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

Health Effects Related to Wind Turbine Sound, Including Low-Frequency Sound and Infrasound
TL;DR: In this paper, a narrative review of observational and experimental studies was conducted to assess the association between exposure to wind turbine sound and its components and health effects in the general population, concluding that wind turbines lead to a higher percentage of highly annoyed when compared to other sound sources.

Understanding stress effects of wind turbine noise – The integrated approach
TL;DR: In this paper, the authors combined the methodology of stress psychology with noise measurement to an integrated approach to better understand causes and effects of wind turbine (WT) noise, and found that more residents complained about physical and psychological symptoms due to traffic noise (16%) than to WT noise (10%, two years later 7%).

TL;DR: There is an extensive and diverse body of evidence around health impacts of wind turbines in residential settings, showing particularly noise consequences concerning increased noise annoyance with its complex pathways; no relationship between wind turbine noise and stress effects and biophysiological variables of sleep; and heterogeneous findings concerning sleep disturbance, quality of life, as well as mental health problems.

A field study of effects of road traffic and railway noise on polysomnographic sleep parameters.
TL;DR: Findings that railway noise has a stronger impact than road traffic noise on physiological parameters during sleep, and that the maximum noise level is an important predictor of noise effects on sleep assessed by PSG are supported, at least for railway noise.

Nocturnal aircraft noise exposure increases objectively assessed daytime sleepiness
TL;DR: In this article, the authors investigated the effects of noise exposure on sleep in a polysomnographic laboratory study and found that sleepiness levels increased significantly with the number of noise events (p = 0.021), with the maximum sound level of noise, and with the equivalent continuous noise level.

The impact of psychological factors on self-reported sleep disturbance among people living in the vicinity of wind turbines.
TL;DR: Evidence is provided for the role of individual differences and psychological factors in reports of sleep disturbance by people living in the vicinity of WTs and whether participants reported poorer sleep quality if they had a negative attitude to WTs,If they had concerns related to property devaluation, and if they could see turbines from their properties.
