Altered cortical and subcortical connectivity due to infrasound administered near the hearing threshold – Evidence from fMRI

Journal.pone.0174420-infrasound_thumb The findings of this study  demonstrate that infrasound near the hearing threshold may induce changes of neural activity across several brain regions, some of which are known to be involved in auditory processing, while others are regarded as keyplayers in emotional and autonomic control. In other words, sound that is not audible can still trigger a response in the human brain.

Rand: Critique of Noise Impact Report for NextEra's Golden West Wind Energy Center

Rand_review_epsilon-4177-goldenwest-170321_thumb NextEra's Golden West Wind Energy Center sited in El Paso County, Colorado was required under the County permit to conduct a noise impact study after the project was placed in service in October 2015. Acoustician Robert Rand was asked by residents living near the turbines to review the noise impact study as prepared by NextEra consultant, Epsilon Associates. Mr. Rand's report, included here, identified several material errors with Epsilon's report and also found that the project appears to be operating outside the noise limits permitted by the County and the State. The Golden West Wind Energy Center consists 145 1.72-megawatt GE turbines for a total installed capacity of 249.4-megawatts Mr. Rand's executive summary is provided below.

Comments by the Academic Editors Regarding: “Evaluation of Quality of Life of Those Living near a Wind Farm“:

Ijerph-14-00141-v2-mroczek_thumb These papers document an important debate between wind-friendly academics who argue that those living near wind turbines benefit from the experience and those who insist such conclusions are backed by inappropriate study methodologies and broad assertions that cloud actual findings. In this circumstance, Dr Daniel Shepherd a PhD in psychoacoustics and head of research at AUT University in Auckland, New Zealand, challenges the methods and conclusions of Mroczek et al.’s “Evaluation of Quality of Life of Those Living near a Wind Farm“ published in the International Journal of Environmental Research and Public Health, 2015, 12, 6066–6083. The academic editors of the Journal, after granting Mroczek the opportunity to respond, agree with Shepherd's main criticisms. In total, there are four papers documenting this debate; three are attached to this page. These include Shepherd's critique, Mroczek's response and the position of the Journal's academic editors. Portions of the response by the Journal's editors are also provided below.

Wind Turbine Noise and Human Health: A Four-Decade History of Evidence that Wind Turbines Pose Risks

This important peer-reviewed paper examines 15 years of the authors' combined experience with wind turbine noise issues. The authors respond to the various responses by the wind industry regarding turbine noise and explain why audiologists, particularly those interested in community noise, should embrace the notion that all forms of noise, if sufficiently intense and prolonged, can be detrimental to public health. They also encourage audiologists to be sensitive to the non-auditory aspects of acoustic energy, including the dynamically modulated infrasound and low-frequency sound emitted by modern wind turbines. The background information about the paper is provided below. The link(s) to download the paper are included on this page.

Indoor simulation of amplitude modulated wind turbine noise

Indoor_simulation_of_am_wind_turbine_noise-10-1002-we-2019_thumb This important paper examines how wind turbine noise, particularly noise from larger turbines, falls in the lower frequency range, below 1000 and 500 Hz. This type of noise penetrates homes and creates sleep disturbance. The researchers found that, in general, the indoor noise levels of homes near turbines are higher which helps explains noise annoyance complaints. The abstract of the paper is provided below.

Minnesota Public Utilities Commission examines turbine noise complaint

Bent_tree_commerce_to_mpuc_4-11-2016_thumb Phase I of the Bent Tree Wind Project began operation in January 2012. The project consists of 122 Vestas V82/1650 (1.65 MW, diameter 82 m) turbines for a total installed capacity of 201.3 megawatts. Noise complaints were filed by at least two landowners since September 2015. Staff for the Energy Environmental Review and Analysis (EERA)  unit of the MN Department of Commerce examined the complaints and believe the complaints are both Unresolved and Substantial. In this letter with supporting documentation, EERA staff recommended the MN Public Utilities Commission initiate the process for addressing the complaint. The letter to the PUC is provided below. The full letter with documentation can be accessed by clicking the links on this page.

Professional Caution to Brown County Health Director Chua Xiong

Rand_to_evans_and_tibbetts_23feb16_631pm_thumb In this powerful letter to the Brown County, Wisconsin Health Board, acoustician Robert Rand explains his obligations under INCE Rules of Practice to notify the appropriate authorities if he believes his professional judgment pertaining to human health impacts has been overruled. In this instance, Mr. Rand is responding to a decision by the county's health officer, Chua Xiong, to rule against the work of the Health Board and find that there is insufficient evidence to show a relationship between wind turbines and health concerns. Mr, Rand was one of four acousticians who studied the noise issues at the Shirley Wind facility. The final report showed that all of those involved with the study, including acousticians who work largely for the wind industry, agreed they had found sufficient evidence to classify low-frequency noise and infrasound emanating from the turbines as a serious issue.

Letter: Listen to experts on turbine noise

Stephanieliumoeccletternov20noiseregreview_thumb Wind Concerns Ontario submitted these comments to the Green Energy Approvals section of the Ministry of the Environment and Climate Change (MOECC), following testimony from acoustics experts at the appeal of the White Pines wind power project. In the letter (provided below and attached to this page), WCO requests that the MOECC review the testimony of the witnesses, specifically that Ontario’s noise regulations are inadequate to protect health, and to apply the information to the current review of noise regulations for wind turbines underway in the province. The White Pines Wind Project, if built, will consist of 29 wind turbines with a nameplate capacity of 59.45 megawatts (MW) situated in within the ward of South Marysburgh and a small portion of Athol, Prince Edward County, Ontario. For more information pertaining to the White Pines wind application appeal before the Ontario Environmental Review Tribunal, see this website - https://appec.wordpress.com/

Comments by Queensland Government Noise Expert - Dr Antoine David

R_15-127_-_file_a_thumb These documents, secured under the Australian Right to Information (RTI) Act, reveal that warnings from the Queensland Government's own noise expert were not provided to the public or passed on to the Planning Department or the Minister for Planning to inform the wind turbine siting process. Dr Antoine David, the noise expert in the Department of Environment and Heritage Protection provided his superiors with a list of nine points of concern regarding the draft Wind Farm Code. The list of his concerns is provided below and can also be found on page 7 of the attached document. A RTI request revealed that, despite making his concerns known within his department, Dr. David's findings were not forwarded to the Department of Infrastructure, Local Government and Planning, the department responsible for developing the current draft (version 2) of the Wind Farm Code.

Infrasound: Low frequency noise and industrial wind turbines

Infasound__and_wind_turbines_final_version_4_august_2015_thumb With the proliferation of recent research and the rediscovery of earlier, until now largely ignored studies, infrasound and low frequency noise (LFN) can no longer be dismissed as irrelevant. This report shows why LFN must be given full consideration as a contributing cause of the distress of some of those people living near wind turbine installations. It also demonstrates why the Ontario and Canadian governments must pay attention to this research. The table of contents for the report is provided below. The full report can be accessed by clciking the links on this page.
