Infrasound Measurements of Falmouth Wind Turbines Wind #1 and Wind #2

Nce-report-of-february-27-2015_thumb This important study conducted at a home situated within 1300 feet of the Falmouth MA wind turbines identified infrasonic sound pressure levels inside the residence. These results are similar to results from other international researchers with references given in the report. The executive summary and conclusions sections of the report are provided below. The full report can be accessed by clicking the link on this page.

Wind Turbines: A different breed of noise?

Ehp.122-a20-adifferentbreedofnoise_thumb Nate Seltenrich, a science and the environment writer, explores wind turbine noise. In this report, he writes that "anecdotal evidence strongly suggests a connection between turbines and a constellation of symptoms including nausea, vertigo, blurred vision, unsteady movement, and difficulty reading, remembering, and thinking." An excerpt of his report is provided below. The full article can be accessed by clicking the links on this page.

Court order granting injunction; Falmouth turbine operations limited due to noise

Falmouthzbapreliminaryinjunctiondecisionandorder_thumb Two weeks ago, in the injunction hearing in the Town of Falmouth vs. the Falmouth Zoning Board of Appeals case where the ZBA decided that the wind turbines were a nuisance to Neil Andersen, both parties presented a 7AM to 7PM agreement to the judge.  Falmouth Selectmen subsequently disregarded that agreement and continued to run the wind turbines 5AM to 9PM.  One selectboard member advocated running the turbines 24/7 in spite of the Court's request. Hearing this, Superior Court Justice Christopher Muse granted the injunction sought by nearby residents. The order is available by clicking the link on this page.

Noise Test Procedure for Industrial Wind Turbines

Alliance-iwt-noise-protocol-submission-massdep-july-2013_thumb This letter, submitted to the Massachusetts Department of Environmental Protection (MA DEP) details the appropriate methodology for surveying turbine noise post-construction. The procedure was developed under the guidance of acoustician, Richard James of E-coustics Solutions. The criteria for compliance is specific to the Massachusetts state law regarding noise and will differ from other jurisdictions. However, the procedure should be consistent for all noise surveys.

Fairhaven Wind letter: Turbine noise studies tainted

Lettertokenkimmellreoctober15samplingissue_thumb The wind developer for Fairhaven Wind, two industrial-scale towers built near residences, has admitted that the sound survey conducted on October 15, 2012 was tainted due to one of the turbines, while still spinning, was not producing power. The developer insists human error was the cause but claims the no intent to artificially reduce the sound levels. The State of Massachusetts has ordered the results be discarded and for further studies to be conducted.

Wind turbine acoustic investigation: Infrasound and low-frequency noise—A Case Study

Wind_turbine_acoustic_investigation_infr_thumb Abstract Wind turbines produce sound that is capable of disturbing local residents and is reported to cause annoyance, sleep disturbance, and other health-related impacts. An acoustical study was conducted to investigate the presence of infrasonic and low-frequency noise emissions from wind turbines located in Falmouth, Massachusetts, USA. During the study, the investigating acousticians experienced adverse health effects consistent with those reported by some Falmouth residents. The authors conclude that wind turbine acoustic energy was found to be greater than or uniquely distinguishable from the ambient background levels and capable of exceeding human detection thresholds. The authors emphasize the need for epidemiological and laboratory research by health professionals and acousticians concerned with public health and well-being to develop effective and precautionary setback distances for industrial wind turbines that protect residents from wind turbine sound. A portiion of the report is provided below. Click the links on this page to access the full paper.

Falmouth Wind #1 post-construction noise survey

Finalfalmouthreportwithappendix_thumb The Massachusetts Department of Environmental Protection announced that one of the two turbines sited in Falmouth exceeds noise levels permitted under State law. The letter from the MassDEP confirming the findings of a sound survey as well as the study report can be accessed by clicking on the links at the bottom of this page. An excerpt of the MassDEP letter is provided below.

Mass DEP on turbine sound survey methodology

Falmouth_letter_fm_massdep__30jun2011_thumb This letter, prepared by the Massachusetts Department of Environmental Protection, details guidelines to the Town of Falmouth on conducting background noise levels. The Mass DEP explains its preference for sound surveys to be attended by trained personnel who can ensure the readings recorded by the equipment are not contaminated by transient noise sources.

Vestas raises concerns about turbine noise (Letter)

Brucemobbotttopotamis2010-08-03_thumb After noise complaints started coming in following the erection of WIND 1, the first Falmouth turbine at the wastewater treatment facility, Vestas required confirmation that the Town of Falmouth "understands they are fully responsible for the site selection of the turbine and bear all responsibilities to address any mitigation needs of the neighbors." WIND 2 would not be released to the town for erection until the letter was signed. The letter explaining the situation is provided below and can be accessed by selecting the link(s) on this page.

Model Amendment to a Zoning Ordinance or By-law: Allowing Wind Facilities by Special Permit

Model-allow-wind-by-permit_thumb As interest in wind energy spreads throughout the Commonwealth, it becomes clear that there is a need within the cities and towns of Massachusetts for suitable zoning by-laws that accommodate wind projects. To help address this need, the Massachusetts Division of Energy Resources and Executive Office of Environmental Affairs developed this Model Amendment to a Zoning Ordinance or By-Law to assist cities and towns in establishing reasonable standards for wind power development. The by-law is developed as a model and not intended for adoption without review by municipal counsel:

Wind Turbine Noise Issues

Windturbinenoiseissues_thumb "Wind turbines generate noise from multiple mechanical and aerodynamic sources. As the technology has advanced, wind turbines have gotten much quieter, but noise from wind turbines is still a public concern. The problems associated with wind turbine noise have been one of the more studied environmental impact areas in wind energy engineering. Noise levels can be measured, but, similar to other environmental concerns, the public's perception of the noise impact of wind turbines is in part a subjective determination. Noise is defined as any unwanted sound. Concerns about noise depend on 1) the level of intensity, frequency, frequency distribution and patterns of the noise source; 2) background noise levels; 3) the terrain between the emitter and receptor; and 4) the nature of the noise receptor. The effects of noise on people can be classified into three general categories (National Wind Coordinating Committee, 1998): 1) Subjective effects including annoyance, nuisance, dissatisfaction 2) Interference with activities such as speech, sleep, and learning 3) Physiological effects such as anxiety, tinnitus, or hearing loss"........ prepared by the Renewable Energy Research Laboratory Center for Energy Efficiency and Renewable Energy Department of Mechanical and Industrial Engineering University of Massachusetts at Amherst
