Kuwano, S. et al. Dose-Response Relationships for Wind Turbine Noise in Japan

The 42nd International Congress and Exposition on Noise Control Engineering, Innsbruck, Austria, 15-18 September 2013

In order to obtain a base for wind turbine noise policy, a socio-acoustic survey was carried out throughout Japan from Hokkaido to Okinawa over three years (2010-2012). In total 747 responses were obtained with face-to-face interview method. The wind turbine noise was measured at several points in each site for successive five days. The LA,eq,n, which was precisely measured outdoor in a day, was taken as noise exposure. A representative exposure-annoyance relationship was drawn based on all data. The trend was consistent to those from Swedish and Dutch surveys. People at sites with sea wave sound were less annoyed by wind turbine noise than those at sites without. The effects of moderating factors such as interest in environmental problems, disturbance of landscape and sensitivity to noise were also investigated. …
