Infrasound and The Body

­How Stuff Works  by Julia Layton

The rapidly spinning blades of huge wind turbines have an effect on their surroundings, and it goes beyond aesthetics. The blade tips of a wind turbine can spin at speeds­ of up to 80 meters per second, or about 180 miles per hour. In high winds, this rapid spinning can produce sound a­nd vibration — in addition to disruptions in air pressure .

The extremely low air pressure surrounding a wind turbine could be the reason why bats die near them. A bat’s lungs are very delicate, and it seems the low pressure might cause them to expand to the point of bursting blood vessels. Scuba divers can certainly attest to the effects of pressure on the human body. And the corporeal effects of sound — essentially fluctuations in air pressure that vibrate the eardrum — are well-documented. For instance, infrasound — sounds at such low frequency that they can’t be picked up by the human ear but can carry through the atmosphere for thousands of kilometers — is believed to cause certain breathing and digestive problems.

Infrasound is the primary issue for those concerned about wind-turbine syndrome. They also say that audible sound and vibrations contribute to the health problems reported by some people who live close to wind farms. Symptoms of wind-turbine syndrome might include:

  • headaches
  • sleep problems
  • night terrors or learning disabilities in children
  • ringing in the ears (tinnitus)
  • mood problems (irritability, anxiety)
  • concentration and memory problems
  • issues with equilibrium, dizziness and nausea

These symptoms have been observed and documented by a limited number of scientists studying small groups of people, and the scientific community hasn’t conclude­d whether wind-turbine syndrome exists. There are also mixed opinions on whether wind turbines emit infrasound and if the amount is any more than that emitted by diesel engines or waves crashing on the beach . But we do know that at high speeds, wind turbines can produce an audible hum and vibration that can be carried through the air.

  1. By the time the overwhelming “proof” gets accepted that Wind Turbine Syndrome is real and the court challenges against the Wind Industry and Politicians becomes a reality the damage will already have occurred and we will be looking at one of the most “apocalyptic misadventures” ever carried out in the name of “saving the planet”!

    What a sad legacy for our generation to leave to our children and children’s children.

    All I can tell them is “I’m sorry I didn’t do more to stop this!”

  2. I don’t understand why we of the 47 communities in 27 counties don’t set a date to march in unison on Queen’s park! There is strength in numbers. We have enough information out of Europe and the economic disasters there due to the wind industry. With Japan setting a 4 year moratorium on health studies and more and more of the scientific community on board we have a very real opportunity to educate the masses that have been duped. We can no longer let the wind industry get away with their out right lies! Our outrage must be made known to our Premier! We must carry OUST McGuinty signs! Please everyone, let’s march soon. Every man woman and child who has had their home or community impacted by turbines with no concern for our health or devaluation of our homes! We must stand up and be counted. We need ACTION! letters to MPP’s and such don’t work! Set a date people and I will be there! My farm in Clearview reoresents all that is good about Canada and I will not stand behind political correctness and lose it!
