Abstract – 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 . . .More »
Highlights We identified all Danes exposed to wind turbine noise (WTN) from 1982 to 2013. We then identified all live born singletons from mothers in this population. We investigated preterm birth, low birth weight and small for gestational age. We found no associations between WTN and the adverse birth outcomes. Few women had high levels of WTN and independent replication is called for. Abstract Noise from wind turbines (WTs) is reported as more annoying than traffic noise at similar levels, . . .More »
Wind turbine low frequency and infrasound propagation and sound pressure level calculations at dwellings
Abstract – This study was developed to estimate wind turbine low frequency and infrasound levels at 1238 dwellings in Health Canada’s Community Noise and Health Study. In field measurements, spectral peaks were identifiable for distances up to 10 km away from wind turbines at frequencies from 0.5 to 70 Hz. These measurements, combined with onsite meteorology, were in agreement with calculations using Parabolic Equation (PE) and Fast Field Program (FFP). Since onsite meteorology was not available for the Health Canada study, PE . . .More »
Highlights The importance to consider noise annoyance in legislation is discussed. Conversion curves for equally highly annoyed [HA] by different sources are presented. A wind turbine noise limit of 43.1 dB(A) is derived from the conversion curves. The limit is based on %HA and results are comparable with some international standards. Abstract 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, . . .More »
