This paper presents results from a one-year study of indoor annoyance and self-reported sleep times for two participants located near different wind farms. Continuous measurements outdoor noise meteorological conditions were taken at each location the duration study. In least 50% recordings, described as "swish" or "swoosh." Furthermore, majority recordings occurred nighttime in early morning. The third quartile A-weighted sound pressure level [SPL(A)], between 27 31 dBA, was associated with an 88% increased probability compared to lowest reference quartile, which 12 22 dBA [odds ratio 95% confidence intervals, 7.72 (2.61,22.8), p < 0.001]. SPL(A) also predictive but only 40 45 dBA. prevalence amplitude modulation (AM), defined percentage time that AM detectable by algorithm period, annoyance. Self-reported efficiency (time spent asleep relative bed available sleep) significantly (β = -0.66, 0.02) explained small fraction variance (R2 5%).
