Speak up, buffy!

Sorry, I have no idea why that submitted.

While I was reading the Skeptic this afternoon I was made aware of a study done by SA EPA, comparing infrasound – the Big Bad Thing that supposedly makes people sick around wind turbines – at various places. So I looked up the report. Here is the link to the pdf:

http://www.epa.sa.gov.au/xstd_files/Noise/Report/infrasound.pdf

Cut and paste of the summary:

Summary of results
The range of measured Leq,10min infrasound levels at each of the measurement locations is
presented inFigure 1on the following page, with the lines corresponding to the minimum,25th
percentile, median, 75th percentile and maximum infrasound levels from left to right.

It is clear from the results that the infrasound levels measured at the two residential locations near wind farms (Location 8 near the Bluff Wind Farm and Location 9 near Clements Gap Wind Farm) are within the range of infrasound levels measured at comparable locations away from wind farms. Of particular note, the results at one of thehouses near a wind farm (Location 8) are the lowest infrasound levels measured at any of the 11 locations included in this study. This study concludes that the level of infrasound at houses near the wind turbines assessed is no greater than that experienced in other urban and rural environments, and that the contribution of wind turbines to the measured infrasound levels is insignificant in comparison with the background level of infrasound in the environment.

Sorry, took me a while to sort that out.

I think the OP sums it all up really.

Perhaps interestingly, the highest levels they measured were in their own offices…….

My dad has a hypothesis that the only people who complain about infrasound are the ones who aren’t getting any compensation from the wind farms.

He’ be right DA. (Scientific observation of the complainers around here)

Here is another interesting bit from the pdf:

“From an overall perspective, measured G-weighted infrasound levels at rural locationsboth near to and away from wind farms were no higher than infrasound levels measured at the urban ocations. Furthermore, both outdoor and indoor infrasound levels were typically below the perception threshold by a significant margin. The most apparent difference between the urban and rural locations was that human activity and traffic appeared to be the primary source of infrasound in urban locations, while localised wind conditions are the primary source of infrasound in rural locations.

An additional analysis of the frequency content of the measured infrasound levels was conducted for each location. At both of the wind farm sites, peaks in the frequency spectrum corresponding to the turbine blade pass frequency and related harmonics (0.8Hz, 1.6Hz and 2.5Hz) were identified that may be attributable to the wind turbines. However, these peaks were only detectable during periods of low wind speed and therefore ambient infrasound at the residence
s. The peaks in the spectrum were found to be no higher than infrasound levels measured at these frequencies at both rural and urban locations away from wind farms, and also significantly (at least 50dB) lower than the threshold of perception for these very low frequencies. “

Skrillex is still suffering from it.

Move along, nothing to see here.

I like this one because it agrees with mine.

There are probably certain small areas that have an annoying chopchop infrasound for short periods as the wind direction moves around. They are visibly seen in this pic that morrie posted some years ago:

I apologise for my brief foray into lucid discussion, and now return you to your previously expected idiocy.

>infrasound – the Big Bad Thing that supposedly makes people sick around wind turbines

It is simply an hypthesis, and measurements have failed to support the hypothesis. Big deal. It doesn’t mean people are not getting sick.

>My Dad has an hypothesis …..

Great. Lets accept that hypothesis without any proof, because it fits out idea that these people must all be whingers.

Case closed.

A slightly different topic related to windfarms came up on TV today. Apparently they get hit by lightning, not too surprising really, and that lightning can do a lot of harm, such as setting them on fire. So don’t stand under a wind turbine in a thunderstorm.

But what about the parrots?

They’re fine, thanks.
