Can cause wind turbines sleep disturbance and headache? Discuss this question for years, not only researchers, but also local residents from wind turbines. Numerous studies give the all-clear. However, Doctors see this analysis part is critical. So, Thomas Carl Stiller by the working group “Doctors for Immission protection”.
Headaches, heart palpitations, anxiety, fatigue: All these complaints leads to a residents of a wind power facility in the Hanover area on those system. He submitted, therefore, against the Producer an action in the district court. The " reported;Frankfurter Allgemeine Zeitung". So he is not the only one who is fighting now against wind turbines. Also in Itzehoe, a local resident complained: His family suffer due to the infrasound of the plants, sleep disturbances, dizziness, and Nausea.
The district court of Itzehoe had dismissed the case initially, it now again. Also in science there is a divergence of views on a possible connection between wind turbines and complaints of local residents. In southern lower Saxony Doctors, which explicitly warn against the health effects of wind turbines, in the working group " have;Doctors for Immissionsschutz" together closed.
One of their members, Thomas Carl Stiller. He is a PhD biophysicist and a General practitioner with a practice in Adelebsen and in Uslar (lower Saxony). There he treat regular patients from all over Germany, who complain of insomnia or a buzzing sound in the ear, pressure and feelings of anxiety. "Many do not know where the complaints come from, but remember: If you are not home, they sleep besser", watched Silent. He is convinced that wind damage on wheels the health.
Infrasound is not audible and therefore not harmful?
A future in noise pollution, to exclude, by competent authorities prior to the construction measurements. You notice that the wind turbines will be far enough away so that the residents only, a sound of a maximum of 20 Hertz (so-called infra-sound) – very close to harassment. Because man can not hear such a weak sound. Consequently, he could not feel affected by.
Doctor Thomas Carl Stiller sees in this acceptance of a Measurement and a mistake. The measurements are performed mostly Outdoors. It houses a reinforcing effect of the sound body, says Stiller. You to take sound from the ground and reinforce him. The harder and denser the soil, the worse it is. Silent calls an example of one of his patients that could only sleep on the balcony – so the Free – well. Apparently, the sound is lower there than in his bedroom.
On the other, sound can damage waves below 20 Hertz very well to the body, is Silent for sure. He refers to a study by Christian Vahl, the Director of the clinic for heart-, thoracic – and vascular surgery in Mainz. This was discovered in a series of experiments, the performance of the heart muscle may weaken cells under infrasound of up to 20 percent.
"There are already some scientific papers that show that it is in the area of the technical infra-sound changes at the cellular level gibt", stressed Silent.
Sleep lack, head and chest pain, heart palpitations, and hearing impairment
Also, the acoustician Stephen Cooper confirmed symptoms such as sleep-lessness, headache, and chest pain, heart palpitations, and hearing impairment in connection with wind turbines. He observed over a period of nine weeks, a wind Park in the Australian Cape Bridgewater with six local residents, who lived between 650 metres and 1.6 kilometres removed from the wheels.
The special feature: The researcher had the opportunity to stop the wind turbine again and again, completely. The residents led daily diary of your complaints. Cooper noted that this occurred especially when the wheels were in operation, and infrasound sent out.
Complaints are a figment of our imagination?
But, there is a direct connection actually exists? Some scientists suspect: the residents, the complaints are only because they have a General aversion to wind turbines. This Thesis finds, in fact, also in scientific Work. So about canadian and American writing-American explorers 2014: It should be possible, "that part of the population annoyed (or other health effects reports), even if the noise limit values are adhered to werden". Behind it is the subjective attitude and expectation of local residents could be stuck. Say: Who doesn’t like wind turbines, is located like you to bring him to the bedroom and sleep might actually be bad.
Country doctor Thomas Carl Stiller is convinced that his patients imagine their complaints only. "People invent the nicht", he says. He treated patients who were originally proponents of wind power plants, wind parks are planned or have owned. "Also it has taken." What all of these patients had in common: you’re not going away, the symptoms disappear.
Further research is needed to clarify the risks
Ten to 20 percent of the people living near wind turbines complain of sleep disturbances and other nuisances, estimates of Silent. In addition to the infrasound other effects of wind could interact with the wheels on the health of local residents: about electromagnetic fields, low frequency noise, pressure waves, or shadow flicker, caused by Rotating the blades. The latter could trigger some people to have epileptic seizures. Sufficiently these risks were not explored, but still.
Silent calls, to measure the load by means of wind wheels in the future, a potential damage for local residents to exclude. For one, measurements should be carried out within residential buildings instead of Outdoors because of the noise can be higher. For another, readings of eight Hertz should be taken into account, and even such low sound waves can be avoided.
How they affect the human body actually negative, need to show more research.
