Operators of the triple-turbine development in rural Buchan have been warned they face prosecution unless they take action to address a thumping, “whoomph” noise.
Gareth Roberts, headteacher of Ysgol Rhos Helyg in Rhosesmor, wrote a letter to nearby residents after they launched a petition to remove the 20-metre wind turbine they say has ruined their peace.
Residents say they are fed up with loud hammering in the middle of the night from an offshore wind farm being constructed off the east coast. An MP has called for a meeting with Dong Energy after people in Withernsea and villages along the coast have been woken by the dull thud of piling for the huge turbines being constructed just offshore. ...Villagers a mile inland were also disturbed in the middle of the night.
Residents in nearby streets have complained about the “very loud whining and whirring” noise from the spinning blades disturbing their sleep. And now engineers have been drafted in to fit a switch which allows it to be switched off during anti-social hours following enforcement action from the council over alleged breach of planning consent.
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.
'Wind Farms Noise: The sacrifice of the rural minorities' is the presentation by Mike Stigwood delivered to delegates attending the Scotland Against Spin conference, held on the 24th November in Stirling.
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.
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.
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.
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.
"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.
Britain's biggest onshore wind farm, in North Devon, could be operating well above permitted noise levels in every location where readings were taken, a new report claims.
Guy Glencross hates the sight and sound of his new ‘neighbour' - a 20-metre wind turbine, 90 metres from the front door of his rural Co Tyrone home. Night and day, he claims, the two-blade "monstrosity" assails his ears and eyes - and those of his partner Julie - so much so that they moved from their former front bedroom to the smaller one at the back when the turbine was erected in September.
The plant's operator has released data from a monitoring exercise which showed five of the 12 measured locations were noisier than Government maximums. But in a study to verify the data, acoustic specialists say the firm has not factored in an extra audible "hum" which would push all the readings above the maximum.
Dick Bowdler, a member of the IOU who is not involved in the study, said noise level limits and health effects should have been taken into account as part of the new guidance. The acoustics consultant pointed out that this is not only essential for planning a wind farm, but for compensation if it is built.
