Here’s a new one: Wind Turbine Syndrome. Seems that people living near wind turbines are reporting symptoms of “sleep disturbance, headache, dizziness, vertigo, nausea and panic episodes “associated with sensations of internal pulsation or quivering which arise while awake or asleep,” according to Dr. Nina Pierpont. She has written a book about it called “Wind Turbine Syndrome” and subtitled “A Natural Experiment”. I’m not sure what makes an experiment natural or not. You can see its claims at windturbinesyndrome.com.
This just sounds fishy from the start, one of the usual new-technology-will-eat-your-children kinds of things, like microwave ovens, cell phones, and numerous others. On the other hand, it does seem in some ways plausible to me. The constant low hum is said to mess with the inner ear, and the inner ear is related to balance and disorders there can induce vertigo. The latter two claims are fairly well established in medicine, the former, not so much, so far as I know. I can’t say for sure. I know far more about sound than I do about the medical aspects of hearing. The visual aspects of huge wind turbines can cause some effects as well, if the shadows of the blades are constantly in your field of vision. Imagine the scene in the horror movie in the dark barn where the guy with the machete is about to jump from behind something. Isn’t it always lit solely by sunlight passing through the blades of a slow-moving fan? It’s used because it is very disorienting.
My understanding of the inner ear is that it is filled with fluid sort of like a carpenter’s level. When we change the angle of our head, the bubble moves to a different spot, and we perceive this as movement. When we spin, we get this fluid all in a tizzy, and this is the sensation of dizziness. Our visual senses also play into this, and tricking them can produce a similar experience, a fact exploited by those amusement park rides that have a big screen but don’t really go anywhere.
Sound is the action of air pressure changes as perceived by the ear. It comes in waves, what we sound engineers would consider pushes and pulls on a speaker. Think of the shape of a speaker. It is basically a bowl that collects the air in front of it, and pushes it outwards. It must then pull back before repeating the push. In the push air is actually more dense, and in the pull, less so. Humans hear roughly down to 20 hertz, or twenty of these cycles per second, though the ear drum is certainly pushed by lower. Volume is essentially a measure of the air pressure of the wave front. You’ve seen the Mythbusters where the candle gets blown out by the speaker, and they had to get a very low note to pull it off. The reason for this is that the front of the air movement blows the candle, and the less dense air behind the push isn’t enough to keep the candle lit.
Now imagine if you had a low rumble, ten hz or less, and you got a phasing issue, where when one ear is getting a push, and the other a pull. Disorienting. But also notice that the sound of mysterious hums often is reported as having similar effects on people as those claimed in this book. Many of these hums have been unprovable, but some have been tracked down satisfactorily to a particular source, some giant industrial fans in one town. When these were dealt with, the sounds went away and everybody lived happily ever after.
One other characteristic of low frequency noise is that it travels very far. Whales use low frequency to map out vast areas of ocean, as does Navy sonars.
So let’s right now call this plausible, but needing further study. The hypothesis is sound, if you pardon the pun. I also think these studies will eventually happen if the movement that follows this book is vocal enough.
The problem with this book is that it skipped this step and went directly to publication. I think it is obvious that with the recent focus on green power, the technologies are in the news. If you want to make a quick buck, sensationalizing the next big thing is a great way to go.
I’m not one to attack a doctor’s cred or anything like that. I’ll assume that Dr. Pierpont has more meaningful degrees and schooling in the subject than I, and I will leave the background check to other authorities. She has four peer reviews on the site by people that I will regard in the same way, credible until proven otherwise. The problem is on the website, the peer reviews are more like blurbs on a bestseller. They don’t convince me of the veracity of the book’s claims, only in its intent to make money.
In the end the real problem with the book, which I don’t have in my hands, and I admit am criticizing from afar, is that Dr. Pierpont has rushed to publish this in a book to peddle to the masses rather than seek funding and undertake the study herself. I’m sure it would be available. I’d start asking the manufacturers for study funds, after all, they would be liable if their product caused illness. The government could probably put some money to this as well, after all, wind power is certainly part of our future. Once this study is done, publish it in a peer-reviewed journal, not in your own book where you get to pick your own peers. If you survive this, then you publish the book and go on Oprah and all of that.
The rush to publish this book is problematic in that it isn’t just premature, it will give never ending fuel to the fire of conspiracy theorists and whackadoos that insist that the wind turbine is ruining their lives, electromagnetic broadcasts are giving them brain cancer, and microwaves poison their food. This sort of alarmist writing is just bad science that will inevitably hinder the growth of clean power for no good reason.
