A long-term study conducted by the Technical Research Institute of Finland (VTT) investigated whether infrasound produced by wind turbines is hazardous to the health of local residents. The study was started in August 2018 and will end with the final report in June 2020. The reason for conducting the study is that local residents complained of physical symptoms that they associated with the wind turbines and possible infrasound exposure.
The German Wind Energy Association (BWE) is pleased that there is now scientific proof that wind turbines do not have a negative impact on the health and health status of citizens. In the studies conducted, no reactions to the autonomic nervous system due to infrasound exposure could be measured. The results of the study indicate that the symptoms in people living near a wind turbine are due to a so-called nocebo effect, a negative illusory effect on health (analogous to the "placebo effect").
The Finnish long-term study consisted of three parts. First, a long-term measurement was made of the sound in residential buildings located near wind turbines. Second, residents were interviewed about the situation and their symptoms. Numerous hearing tests were also carried out. Other participants in the study include the Finnish Institute of Health and Welfare (THL), the Finnish Occupational Health and Safety Authority (FIOH), and the University of Helsinki. The long-term study was commissioned by the Finnish Government's Analysis, Assessment and Research Activities.
