Health Canada, in collaboration with Statistics and other external experts, conducted the Community Noise Study to better understand impacts of wind turbine noise (WTN) on health well-being. A cross-sectional epidemiological study was carried out between May September 2013 southwestern Ontario Prince Edward Island 1238 randomly selected participants (606 males, 632 females) aged 18-79 years, living 0.25 11.22 km from operational turbines. Calculated outdoor WTN levels at dwelling reached 46...
The possibility that wind turbine noise (WTN) affects human health remains controversial. current analysis presents results related to WTN annoyance reported by randomly selected participants (606 males, 632 females), aged 18–79, living between 0.25 and 11.22 km from turbines. levels reached 46 dB, for each 5 dB increase in levels, the odds of reporting be either very or extremely (i.e., highly) annoyed increased 2.60 [95% confidence interval: (1.92, 3.58), p < 0.0001]. Multiple...
To investigate the association between self-reported and objective measures of sleep wind turbine noise (WTN) exposure.
Living within the vicinity of wind turbines may have adverse impacts on health measures associated with quality life (QOL). There are few studies in this area and inconsistent findings preclude definitive conclusions regarding impact that exposure to turbine noise (WTN) QOL. In current study (officially titled Community Noise Health Study or CNHS), World Organization QOL-BREF (WHOQOL-BREF) questionnaire provided an evaluation QOL relation WTN levels among randomly selected participants aged...
Anthropogenic activity has irreparably altered the ecological fabric of Earth. The emergence novelty from diverse drivers change is an increasingly challenging dimension ecosystem restoration. At same time, restorationist's tool kit continues to grow, including a variety powerful and prevalent technologies. Thus, restoration finds itself at center intersecting challenges. How should we respond common environmental system states with little or no historical precedent, whilst considering...
The current study was the first to assess stress reactions associated with wind turbine noise (WTN) exposure using self-reported and objective measures. Randomly selected participants, aged 18–79 yr (606 males; 632 females), living between 0.25 11.22 km from turbines, were exposed outdoor calculated WTN levels up 46 dBA (response rate 78.9%). Multiple regression modeling left great majority (77%–89%) of variance in perceived scale (PSS) scores, hair cortisol concentrations, resting blood...
This paper provides calculations of outdoor sound pressure levels (SPLs) at dwellings for 10 wind turbine models, to support Health Canada's Community Noise and Study. Manufacturer supplied measured power were used calculate SPL 1238 using ISO [(1996). 9613-2−Acoustics] a Swedish noise propagation method. Both methods yielded statistically equivalent results. The A- C-weighted results highly correlated over the (Pearson's linear correlation coefficient r > 0.8). Calculated SPLs...
This paper provides experimental validation of the sound power level data obtained from manufacturers for ten wind turbine models examined in Health Canada's Community Noise and Study (CNHS). Within measurement uncertainty, levels measured using IEC 61400-11 [(2002). (International Electrotechnical Commission, Geneva)] were consistent with provided by manufacturers. Based on measurements, also extended to 16 Hz calculation C-weighted levels. The 11.5 dB higher than A-weighted (standard...
The Community Noise and Health Study conducted by Canada included randomly selected participants aged 18–79 yrs (606 males, 632 females, response rate 78.9%), living between 0.25 11.22 km from operational wind turbines. Annoyance to turbine noise (WTN) other features, including shadow flicker (SF) was assessed. current analysis reports on the degree which estimating high annoyance (HAWTSF) improved when variables known be related WTN exposure were also considered. As SF increased [calculated...
Much has been achieved by research into ecological restoration as a nature-based solution to the destruction of ecosystems, particularly in Canada. We conducted national-level synthesis Canadian ecology understand strengths and gaps. This answers following questions: Who is studying restoration? What ecosystem types are studied? Where Which themes focused on? Why happening? And how monitored evaluated? employed systematic searching for this review. Our results show that mainly academics....
It has been extensively communicated that Health Canada's Community Noise and Study (CNHS) did not find positive associations between wind turbine noise (WTN) levels any of the evaluated health outcomes, beyond an increase in prevalence high annoyance toward several features. The authors emphasize this general conclusion remains bound by study strengths limitations. Following publication CNHS findings, there interest among some individuals to present alternative interpretations results...
The objective of the current paper was to characterize indoor wind turbine sound pressure levels (SPLs) assess audibility noise indoors, accounting for window opening, frequency spectra, and presbycusis. Loudspeaker generated used determine outdoor SPL differences at 11 representative dwellings using ISO 140-5:1998. procedure extended 16 Hz. With windows closed, broadband A- C-weighted SPLs were lower by 25.9 15.3 dB, respectively, spectra. opened, corresponding results 13.8 9.9...
Abstract Studies have yielded inconsistent evidence for an association between long-term average wind turbine sound pressure level (SPL) and disturbed sleep. Transient changes in sleep may be more susceptible to short-term variations SPL throughout the period time. We analyzed actigraphy data (participant nights = 2,094, males 151, females 192) 10 min intervals time-synchronized supervisory control acquisition. Calculated indoor was considered after adjusting rotor speed closed/open bedroom...
The Society for Ecological Restoration (SER) published the second edition of its International Principles and Standards Practice in 2019. We conducted a pan‐Canadian study using semi‐structured interviews with restoration professionals to explore extent which practitioners are aware document use it. Overall, we found that direct uptake by was lower than expected, approximately 37.7% all participants were both consulting publication guidance their practice ecological restoration. This is due...
