NOISE Wind
Turbine Noise What Audiologists should know by Jerry Punch, http://www.wind-watch.org/documents/wp-content/uploads/AudiologyToday-WindTurbineNoise.pdf Excerpt:
People living within a mile of one or
more wind turbines, and especially those living within a half mile, have
frequent sleep disturbance leading to sleep deprivation, and sleep
disturbances are common in people who live up to about 1.25 miles away. Important
Factors when planning a Wind Farm http://www.retexo.de/english/wind/seite5a.htm Excerpt:
Buildings, particularly housing, should not be nearer than 2 km to
the wind farm. GE Reports How Loud is a wind turbine? http://www.gereports.com/how-loud-is-a-wind-turbine/ For the stillest, most rural areas, Longtin says the background noise is 30 decibels. At that level, a turbine located about a mile away wouldn’t be heard. Vestas Policy on Noise from Wind Turbines Excerpt: Vestas also recommends that governments supplement relative noise limits with a low absolute maximum limit in areas of very low background noise (e.g. quiet countryside), which ensures minimal noise disturbance for turbine neighbours also in these places. National
Institutes of Health http://www.nidcd.nih.gov/news/releases/10/07_28_10.htm Excerpt:
Regardless, it
might not be enough to place wind turbines further away from human
populations to keep them from being bothersome, since infrasound has the
ability to cover long distances with little dissipation. Wind
Energy Resource Zone Board Comments: NASA Wind-Turbine
Noise Research http://efile.mpsc.state.mi.us/efile/docs/15899/0086.pdf Excerpt: These results have recently been re-confirmed by the work of den Berg (2004, [4] ) who has shown that wind gradients can increase sound levels at night by up to 15dB, and Pedersen (2004, [5] ), who has reported that wind-turbine noise is very much more annoying and intrusive than the criteria set by conventional dBA (e.g. EPA) considerations. He showed that annoyance rises rapidly for wind-turbine noise levels above 35dBA-38dBA. In this respect, problems such as those from the wind-farm recently established at Ubly, are not unexpected. Reports from families living close to Ubly who have had their lives disrupted by wind-turbines are entirely consistent with this prior NASA knowledge and research. I hope you will be able to take these comments into consideration. STATE

Hearing held before the Wind Energy Resource Zone Board, at the http://www.michigan.gov/documents/mpsc/windenergy-badaxe_292171_7.pdf Excerpt:
The
reality of our living nightmare is that we are not only woken from the
sound that you can hear, but there is a low-frequency noise in our home
that you can feel at night and sometimes all throughout the day.
