Documents filed under Noise from Australia / New Zealand
In this letter to the Association of Australian Acoustical Consultants (AAAC), Dr. Alec Salt responds to the AAAC's position on wind turbine emissions and infrasound. In particular, Dr. Salt admonishes the AAAC for insisting that low-frequency sound emitted by turbines is no higher than infrasound levels measured at locations where other people live, work and sleep.
This open letter written by Mauri Johansson, MD, MHH, a specialist in Community and Occupational Medicine, reveals important information about the impacts of wind energy development on communities in Denmark and how these impacts are being exported to other countries.
Professor Colin Hansen of the University of Adelaide in South Australia authored this important critique where he explains that low-frequency noise produced by industrial scale wind turbines, in fact, does fall within the threashold of human hearing and can disturb sleep and lead to other possible adverse health effects.
This letter was submitted to the Victoria Department of Health in response to the Department's report entitled "Wind Farms, Sound and Health: Technical Information". Dr. Alex Salt critiques the report's assertions regarding inaudible noise and human health.
This letter by acoustician, Ray Tumney, addresses a consistent resistance by the Australian Acoustical Society to address the problem of wind turbine noise emissions. A portion of his letter is provided below. The entire letter can be accessed by clicking on the link at the bottom of this page. Mr. Tumney's letter supports comments by acoustician Stephen Cooper's document on this issue (http://www.windaction.org/documents/35844 ).
This document by acoustician Graeme Harding offers a clear explanation surrounding the debate of wind turbine noise and the failure of acoustical experts to reach agreement on the problem.
Dr. Steven Cooper, an Australian acoustician with considerable experience measuring wind turbine sound emissions, prepared this important and detailed critique of a study sponsored by the South Australia EPA on low-frequency noise. The SA EPA report insisted that infrasound emitted by wind turbines was not different from infrasound from other sources in the environment. Dr. Cooper exposes the fatal flaws in the EPA's methodology for surveying the sound. Excerpts of his critique are provided below. The full report can be accessed by clicking the link at the bottom of this page.
The following speech was given on the floor of the Australian Parliament, House of Representatives, by the Member for Hume, Alby Schultz. Mr. Schultz addresses the failure of the Waubra wind farm and others to operate within the limits of their permits, the high cost and inefficient operation of wind turbines and, what he deems fraudulent issue of RECs to shell companies overseas.
David and Alida Mortimer host two Vestas 1.75 megawatt wind turbines in the Lake Bonney windfarm. Since the wind project went into service, he and his wife moved into a new farmhouse that they built away from the turbines. The new house is approximately 2.5 km from from a cluster of four turbines situated on his neighbor's property. The problem of noise has been significant. Mr. Mortimer filed this testimony before the Victorian Civil and Administrative Appeals Tribunal in reference to the Cherry Tree Wind Farm proposal. In his testimony, Mr. Mortimer details the disruptions and health complaints he and his wife are experiencing as a result of the turbines.
These important comments prepared by Dr. Michael Nissenbaum respond to questions raised by the Australian Senate Environment & Communications committee during its inquiry into wind turbine noise. In particular, Dr. Nissenbaum explains how the 'nocebo' effect is not a factor and that health complaints reported by those living near large turbines are real and require attention.
Measurements were undertaken both indoors and outdoors at a typical rural residence approximately 2km from the nearest wind turbines at Waterloo wind farm to determine the appropriate turbine noise limits for rural areas. The abstract and conclusions of the paper are provided below. The full paper can be accessed by clicking the links on this page.
This important paper by acoustics expert, Steven Cooper, challenges the current standards for siting wind turbines in Australia.
This peer-reviewed report written by the Acoustics Group in Australia evaluates the noise impact assessment for the Collector wind farm proposed to be built in New South Wales. The project will have up to 68 turbines but the turbine make and model is still undetermined. Three turbine makes and models were considered: Suzlon S88-2.1MW, V3; REpower 3.4M 104; Siemens SWT-2.3-101. The introduction and conclusion of the report is shown below. The full report, with appendices, can be accessed by clicking on the links at the bottom of this page.
Australian acoustician Steven Cooper examines the responsibility of Members of the Australian Acoustical Society to a community where people are forced to leave their homes because of wind farm "noise". His technical note can be accessed by clicking at the links at the bottom of this page.
The government of South Australia issued two series of "Wind farms environmental noise guidelines" in 2003 and 2009, aiming to balance the advantage of wind energy development in South Australia with the protection of amenity of the surrounding commmity from adverse noise impacts. This briefing paper sums up a study undertaken during 2011 evaluating the efficiency and adequacy of these guidelines.
This important study exposes the significant flaws found in the preconstruction noise modelling produced for the Flyers Creek Wind Farm. The authors validated their findings by conducting noise surveys at an operating wind energy facility within the same region of Australia.
Dr. Daniel Shepherd was invited by the Ohariu Preservation Society in New Zealand to provide an evaluation of the impact of turbine noise on health and well-being. The report specifically references the proposed Mill Creek wind energy facility proposed to be built on rural land northwest of Wellington, New Zealand in the Makara and Ohariu valleys. His full report can be accessed by clicking on the link at the bottom of this page. The conclusions of his report are shown below.
This book was recently released in New Zealand. The below introduction explains the premise behind the text. Visit the link below to view excerpts or for contact information of the authors.
Mr and Mrs Noel Dean requested a Report providing an assessment of the potential for adverse effects due to activity from the Waubra wind farm while living in their residences and while working on their farms. Dr. Robert Thorne undertook the study. His full report can be accessed via the link at the bottom of this page. Below is a summary of Dr. Thorne's findings and conclusions.
The expressions “Environmental Sustainability” and “Resource Management” may seem to be synonymous. In the original concept this could have been the intent, but now that we have in operation a number of alternative energy sources to offset the use of fossil fuels, unforeseen emissions may be affecting local communities in the vicinity with the possibility of public health being compromised. Wind farms are an alternative energy source and the effects of noise emissions on the health of people living within several kilometres of the wind farms is becoming a concern. The noise level from a wind farm may be quite low, but its characteristics compared to that of the normal background sound make it stand out as something quite different, and its ability to excite room resonances makes it an irritant causing severe loss of sleep and extreme annoyance. Often the sounds are heard more clearly indoors than outside. New Zealand Standard 6808 on the noise from wind turbines has been reviewed and a new draft standard produced for public comment. The draft differs little from the existing standard and closely follows that used in Britain and parts of Europe, even though there are clear indications that the criteria to be met do not fully conform with World Health Organization recommendations, and the methodology used is likely mathematically, scientifically and ethically wrong. The draft and similar standards across the world are clearly biased towards wind farm development for as little cost as possible, and it appears public health concerns are not being given enough attention.
