Experts probe if wind farms affect sleep

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."

Bald Hills Wind Farm Noise - video

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.

Wind farmn noise recorded almost 9km away

“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.

Can wind turbines disturb sleep? Research finds pulsing audible in homes up to 3.5km away

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.

Not in our backyard

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.

Shire, state must act on turbine noise

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.

Turbine bombshell

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.

Wind turbine noise exposure proven a ‘pathway to disease’

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.

Wind turbine health fears warrant study, says tribunal

“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.”

Wind farms: Farmers making a noise of their own

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.

Neighbours at odds over noisy wind farm

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.
