Regarding Minoru Matsutani's April 12 article, "Offshore windmills weather crisis": Sonic waves from wind turbines do not make people feel ill. Studies in Canada, the United States and Australia have shown that the sound is safe.
A study from the chief health officer for Ontario, released in May 2010, states that "the scientific evidence available to date does not demonstrate a direct causal link between wind turbine noise and adverse health effects. ... The sound level from wind turbines at common residential setbacks is not sufficient to cause hearing impairment or other direct adverse human effects.
"Low-frequency sound and infrasound from current generation upwind model turbines are well below the pressure sound levels at which known health effects occur. Further, there is no scientific evidence to date that vibration from low-frequency wind turbine noise causes adverse health effects."
