“The prevalence of AM has not been widely reported either in Australia or worldwide, although it’s well known that it results in increased annoyance in listening tests – and has also been cited in complaints from residents living near wind farms,” says Dr Hansen, who led the study. An audible indoor low-frequency tone was amplitude modulated at the blade-pass frequency for 20% of time at 2.4km. Audible AM also occurred for a similar percentage of the day over a broad range of wind farm power outputs of between 40% and 85% of total capacity.
The report's authors, led by research fellow Kristy Hansen, said the findings "have important implications for possible sleep disruption" from wind farms, particularly in quiet rural areas, and further work was warranted. More research was also needed to determine the year-round prevalence of audible wind turbine pulsing, as well as to quantify the extent to which people find the noise annoying, the report said.
“Up to now, resident complaints have been largely ignored by the Ministry. The documents we received showed the response rate had actually declined, and the Ministry did not seem prepared to take any action at all against the wind power operators, who are classified as the ‘Client’ in Ministry documents.
In addition to the company, board members heard from residents, including Nicole Valliere, who purchased the house immediately next door to the Pacheco property for $925,000 in March. Valliere told board members she was not aware of the turbine plans until after the sale closed and would never have purchased the property if the information was available. “We had no idea this was happening,” she said. “We never, ever, ever would’ve purchased our home.”
I am starting to wonder if a mystery noise around our house which drove us mad for months comes from the same box of tricks as wind farm turbines. A public petition raised in Scotland is trying to force the UK Government to investigate claims mysterious acoustic activity around wind farms is making people ill.
A Galloway resident has launched a petition calling for the full health implications of wind farms to be investigated before any more are built. Paul Swift said: “Thousands of people are living within 20 kilometres (12 miles) of a wind turbine and they may be suffering from health issues created by “infrasound.”
One of those conclusions is a clear link between medicine use and noise levels from wind turbines, said Aslak Harbo Poulsen, a researcher with the Danish Cancer Society. “Our studies have found that there is, certainly amongst older people, a link between wind turbine noise that can be measured outdoors and the likelihood of using a prescription for medicine to treat depression or difficulty sleeping,” Poulsen said.
A public hearing for Vineyard Wind’s proposed undersea cables that would run through Edgartown waters was cut off abruptly after several heated exchanges at a Martha’s Vineyard Commission meeting Thursday night.
A group of seven wind turbines in Johnston was just turned on in January, yet they’re already causing some blowback from neighbors across the city line in Cranston. "It's a little unnerving that all of a sudden, 519-foot structures can end up right near your home, and no one knows anything,” said Renee Petrone, who lives in the Alpine Estates neighborhood of Cranston and can clearly see the turbines from her home.
Moreno-Caballero calls for even more stringent noise limits at night: “An outdoor limit of 45 dBA during the nighttime may not be sufficiently protective if residents have open windows, a condition that may occur during the summer and as a result outdoor limits should be between 40 dBA to 42 dBA Leq-8-hour.” No recommendation was made for average night noise exposure of wind turbines in the WHO-2018 guidelines as currently “quality of evidence … is too low to allow a recommendation.”
In his comments, Punch voiced his concerns over low-frequency sound emitted by industrial wind turbines, commonly known as infrasound. According to Punch’s research, the turbines used in wind farm developments can have negative effects on a person’s mental and physical health.
Cranston isn’t the only Rhode Island community concerned about the impacts of siting wind turbines close to neighborhoods. Some residents of Coventry have complained of shadow flicker and noise from the 10 414-foot-tall turbines in their rural village of Greene. They say the utility-scale facility isn’t consistent with the town’s comprehensive plan and has dramatically changed the village’s long-established characteristics.
"Specifically, while the plaintiffs are outside on their property, they are confronted with irritating and unabated audible noise which significantly limits the use and enjoyment of their property and results in annoyance, along with other symptoms..." one of the complaints states. The New Creek Mountain Sportsman's Club claims its members suffer from headaches, rapid heartbeat, fatigue, hearing problems and other issues while on the hunting lodge's property.
Lancaster County commissioners voted 4-1 to increase the decibel level standard for landowners participating in a wind turbine project ...There is no change in the county noise rules for nonparticipating landowners.
This will increase the length of the blades from 41 to 43.5 metres and tip height from 111 to 113.5 metres. The company says this will improve energy yield by around 7 per cent. However, Mappleton Parish Council has objected to the plans, expressing concerns about the potential increase in noise pollution.
“We have received nine complaints about noise,” Fred Norton, town supervisor noted at the last Arkwright Town Board meeting. “I have instructed our engineer, who we hired to supervise the construction of the project, to do the noise testing.”
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."
Mr Zakula claims the constant humming drives him out of his home in the early hours of the morning to sleep in his car on the side of the road or even at his brother’s home in Melbourne. “It’s becoming unbearable and … I’m not, I don’t know what I’m going to do,” Mr Zakula told A Current Affair while he prepared his car for bed.
Below is the transcript of a news report produced by the Australian show "A Current Affair" that discusses the difficulty of living in proximity to a commercial wind energy facility. The show is only available from within Australia. The website https://stopthesethings.com/ posted the information.
