Wind Turbine Sound
The sound of wind turbine blades passing through the air is often described as a “whoosh.” Measurements show that this sound is no louder than a kitchen refrigerator or air conditioning unit at a distance of 1,000 feet.
Low-frequency sound will be no different than waves on a beach and weaker than highway traffic, air conditioners, and other daily exposures.
Scientific evidence confirms that this sound is not dangerous and that any low-frequency waves produced are not harmful to those nearby.
“To date, no peer reviewed scientific journal articles demonstrate a causal link between people living in proximity to modern wind turbines, the noise (audible, low frequency noise, or infrasound) they emit and resulting physiological health effects.”
— Knopper and Ollson, “Health Effects and Wind Turbines: A Review of the Literature,” Environmental Health 10:78 (2011)
“... low level frequency noise or infrasound emitted by wind turbines is minimal and of no consequence ... Further, numerous reports have concluded that there is no evidence of health effects arising from infrasound or low frequency noise generated by wind turbines.”
— Australian Government, National Health and Medical Research Council, “Wind Turbines and Health,” July 2010
An independent organization of acoustical experts states that the infrasound generated by wind farms is lower than many other forms of infrasound already in the environment, including the sound produced by our own heartbeats.
Acoustic engineers are increasingly frustrated by community opposition to wind farm development as local opposition groups—often supported nationally by anonymous donors—snub scientific evidence in favor of myth and misinformation about turbine noise. Click here for the PDF.
