This study uses an aural-visual preference survey to systematically investigate effects of background soundscapes and non-aural factors on annoyance toward wind parks. Visual and acoustic data were captured from seven German rural wind park sites. Laboratory experiments were then carried out with 40 participants to investigate the perception of the wind parks in rural areas. The tests consisted of three parts: 1) visual-only condition, 2) aural-only condition, and 3) combined aural-visual condition. Participants were immersed through google cardboard in laboratories using virtual reality technology to evaluate properties of sound and visual environment. Results suggest that the annoyance of wind parks strongly correlated with sound level ambient wind parks. However, the visual information did not demonstrate substantial effects on the people’s opinions of wind parks. Further results show that the soundscape ambient wind parks associated with factors including "calmness/relaxation", "naturality/pleasantness" and "diversity." Additionally, "calmness/relaxation" and "naturality/pleasantness" were found to have a strong impact on the evaluation of wind park landscapes.
