Wind turbines make noise. People are concerned about infrasound. Infrasound is a low-frequency sound that humans cannot hear.
Scientists studied this. They found that infrasound does not cause harm. Sometimes infrasound even helps to sleep better. But this may be a coincidence.
Audible noise causes more concern. Noise disrupts sleep and health. Sometimes noise can affect the heart. But this is not certain.
Infrasound is not dangerous. Audible noise affects people. Scientists say that theories are part of science. But they are not always correct.
It is important to listen to people. When people express their concerns, there are fewer problems. Wind turbines should be located in areas with fewer inhabitants. Offshore wind turbines are also a good option.
