The construction of wind farms often raises concerns about infrasound. People fear that it could harm their health. Scientists from the University of Tartu studied this and found that infrasound does not cause health damage.
The scientists reviewed 13 studies and found no evidence that infrasound is harmful. Some studies even showed that infrasound could improve sleep and mood. However, these results were considered coincidental.
The real problem is audible noise. Audible noise can disturb sleep and affect health. Some studies suggested that noise could also impact heart health, but the data is not yet conclusive.
Infrasound is not audible, but audible noise affects people. The scientists emphasized that hypotheses are part of science, but they are not always true. People's concerns are not always justified, but they are still real.
It is important to involve local residents in the planning process. When people feel heard, there are fewer problems. The scientists recommended prioritizing the construction of wind turbines in areas with fewer residents and considering offshore wind farms.
