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

调幅风电场噪声与烦恼的关系:为期一年的实地研究

本文介绍了对位于不同风电场附近的两名参与者的室内烦恼和自我报告的睡眠时间进行的为期一年的研究结果。在研究期间,对每个地点的室外和室内噪声和气象条件进行了连续测量。在至少 50% 的烦恼录音中,参与者将噪音描述为“嗖嗖声”或“嗖嗖声”。此外,大多数烦恼录音发生在夜间和清晨。A加权室内声压级 [SPL(A)]的第三个四分位数,介于 27 到 31 dBA 之间,与最低参考四分位数(介于 12 到 22 dBA 之间)相比,烦恼的可能性增加了 88%。比率和 95% 置信区间,7.72 (2.61,22.8),p< 0.001]。室外 SPL(A) 也可预测烦恼,但仅在 40 到 45 dBA 之间。幅度调制 (AM) 的室外流行率,定义为算法可检测到每个烦恼时段 AM 的时间百分比,也与烦恼有关。自我报告的睡眠效率(睡眠时间相对于可用于睡眠的床上时间)与夜间烦恼显着相关(β  = -0.66,p  = 0.02),但仅解释了一小部分方差(R 2  = 5%) .
