Wind turbines emit brain-disrupting ‘ultrasound pollution’ that affects people for miles around
Advocates of so-called “green” energy sources would like for you to believe that alternative methods of producing power have few, if any, drawbacks. This assertion has proven to be untrue in most cases, and wind turbines are no exception.
Since wind farms were first introduced, it has become increasingly apparent that there are many problems associated with their use, and that they are nowhere near as green as we were led to believe.
Aside from not being as efficient in terms of cost to build vs. what they actually produce in the long run, they have been responsible for millions of bird deaths, and the chemicals used in their manufacture are far from green.
For years, people who live near wind turbines have experienced a number of negative physical and psychological effects, but until recently it was unclear what was causing them. Among the reported effects are sleep disturbances and “decline in performance.”
But now, it seems at least part of the mystery regarding wind turbines and their effects on humans has been solved.
It has been theorized that “infrasound” waves created by wind turbine rotors might be the cause of the negative effects on humans, but advocates of wind energy have claimed that these low-frequency sounds are below the range of what the human ear can detect, and so the infrasound theories were dismissed by those involved in the industry.
Recently, however, researchers have proven that humans are capable of detecting sound at frequencies as low as 8 Hz, and that low-frequency sounds of the type emitted by wind turbines indeed do have a measurable and observable effect on the human brain.
Dr. Christian Koch of the Max Planck Institute for Human Development in Berlin headed up the research, which indicated that sounds considered too low for human ears to detect are still registered by the primary auditory cortex of the brain. This part of the brain is responsible for translating “sounds into meaning,” to quote The Telegraph.
The researchers also found that another part of the brain — an area associated with emotions — became active when volunteers in the experiments were exposed to sounds in low-frequency ranges which, until now, have been considered “inaudible” to humans.
