Windmill noise levels

I am responding to the letter “Tilting at Windmills” (BDN, Nov. 18). I love these people who say they stood at the bottom of a windmill and couldn’t hear it. Probably you couldn’t. The noise levels that are of most concern to those of us who have made it a passion to study wind turbines are called infrasound and ultrasound. This is noise that falls outside the normal range of human hearing. It causes great stress not only in human beings but also in all types of animals. This type of noise can be sensed from as far away as three miles, and you don’t hear it; your body “feels” it. It reportedly causes stress, insomnia, discontent, disorientation, serious problems in people with autism and many more problems.

If Ron Porter would take the time to go online to www.wind-watch.org or just go online and type in words such as “Calgary wind turbines,” or just “wind turbines” he would rapidly see for himself how dangerous these are to the general welfare of all living things.

I have spent hours and hours a day looking at this issue. Much of the research is done by professionals including medical doctors. I have spent a lot of time talking to people who live near wind turbines, and their stories are truly sad. I wish people would educate themselves before they comment.
