Health effects of ultra-low frequency sound and noise by wind power generation facilities

Author:  Ishitake, Tatsuya

We investigated whether long-term exposure to low-frequency noise generated by wind power facilities is a risk factor for sleep disorders. We performed an epidemiological study of the living environment and health effects of such noise by surveying 9,000 residents (≥20 years of age) living in areas with operational wind power facilities. Sleep disorders were assessed using the Athens Insomnia Scale. To assess environmental noise in residential areas near wind turbines, infrasound and low-frequency sound exposure levels were measured at 50 community centers of a town. The prevalence of sleep disorders was significantly higher among residents who reported subjectively hearing noise (by approximately twofold) than among those who did not. Moreover, the reported prevalence of sleep disorders was significantly higher (by approximately twofold) among residents living at a distance of ≤1,500 m from the nearest wind turbine than among residents living at a distance of ≥2,000 m, suggesting a dose-response relationship. The attitudes of residents towards wind power facilities strongly affected their responses regarding sleep disorder prevalence. It is highly likely that audible noise generated by wind power facilities is a risk factor for sleep disorders. Obtaining a satisfactory consensus from local residents before installing wind power facilities is important as for more amenable their attitudes towards such facilities. [Article in Japanese]

Pregnancy exposure to wind turbine noise and adverse birth outcomes: a nationwide cohort study

Author:  Harbo Paulsen, Aslak; et al.



Noise from wind turbines (WTs) is reported as more annoying than traffic noise at similar levels, raising concerns as to whether WT noise (WTN) may negatively affect health, as reported for traffic noise. We aimed to investigate whether residential WTN is associated with adverse birth outcomes. Based on national registries, we identified all Danish dwellings situated within ≤ 20 wt heights radius and a random selection of 25% of dwellings situated within 20–40 wt heights radius of a WT. We identified 135,795 pregnant women living in the dwellings from 1982 to 2013, and collected information on gestational age and birth weight from a national birth registry. Using data on WT type and simulated hourly wind at each WT, we estimated hourly outdoor and low frequency (LF) indoor WTN at the dwellings of the pregnant women and aggregated as mean nighttime WTN during pregnancy. We used logistic regression with adjustment for individual and area-level covariates for the analyses. We did not find evidence suggesting that mean pregnancy or trimester-specific exposure to outdoor or indoor LF WTN were associated with any of the three adverse birth outcomes investigated: preterm birth (n = 13,003), term small for gestational age (n = 12,220) or term low birth weight (n = 1127). However, the number of cases in the highest exposure categories of ≥  42 dB outdoor WTN or ≥ 15 dB indoor LF WTN were low for all outcomes (n between 0 and 31). 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.

A procedure for deriving wind turbine noise limits by taking into account annoyance

Author:  Fredianelli, Luca; et al.



With the increasing installation of wind farms, the attention of citizens towards wind turbine noise (WTN) has grown. Differently from some national legislations, the scientific community has promptly responded, increasing the studies and the social surveys in order to better understand the cause of disturbance and the indicators that relate to it. At first, the paper underlines the importance of low WTN levels for indirect health effects such as sleep disturbance and annoyance. The importance to consider noise annoyance in legislation is also discussed, as WTN is more disturbing than other most common noise sources. Then, conversion curves for equally highly annoyed are introduced considering the annoyance perceived by population in relation with the type of source. Finally, a specific limit value of 43 dB(A) for WTN is derived and suggested, comparable with British and Danish standards.

Environmental Noise Guidelines for the European Region

Author:  World Health Organization

Wind Turbine Noise Recommendations

For average noise exposure, the GDG [Guideline Development Group] conditionally recommends reducing noise levels produced by wind turbines to below 45[A] dB Lden* [at the most exposed façade, outdoors], as wind turbine noise above this level is associated with adverse health effects.

To reduce health effects, the GDG conditionally recommends that policy-makers implement suitable measures to reduce noise exposure from wind turbines in the population exposed to levels above the guideline values for average noise exposure. No evidence is available, however, to facilitate the recommendation of one particular type of intervention over another.

*ISO 1996-1:2016 Section 3.6: Lden is the average of all (12-15 hours of day, 4 hours of evening [if defined], 8-9 hours of night) levels, with evening and night levels weighted: +5 dB added to the evening levels and +10 dB to the night levels.
