TLDR
The result of this study based on advanced sleep recording methodology together with extensive noise measurements in an ecologically valid setting cautiously suggests that there are no major changes in the sleep of participants who host new industrial WTs in their community.Abstract:
Wind is considered one of the most advantageous alternatives to fossil energy because of its low operating cost and extensive availability. However, alleged health-related effects of exposure to wind turbine (WT) noise have attracted much public attention and various symptoms, such as sleep disturbance, have been reported by residents living close to wind developments. Prospective cohort study with synchronous measurement of noise and sleep physiologic signals was conducted to explore the possibility of sleep disturbance in people hosting new industrial WTs in Ontario, Canada, using a pre and post-exposure design. Objective and subjective sleep data were collected through polysomnography (PSG), the gold standard diagnostic test, and sleep diary. Sixteen participants were studied before and after WT installation during two consecutive nights in their own bedrooms. Both audible and infrasound noises were also concurrently measured inside the bedroom of each participant. Different noise exposure parameters were calculated (LAeq, LZeq) and analyzed in relation to whole-night sleep parameters. Results obtained from PSG show that sleep parameters were not significantly changed after exposure. However, reported sleep qualities were significantly (P = 0.008) worsened after exposure. Average noise levels during the exposure period were low to moderate and the mean of inside noise levels did not significantly change after exposure. The result of this study based on advanced sleep recording methodology together with extensive noise measurements in an ecologically valid setting cautiously suggests that there are no major changes in the sleep of participants who host new industrial WTs in their community. Further studies with a larger sample size and including comprehensive single-event analyses are warranted.read more

TL;DR: Two pilot studies with the aim of examining the acoustical properties of wind turbine noise that might be of special relevance regarding effects on sleep indicated that amplitude modulation strength, spectral frequency and the presence of strong beatsmight be of particular importance for adverse sleep effects.

TL;DR: The present study does not support an association between nighttime WTN and adverse birth outcomes, however, there were few cases in the high exposure groups and the results call for reproduction.

Aslak Harbo Poulsen,Ole Raaschou-Nielsen,Alfredo Peña,Andrea N. Hahmann,Rikke Baastrup Nordsborg,Matthias Ketzel,Jørgen Brandt,Mette Sørensen +7 more
TL;DR: The present study does not support an association between WTN and redemption of antihypertensive medication, and the lack of association was consistent across sub-populations of people living on farms, far from major roads and with high validity of the noise estimate.

TL;DR: Findings support that K-complexes are a sensitive marker of sensory processing of environmental noise during sleep and that increased hearing acuity and decreased self-reported noise sensitivity increase K- complex probability.

Auditory and non-auditory effects of noise on health
Mathias Basner,Wolfgang Babisch,Adrian Davis,Adrian Davis,Mark Brink,Charlotte Clark,S.A. Janssen,Stephen Stansfeld +7 more
TL;DR: The importance of adequate noise prevention and mitigation strategies for public health is stressed, as Observational and experimental studies have shown that noise exposure leads to annoyance, disturbs sleep and causes daytime sleepiness.

TL;DR: In this paper, the authors stress the importance of adequate noise prevention and mitigation strategies for public health and stress that noise exposure leads to annoyance, disturbs sleep and causes daytime sleepiness, aff ects patient outcomes and staff performance in hospitals, increases the occurrence of hypertension and cardiovascular disease, and impairs cognitive performance in schoolchildren.
