Humans can only perceive sound waves over a range of approximately between 20 and 20,000 Hertz. Sound waves below 20 Hz cannot be heard by humans and are called infrasound.
Natural infrasound emitted by nature is harmless but it is increasingly being understood that infra-sound generated by wind turbines pulsates and make people who are subjected to them over extended time periods sick.
The rotating blades of wind turbines cause air pressure changes, which in turn can cause pressure on the ears and chest and lead to health issues and even serious problems like arrhythmia and vision impairment, according to a German Medical Journal.
The study's abstract states: "Noise-exposed citizens, who live near infrastructures such as biogas installations, heat pumps, block-type thermal power stations, and bigger industrial wind turbines (IWT's), show worldwide mainly a symptomatology associated with microcirculatory disorder."...<<<Read More>>>...
