The low-frequency sounds, inaudible, emitted by wind turbines are not harmful to human health, according to a Finnish study published on Monday.
This is a new study showing that the audible noise of wind turbines has no negative effects on health. The low-frequency sounds, inaudible, emitted by wind turbines are not harmful to human health, according to a study conducted for two years at the request of the Finnish government and published on Monday.
This study analyzed the effects of low frequency sound, or infrasound – emitted by the wind turbines that cannot be heard by the human ear. In many countries, a lot of people have attributed to these infrasound symptoms ranging from headaches to tinnitus or cardiovascular problems.
But the scientists say that the findings “do not support the hypothesis that infrasound (…) cause a nuisance”. “It is more likely that these symptoms are triggered by other factors such as the expected symptoms” by people living near wind turbines, according to them.

The researchers are based on interviews, sound recordings, and laboratory tests to investigate the possible effects of these sounds on the health of those living within 20 kilometres of the generators. In addition, the tests have not proven that the sounds of the turbines disrupted the rhythm of the heart, according to the same study.
