The most common source of complaint from those unfortunates forced to live next to wind farms is the incessant low-frequency noise and infrasound generated by giant industrial wind turbines: turning a quiet night in into an occasion of acoustic torture (see our post here); and destroying many a good night’s sleep (see our post here).

But the low-frequency noise and massive air pressure fluctuations generated by giant fans have never been part of any noise standard or regulation for wind farms.

The noise standards – written by the wind industry – rely on the dB(A) weighting and, therefore, deliberately ignore the vast bulk of the sound energy produced by turbines – which pervades homes as infrasound and in frequencies that cause sleep deprivation and other adverse health effects (see our post here).

The idea of “testing” for the impacts from turbine noise and vibration without including infrasound and low-frequency noise is completely bonkers. Dr Mariana Alves-Pereira – who has been studying low-frequency noise impacts with her research group for 30 years, certainly thinks so (see our post here).

The standards not only ignore infrasound, but the South Australian EPA’s noise guidelines even ludicrously assert that infrasound was a feature of earlier turbine designs that is not present at “modern wind farms”. SA’s EPA – despite being incapable of following its own guidelines when it came to noise testing at Waterloo – managed to find infrasound present inside neighbouring homes at a very modern wind farm, that started operation in 2010 (see our posts here and here).

For a great little summary on wind turbine generated infrasound and its adverse affects on health, check out this video of Professor Alec Salt laying it out in clear and simple terms:

Given the work of Professor Salt (outlined in the video) and Steven Cooper’s findings at Cape Bridgewater (see our post here) the need to mandate the proper measurement of turbine low-frequency noise and infrasound as part of any reasonable noise standard is simply common sense.

The direct link between very low-frequency turbine noise, sleep disturbance and annoyance was well and truly established by Neil Kelley & Co over 25 years ago (see posts here and here and here). And the wind industry knew all about it (see our post here).

But, the wind industry has steadfastly refused to be regulated by science, common sense or, especially, by any form of human decency (see our post here). Danish fan maker, Vestas went so far as to lobby the NSW Planning Department to remove any reference to low-frequency noise from its draft noise guidelines – as well as the entire section on human health – with Vestas stooge, Ken McAlpine admitting that: “the existing and well validated industry standard models for acoustic propagation are NOT designed to deal with frequencies at the low end of the audible spectrum” (see this article and our post here).

The wind industry’s approach to noise regulation can wrapped us as follows:

• set the noise guidelines to cover up the obvious;
• pay a crack team of spin doctors and hack pseudo-scientists to run “interference” for you;
• be prepared to lie to Senate Inquiries
• whinge, dodge and avoid the imposition of reasonable noise standards – that apply to all other industrial noise sources; and
• when the victims start to become vocal and obvious PR problems – buy their homes using money from the REC tax on power consumers and then bulldoze them.

But – for the first time since the great wind power fraud kicked off – low-frequency noise and infrasound is about to appear on the wind farm noise regulation menu.

In Ontario, the lakeside county of Lambton has been speared with hundreds of giant fans. With turbines lobbed 550m from homes – wind farm neighbours have been slaughtered by turbine noise and vibration (see our post here). Locals there have been hammering their political betters for a better deal – and the Plympton-Wyoming Council has stopped to listen – introducing the kind of noise regulation that the wind industry has fought tooth and nail to avoid all over the globe. Here’s The Independent reporting on a win for common sense and human decency.

New bylaw will hold turbines companies to keep it down

Plympton-Wyoming’s proposed wind turbine noise bylaw is going where no regulation has gone before.

Council has given first and second reading to a bylaw which regulates the amount of noise coming from industrial wind projects. Council asked staff and the municipality’s lawyers to come up with the bylaw since much of the concern about the project has to do with the potential health effects of the noise coming from the turbine.

Clerk Brianna Coughlin says much of the regulation set out in the bylaw meets standards already set by the provincial government. “We can’t go beyond that,” she says.

But Plympton-Wyoming is going to hold the wind energy companies to a new standard. “The only difference (from the provincial standards) is the bylaw has mention of infra-sound which not regulated by the province right now,” says Couglin.

Infrasound is inaudible for most people but can be perceived by other senses and it is measurable according to some experts says Couglin.

Under the bylaw, if a resident complains about infra sound, the municipality would hire an engineer qualified to take the measurements before laying a charge.

Under the proposed bylaw, fines – if a company is found guilty – can range from $500 to $10,000 per offence and could exceed $100,000 if the offense continues. The municipality could also recoup the cost of the specialized testing under the bylaw.

Plympton-Wyoming Mayor Lonny Napper says that while Suncor Energy (which is developing the Cedar Point project in the municipality) has yet to comment on the inclusion of infrasound in the bylaw, he thinks it is necessary.

“We think it is our obligation to look after the health of the people,” he says. “You just can’t make rules and not cover everything.”

And he believes the proposed fines are appropriate. “It’s no worse than polluting,” he says.

Council will get another look at the bylaw Wednesday. Couglin says council could decide to hold a public meeting to get input or it could pass it without public comment that evening.

Meantime, the municipality also introduced a bylaw which would see Suncor provide a letter of credit for the value of the scrap metal for the turbines instead of providing a deposit.

The bylaw would also see Suncor pay building permit fees of nearly $300,000 for the 27 turbines it plans to erect near Camlachie.
