Dr. Sarah Laurie statement of evidence given at a recent court case  (February 2013)
IN THE VICTORIAN CIVIL AND ADMINISTRATIVE APPEALS TRIBUNAL


45. There is, however, human and animal research in the fields of infrasound and low frequency noise, which provide direct empirical experimental evidence that both infrasound and low frequency noise can cause a range of physiological stress effects and symptoms, many of which are also being reported by wind turbine residents. Sound in those frequencies is now being measured inside the homes of sick people, and preliminary data is showing direct correlation between certain frequencies and specific symptoms.

46. One useful literature review detailing research into infrasound was conducted in 2001 by the United States National Institute of Environmental Health Sciences, with the title “ Infrasound – Brief Review of toxicological Literature”. It is attached as annexure 5. Some of the animal studies listed show evidence of a physiological stress response, although generally the doses of infrasound are higher than those extremely limited data sets of full spectrum acoustic measurements inside and outside homes at existing wind developments, but the exposure durations are very short, in comparison to living 24/7 for 25 years beside a wind turbine development. The report makes it clear that there are significant knowledge gaps with respect to chronic exposure to infrasound at lower “doses” particularly, stating: “Examples of critical data gaps include a lack of high quality long-term experimental studies of infrasound, and inadequate characterization of environmental infrasound and accompanying higher frequency sound levels in community settings”
