The Abbott government will appoint a “windfarm commissioner” to handle complaints about turbine noise and a new scientific committee to investigate, again, their alleged impacts on human health, in a late-night deal with anti-wind senators over amendments to renewable energy legislation.

The scientist who set up the Sydney University Auditory Neuroscience Laboratory says the growing body of evidence points to the low-frequency infrasound they create directly affecting the human nervous system. ... “This is going to be an important energy source and if we’re building tons of these things in the wrong places or building them in the wrong way then we’ve got big trouble.”
The hills above Kahuku have proven to be a prime place to harness power from the wind. One wind farm has already been planted and another could go up soon. It’s a plan that have some residents concerned.

Fears over adverse health impacts caused by wind farms are being heavily scrutinised during a parliamentary inquiry into the controversial renewable energy source. The Senate select committee inquiry into the regulatory governance and economic impact of wind turbines, established last November, is due to report by August 3.
“The problem is that, in spite of the fact that you say they are the most stringent rules and regulations, people are still claiming to have health effects and annoyance and sleep deprivation. What we are trying to establish here is: what needs to be done to remedy this situation so that people - the general public; the people who are suffering - have a greater sense that they are being listened to and that there are stringent guidelines in place for the development of wind farms.”
An attorney has advised selectmen that sound limits in the town's revised Wind Energy Facility Ordinance are "pretty low" compared to others she has reviewed.
"I am usually the last person to support the creation of additional government bureaucracy but when we are directing around $22 billion towards the Renewable Energy Target (RET), the creation of a regulator would be a drop in the bucket," Senator Leyonhjelm says. "Those who justify action on climate change because of the precautionary principle will understand the need to apply the same principle to infrasound."
Proposed noise rules being drafted to regulate commercial wind turbines in Lancaster County are so restrictive they would effectively prevent wind projects being developed here, according to a Portland, Oregon-based company that wants to develop a 50-turbine farm in Lancaster and Gage counties.
Heritage's lawsuit focuses on a pair of recently-adopted Garden Township noise ordinances - Ordinance 2014-1, and a revised version called Ordinance 2015-2. If it goes into effect on June 1 as scheduled, Ordinance 2015-2 will limit noise to a maximum of 35 dB(A) and/or 50 dB(C) between the hours of 10 p.m. and 6 a.m. Heritage alleges that these restrictions would essentially make it impossible for the wind farm to continue operating at full capacity during these times.
The state high court overturned a lower court ruling Thursday that had chastised the Department of Environmental Protection’s commissioner for loosening noise requirements for the island’s wind turbines.
Huntingdonshire District Council confirmed yesterday (Tuesday) it will be measuring levels at the Cotton Farm Wind Farm, on a former airfield, after receiving a flood of complaints about noise from people living in surrounding villages.
More homes than previously reported are affected by sound outside of acceptable limits from the Independence wind turbine. A final report from consultants hired to conduct a sound study shows additional exceedances of state Department of Environmental Protection noise regulations and policy beyond those identified in the initial acoustical monitoring study report.
Senator Day applauded the bravery of landholders opposed to wind farms and said renewable energy operators needed to take their concerns more seriously. “Scientists and doctors are only just beginning to understand the connections between the infrasound emitted from turbines and the impact on the health of nearby residents.”
The Expert Panel’s assessment was extensive; they considered a wide range of evidence and developed a rigorous methodology for their work. The resulting report provides key information and insights on what is known and not known about wind turbine noise and its possible impacts on human health.
Under these low wind speeds, a turbine creates sort of a “woosh.” And it seems like the wooshes will never end. “When the wind is in the west, we don’t hear it,” he said, referring to the turbine east of his farmstead. When the wind is blowing out of the east or south, “It’s almost like when you’ve got cars going by.”
Sonia Trist moved from Britain to the spectacular rolling hills overlooking the Southern Ocean at Cape Bridgewater in Victoria’s southwest in 2007 knowing that wind turbines would soon surround her new home. What she was not expecting were health problems including sleeplessness, heart palpitations, high blood pressure and dizziness, which she says she began to suffer months after the turbines began operating.
Cooper told yesterday’s senate hearing how Pacific Hydro had effectively gagged him from publishing or presenting papers on the results of his work by claiming copyright. There was also evidence that by limiting the number of participants in the Cape Bridgewater survey to six, the company had built into the research brief a ready defence to attack what Cooper had found.
The wind farm company which commissioned a recent groundbreaking study investigating links between health complaints and low-frequency noise generated by wind turbines has told a Senate committee it was “never meant to be a scientific study”.
Finnish legislation determines a 40 decibel noise limit over an hourly average at night in proximity to any housing. But the government in 2012 issued new guidelines that lower that limit to 35dB. ...The new limit would mean that no wind parks could be built closer than two kilometres from any holiday cottages.
