“A new regulatory framework is required to align the approach to managing wind farm noise with the [amended] Act,” the government said on its Engage Victoria website this week. “Clear and consistent wind farm noise regulation is needed to provide certainty to industry and confidence for communities.”
Dr Micic said the latest study aimed to comprehensively review published evidence regarding the impact of wind turbine noise on the most widely accepted objective and subjective measures of sleep time and quality. ..."Nevertheless, the available self-report data appeared to support that insomnia severity, sleep quality and daytime sleepiness can be impacted by wind turbine noise exposure in comparison to quiet background noise."
The property belonging to Mr Johnson and his family will be one of three residential Waituna Rd properties to fall under the “shadow” of RES’ proposed $450 million Dulacca wind farm, with some of the closest turbines to be built just over two kilometres from his back door.
This video recording taken at the Bald Hills wind energy facility in Victoria Australia demonstrates the noise emissions from the project. The video was taken on September 26, 2018 and should be listened to with high-quality headphones. The project was constructed by Senvion and includes 52 Senvion MM92 (2.05 MW) turbines with hub heights of 80 meters and rotor diameters of 92 meters. The full 106.6 MW facility was placed in service in May 2015. This video is part of a noise compliance study conducted by acoustician, Dr Bob Thorne. Dr. Thorne found that the turbines were operating at noise levels that exceeded the approved levels and that sleep disturbance and intrusive noise and nuisance conditions existed at nearby homes. The full Thorne report can be found at this link.
“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.
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.
The Victorian Government has changed the rules around the testing of wind turbine noise at all new wind farm developments. The new regulations follow an unsatisfactory independent audit of wind turbines at the Lal Lal Wind Farm, which is under construction near Ballarat.
Wind Energy Partners say the delay is the result of extra studies on the project’s visual and noise impacts, which have been undertaken in response to community concerns. Meanwhile, the Hills of Gold Preservation group met in Nundle on Thursday night, to highlight a number of concerns regarding the 98-turbine project.
A class-action lawsuit is being planned against a local council, the Victorian government and a wind farm operator after an independent review accepted resident complaints that noise from a Gippsland wind farm was causing them harm.
Noise from a wind farm in Victoria's Gippsland is having an adverse impact on the comfort and wellbeing of residents living at surrounding properties, a new report commissioned by a local council has found.
The shire council must finally acknowledge that the neighbours of the Bald Hills Wind Farm, their own ratepayers, have a legitimate gripe under the Public Health and Wellbeing Act and support them in their attempts to get redress from the operator and the State Government. And the State Government must finally admit that it allowed the turbines to be sited too close to the existing farm houses for them not to cause a noise nuisance.
The report by Mr Smith, an expert in public health follows a botched attempt by the shire to investigate the complaints itself between May and November 2016, after which the shire produced a finding of “no nuisance” in January 2017 before telling the affected property owners that the case was closed in April 2017. But it wasn’t closed and the complainants took Supreme Court action to get a proper investigation. The matter is due to go back to the Supreme Court on November 26, two days after the next state election.
In its summary, and with unanimous support from relevant experts, AAT found that there were numerous recorded instances of wind turbine noise exceeding 40 dB(A) — a recognized threshold for annoyance/sleep disturbance. “Even if it is not audible, low-frequency noise and infrasound may have other effects on the human body, which are not mediated by hearing but also not fully understood,” the summary reads.
“That is something which we expect will be the subject of further study,” the AAT said. “For our purposes, it is sufficient that annoyance is produced, and it appears that it may be associated with adverse health outcomes. “An identification of the causes of that annoyance may allow it to be reduced or mitigated and adverse health outcomes to be reduced or avoided.”
Hawkesdale farmer Paul Lewis says noise from Macarthur wind farm, five kilometres from his home, wakes him up at night. ...“No one can do anything to really address the problems with existing wind farms. Moyne (shire council) have wiped their hands of it and don’t take responsibility, and the State Government isn’t doing anything,” Mr Lewis said.
Now with a slew of new wind farms planned around his town of Hawkesdale, 300km west of Melbourne, and impending changes to Victorian state planning policy, Mr Lewis is seriously pondering his future. “Everyone thinks these things are great, but they’re not the ones living beside them and getting woken up at night,” he said.
Huffman told commissioners the problems were worst when wind speeds were low, particularly between 6 metres per second and 10m per second. She backed the city council's position, that there should be an 8m per second threshold before the turbines kick in at night. She also said subjective assessment was a legitimate way to monitor noise.
