As for the tranquillity that the EMLRLG talk about, wind turbines do not make much noise and can not often be heard at all at distances greater than a kilometre or two.

Turbine towers could not be taller than 500 feet from base to blade tip, and they could not emit noise greater than 45 decibels at the property line.

The level of background noise at distances of a kilometre or more from wind turbines makes measuring the effect of sound from wind turbines on people at such distances complicated.

The consequences of exposure to impulsive infrasound and low frequency noise generated by wind turbines were also clearly well known to the global wind industry, because of the dramatic change in design which resulted, and because the results were presented at the AWEA sponsored conference.

On January 9, 2009, the New York Supreme Court annulled a town law regulating large wind turbines because the town board did not take a «hard look» at relevant areas of environmental concern, and it disregarded study committee recommendations for setbacks and noise standards to protect the health and well - being of residents.

In several records, staff noted that wind turbine noise exceeded regulations: ««Staff have attended at the complainants homes on multiple occasions... noise measurements were obtained... subjective observations were made by Provincial Officers... the conclusion of the POs were that the noise emissions from the wind turbines were causing an adverse effect contrary to S. 14 (1) of the EPA at the complainants locations...»

In Australia, where the controversy is reaching new heights, a wind industry executive has been singling out Dr Sarah Laurie in a bid to make the public forget the many other health professionals who alert the public to the dangerous effects of wind turbines: «[T] he largest public relations issue for the industry at the moment is the theory of an ex-doctor that infrasound or low frequency noise from wind turbines is likely to make anyone within 10 km of a wind turbine sick» (2).

«Whilst the aerodynamic noise from a rotating turbine blade produces energy in the infrasound range, measurements of infrasound noise emissions from modern upwind turbines indicates that at distances of 200 metres, infrasound is in the order of 25 dB below the recognised perception threshold of 85 dB (G) and other similar recognised perception thresholds (Hayes Mckenzie Partnership Ltd, 2006).
