Wind turbines are known to result in two types of noise: the common "swishing" sounds caused by the blades and known technically as Normal Amplitude Modulation (NAM), and rarer "whumph" noises known as Other Amplitude Modulation (OAM), the cause of which has to date been uncertain. However, new research to be published today ...identifies the cause of OAM noise as sharp changes in wind speed and direction. The report concludes that sudden changes in wind speed and direction can on occasion lead to a partial stall of a turbine, resulting in the "whumph" noise.
Internal energy department emails released following a freedom of information request show the lobby group met ministry officials, after which it was assured that “the majority of R-UK’s input” was “reflected in the guidance”. Both the Government and the report’s author said last night that RenewableUK had not influenced the advice, but the emails raise new questions about the Coalition’s openness over its wind farm policy.
Giving evidence on behalf of the residents of nearby Daffy Green, Lee Hoare explained to the inquiry how, according to her research, the closer the turbines are together, the greater the noise they will generate. Dr Hoare said: “Noise impacts have been understated in this application.
"Turbines likely to be proposed in the midlands are not of the scale normally proposed on-shore in Ireland and as noise impact is not a consideration for off-shore tribunes, noise modelling and prediction for the turbines is relatively untested. "Consequently a precautionary approach should be taken to new turbines of this scale in proximity to noise sensitive locations," the submission stated.
West Devon Borough Council sought the advice of independent experts to assess the merits of a noise condition imposed upon the Den Brook Wind Farm, but the findings did not fall in favour of the applicants, Renewable Energy Systems Ltd (RES) who propose to build the wind farm in the Den Brook valley between Bow, Spreyton and North Tawton.
Dr Taylor uses "annoyance" in its medical term. She states, "Annoyance is recognised as a critical health effect, and is associated in some people with stress, sleep disturbance and interference with daily living." She says symptoms such as, "...headache, irritability, difficulty concentrating, fatigue, dizziness, anxiety, and sleep disturbance, are often described in relation to annoyance".
"It is generally accepted that the primary effect of low frequency noise on people is annoyance. Annoyance is recognised as a critical health effect, and is associated in some people with stress, sleep disturbance, and interference with daily living." ...Low level noise from wind turbines, in particular the "audible modulation of the aerodynamic noise", was more likely to cause "annoyance" than similar levels from other sources.
"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."
The group of nine residents also told Westhoughton Town Council they were not consulted by the school about the plans for the turbine. ..."It has caused so much disruption to our lives on a quiet cul-de-sac. My own thought is it should be removed as we were not consulted in the first place.
Mrs Siddell, 69, who has had serious health problems in recent years, describes the Hadyard Hill wind farm they face as a "nightmare", and sometimes retreats to the lavatory to escape its effects. ...According to Struan Stevenson, the Conservative MEP, the Siddells are not alone, and the Scottish Government's drive for more wind farms is "blighting" lives across the country.
In Ireland, for example, a court case is pending involving seven families from Banteer, Co Cork and the wind energy company Enercon. The Banteer families claim living near a wind farm has destroyed their quality of life.
A study of the Supreme Council of Health (CSS) of Belgium shows that wind turbines can cause sleep disorders in people who live nearby. CSS has issued several recommendations such as taking into account the noise level of the turbines.
The local authority is set to publish new stricter guidance to ensure that wind farms, solar panels, heat pumps and other energy-saving technologies which could come forward in the forseeable future are built in the right place and cause minimum disruption.
Unlike other forms of variable noise, however, such as railways and aircraft, it [turbine noise] can continue for very long periods at a time. The nature of the noise - a rhythmic beating or swooshing of the blades - is also disturbing. UK noise limits permit turbines to be built so close to houses that sleep impacts and associated health effects are almost inevitable.
The households have complained that the noise from the turbines, which have an overall height of around 100 metres, has turned their lives upside down and made their lives unbearable. The constant pulsating noise has led to sleep deprivation and is impacting on the health of those living close by.
A number of residents nearest to the wind farm on Høg-Jæren are struggling with poor sleep, headaches, and other complaints. They believe the cause is the constant swishing sound and turbine roar from the wind turbines put into operation in 2011.
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.
The Danish Parliament favours the wind industry to a degree where the constitutional state is weakened. Ida Auken, Minister for the Environment, is so indifferent to facts that in a consultation she delivers 38 wrong answers, including the information that wind turbine noise does not disturb more than noise from any other source, and that the regulations are stricter for wind turbine noise than for any other noise.
I realized I had a story that was bigger than just the effectiveness of wind energy. You can like it or you can hate it-that isn't the point. What this is about is government and business rushing ahead with new technology without ever making sure it's safe. A car manufacturer would never get away with releasing a new model without extensive safety tests. Same goes for food, appliances-anything. And yet these machines just kept going up, and up, and up.
"This is a giant experiment and without an enforceable noise condition Methil residents are being sacrificed as guinea pigs." Korean giant Samsung Heavy Industries will build the three-bladed 7MW test turbine 48 metres into the Firth of Forth, at 196 metres high.
