Wind Farms: Environmental Noise Guidelines

Wind_farms_environmental_noise_guidelines_australia_thumb "This document aims to help developers, planning and enforcement authorities, other government agencies and the broader community assess environmental noise impacts from wind farms. The core objective of these guidelines is to balance the advantage of developing wind energy projects in this State with protecting the amenity of the surrounding community from adverse noise impacts. Wind farms need specific guidelines because wind turbines have unique noise generating characteristics and the environments surrounding wind farm sites usually have low ambient noise."

Kelly Alexander's Home, Machinaw City: Photo and Map re. Noise

Snoisyhouse_thumb Kelly Alexander believed that windpower would be a good energy source. He was told the machines were not noisy. No one told him about the blade flicker that shines even through closed blinds or the low frequency noise that penetrates his home with doors and windows tightly closed and storm windows installed. Recently, the turbine owner visited Kelly and asked what he could do to help the situation. He said, “Stop lying about these turbines. Tell people the truth.”

Correspondence: UK Specialist on Noise

Uk_noise_specialist_thumb Thank you for your enquiry about wind farm noise. I should probably explain my background and interest in wind farms. I have been a noise and acoustic consultant for more than 30 years and most of my current work is dealing with the assessment of environmental noise as it affects residential properties. I work equally for those potentially creating noise and those affected by it. I have been a supporter of wind energy and other forms of renewable energy for some 35 years. I have carried out noise assessments for both “sides” in planning applications for wind farms and adopt the same method of assessment whoever employs me.

A case study of low frequency noise assessed using DIN 45680 criteria

J165244-casestudylowfrequencynoise_thumb This paper describes a case study in which low frequency noise (LFN) was suspected of causing disturbance in a semi-rural location close to an industrial estate. Previous attempts using conventional acoustic measurement techniques to resolve the case, or even prove the existence of a real acoustic problem, had proved unsuccessful. The study does not involve wind turbine noise directly, but the work done and resulting findings provide insight into identifying the problem of LFN and predicting annoyance.

Comments for the Lincoln Township Wind Turbine Survey

Commentslincolntownship_thumb Lincoln Township in Wisconsin sent a survey to its residents to help assess the impacts of 22 turbines installed by Wisconsin Public Service Corporation (WPSC) and Madison Gas and Electric (MG&E), which went online in June 1999. A summary of the survey comments received is provided in the attached document. After the wind turbines went online, the Lincoln Township Board of Supervisors approved a moratorium on new turbine construction.

David M. Lipscomb PhD testimony on noise and human health

Lipscomb-june2000_thumb Dr. David M. Lipscomb PhD provided this testimony before the State of Washington Energy Facility Site Evaluation Council involving the risks of noise emissions from then proposed Sumas Generating Plant on human health. An excerpt of the testimony is provided below. The full testimony can be downloaded by clicking on the link at the bottom of this page.

Guidelines For Community Noise

Comnoise-1_1__thumb This WHO document on the Guidelines for Community Noise is the outcome of the WHO- expert task force meeting held in London, United Kingdom, in April 1999. It bases on the document entitled “Community Noise” that was prepared for the World Health Organization and published in 1995 by the Stockholm University and Karolinska Institute.

Community Noise

World_health_organization_study_-community_noise_thumb The document critically reviews the adverse effects of community noise, including interference with communication, noise-induced hearing loss, annoyance responses, and effects on sleep, the cardiovascular and psychophysiological systems, performance, productivity, and social behavior. Noise measures or indices based only on energy summation are not enough for the characterization of most noise environments. This is particularly true when concerned with health assessment and predictions. It is equally important to measure and display the maximum values of the noise fluctuations, preferably combined with a measure of the number of noise events, and to assess whether the noise includes a large proportion of low frequency components.

A Proposed Metric for Assessing the Potential of Community Annoyance from Wind Turbine Low-Frequency Noise Emissions

Wind_turbine_low-frequency_noise_emissions_thumb This paper, presented at the Windpower ’87 Conference & Exposition in San Francisco by N.D. Kelley, a physicist at the Solar Energy Research Institute in Golden, Colorado validates the fact that turbines (both upwind and downwind) produce low-frequency sound emissions that can negatively impact humans within their homes. Although modern wind turbines are different from those studied in 1987, the research is significant in that it demonstrates the need to test for low-frequency sound emissions and to do so inside buildings.

Acoustic Noise Associated with the MOD-1 Wind Turbine: Its Source, Impact, and Control

Acousticnoisemod-1windturbine_thumb This report summarizes extensive research by staff of the Solar Energy Research Institute and its subcontractors conducted to establish the or1g1n and possible amelioration of acoustic disturbances associated with the operation of the DOE/NASA MOD-1 wind turbine installed near Boone, North Carolina. Results have shown that the most probable source of this acoustic annoyance was the transient, 'unsteady aerodynamic lift imparted to the turbine blades as they passed through the lee wakes of the large, cylindrical tower supports. Nearby residents were annoyed by the low-frequency, acoustic impulses propagated into the structures in which the complainants lived. The situation was aggravated further by a complex sound propagation process controlled by terrain and atmospheric focusing. Several techniques for reducing the abrupt, unsteady blade load transients were researched and are discussed.

Professor Terry Matilsky on Noise Impacts

Terry_matilsky__thumb This document has been prepared by Terry Matilsky, Professor of Physics at Rutgers University. For almost 40 years, he has been funded by NASA and other federal agencies to do data analysis from various scientific satellites; to examine what information tells us about a phenomena, and draw rational and solid, scientific conclusions from them.
