Medical and scientific evidence is increasing that not only some animals, but also humans are able to perceive infrasound below the hearing threshold. This is not surprising actually, because "infrasound is an energy," explains Prof. Vahl, "And every energy has physical effects, whether you hear it or not."
This news segment from the German television program “Hessenschau” examines how all wind turbines in Hesse in Germany must be checked because of the noise they make. THe show aired on August 8, 2018. English subtitles are by Vind-Alarm-Danmark.eu and Friends-Against-Wind.org.
The Ruhwarders are protesting against the wind farm. They know that it is long past due to protest but hope that the situation can at least be improved. Ruhwarder citizens believe theor lives have been degraded since the new wind farm in Düke was placed in service. The operator is open to discussions - and promises to improve.
“You cannot smell it, you cannot see it, and you cannot really hear it but maybe it still drives some people crazy.” This powerful news story from Spiegel TV Magazine explores wind turbine infrasound impacts on people. English subtitles added by Friends Against Wind.
How close can wind turbines be sited near back in inhabited localities? Reports of adverse health noise emissions from wind turbines in Denmark already have led to a dramatic slowdown in the pace of expansion.
"It's all an enormous swindle," says Besigheim-based auditor Walter Müller, whose job involves examining the books of wind farm companies. His verdict? A fabric of lies and deception. The experts commissioned by the operators of the wind farms sometimes describe areas with weak breezes as top "wind-intensive" sites to make them appear more attractive. "Small-scale investors are promised profits to attract them into closed funds for wind farms that do not generate enough energy," he says. "Ultimately, all the capital is eaten up."
Opponents of wind farms in the US and Canada insist that low-frequency noise generated by turbines is detrimental to human health. But in Germany, experts aren't convinced that infranoise poses a threat.
Enercon, Europe's largest wind turbine manufacturer, has a problem: The decision of the Bavarian Higher Regional Court in Munich about the wind turbine in Kienberg points out that in the E 82 turbine emits pulsed noise. Therefore to any actually measured sound level three decibels would have to be added.
From Barton, Vermont, to the German border with Denmark and from the shores of Lake Huron, to the Romney Marches of southern England, wind power advocates are fighting crosswinds from local residents. In Barton in mid-January, a referendum overwhelmingly rejected the wind power turbines that were planned near this upper Vermont community. ...In Germany, where one-third of the world's current wind power is generated, doubters have provoked a loud debate. The company that owns the grid that includes nearly half the wind-farms in Germany reported its wind farms generated only 11 percent of their capacity. The company said the winds vary so much the wind farm had to be backed 80 percent by the conventional power grid.
They introduced the world to "environmentally friendly" energy, but now some of Europe's "greenest" countries are under pressure to backtrack on wind farms as public anger grows over their impact on the countryside.
This significant research by van den Berg explains why turbine noise as far away as 1900 meters (more than 6,000 feet) is resulting in complaints by residents particularly at night. The paper concludes that noise immission predictions are not accurate and result in the understating of turbine noise levels, particularly during nighttime conditions.
This paper describes a case study in which low frequency noise (LFN) was suspected of causing disturbance in a semi-rural location close to an industrial estate. Previous attempts using conventional acoustic measurement techniques to resolve the case, or even prove the existence of a real acoustic problem, had proved unsuccessful. The study does not involve wind turbine noise directly, but the work done and resulting findings provide insight into identifying the problem of LFN and predicting annoyance.
