Once dismissed as something merely imagined by people close to industrial wind turbines, health disorders caused by infrasound are emerging as being very real.
Austrian site www.ots.at here has a press release by the Vienna Chamber of Physicians warning of health hazards from large-scale wind turbines, citing “comprehensive studies”. It calls for a minimum setback distance from built-up areas.
The OTS writes that noise from wind turbines is increasingly coming under the focus of scientific studies. Low frequency infrasound (< 20 Hz) was dismissed by wind energy proponents, but rapidly mounting evidence show the problem is more serious than first thought.
As part of the “International Noise Awareness Day” the Austrian Chamber of Physicians warns that today’s large size wind turbines have a blade diameter as large as a football pitch and a blade tip speed near 300 km/hr. They therefore create noise in the infrasound frequency range, which is known to cause health problems. Physician Piero Lercher of the Chamber of physicians: say:
Our target must be to prevent sleep disorder, psychological affects and irreversible damage to hearing from the noise such as that produced by wind turbines.”
The press release reports of increasing complaints stemming from low frequency infrasound and says studying the health impacts “is essential”.
Lercher adds that another component may be at play:
Perception disorders of persons living nearby are thought to be perhaps triggered by a ‘nocebo’ effect .”
Anti-wind energy group windwahn.de here thanks the physicians from Vienna for looking at the concerns of residents seriously, as many are ill and others are confronted by the threat of years of “acoustic torture” from proposed wind projects. Windwhn cites studies from all around the world and that it is time for Germany to wake up to this reality. The site writes:
We can no longer ignore the one third of residents in wind power regions who are sound injured and have serious health consequences!”
