Quotes from article:
"There is no conclusive evidence so far that wind turbines are responsible for health problems ranging from balance problems to diabetes, an independent panel of health experts reports.
There is no evidence for a set of health effects characterized as “wind turbine syndrome.”
The Massachusetts Department of Environmental Protection (MassDEP) in collaboration with the Massachusetts Department of Public Health (MDPH) convened a panel of independent experts to identify any documented or potential health impacts of risks that may be associated with exposure to wind turbines, and, specifically, to facilitate discussion of wind turbines and public health based on scientific findings. http://www.mass.gov/dep/energy/wind/impactstudy.htm

2. The sound power level of a typical modern utility scale wind turbine is on the order of
103 dB(A), but can be somewhat higher or lower depending on the details of the design
and the rated power of the turbine. The perceived sound decreases rapidly with the
distance from the wind turbines. Typically, at distances larger than 400 m, sound
pressure levels for modern wind turbines are less than 40 dB(A), which is below the level
associated with annoyance in the epidemiological studies reviewed

Why is this even an issue? I commonly see wind turbines installed in areas remote from Human living areas. Installing them in median strips and in fields should provide suitable safety margins.
