Wind turbine noise (WTN) exposure could potentially interfere with the initiation of sleep. However, effects on objectively assessed sleep latency are largely unknown. This study sought to assess the impact of WTN on polysomnographically measured and sleep diary-determined sleep latency compared to control background noise alone in healthy good sleepers without habitual prior WTN exposure.
Twenty-three WTN naïve urban residents (mean ± SD age: 21.7 ± 2.1 years, range 18-29, 13 females) attended the sleep laboratory for two polysomnography studies, one week apart. Participants were blind to noise conditions and only informed that they may or may not hear noise during each night. During the sleep onset period, participants were exposed to counterbalanced nights of WTN at 33 dB(A), the upper end of expected indoor values; or background noise alone as the control condition (23 dB(A)).
Linear mixed model analysis revealed no differences in log10 normalized objective or subjective sleep latency between the WTN versus control nights (median [interquartile range] objective 16.5 [11.0 to 18.5] vs. 16.5 [10.5 to 29.0] min, p = .401; subjective 20.0 [15.0 to 25.0] vs. 15.0 [10.0 to 30.0] min, p = .907).
Although undetected small effects cannot be ruled out, these results do not support that WTN extends sleep latency in young urban-dwelling individuals without prior WTN exposure.
接触风力涡轮机噪音（WTN）可能会干扰睡眠的开始。然而，其对客观评估的睡眠潜伏期的影响在很大程度上尚不清楚。本研究旨在评估与仅接触对照背景噪音相比，WTN对多导睡眠图测量的和睡眠日记确定的睡眠潜伏期的影响，研究对象为之前没有习惯性接触WTN的健康良好睡眠者。
23名之前未接触过WTN的城市居民（平均±标准差年龄：21.7±2.1岁，范围18 - 29岁，13名女性）参加了睡眠实验室的两项多导睡眠图研究，间隔一周。参与者对噪音条件不知情，只被告知他们在每个晚上可能会或可能不会听到噪音。在入睡期间，参与者在33 dB(A)（预期室内值的上限）的WTN环境下和对照条件（仅背景噪音，23 dB(A)）下进行了平衡的夜间睡眠。
线性混合模型分析显示，WTN组与对照组夜间睡眠的log10标准化客观或主观睡眠潜伏期没有差异（中位数[四分位间距]客观睡眠潜伏期：16.5[11.0至18.5]分钟对16.5[10.5至29.0]分钟，p = 0.401；主观睡眠潜伏期：20.0[15.0至25.0]分钟对15.0[10.0至30.0]分钟，p = 0.907）。
虽然不能排除未检测到的微小影响，但这些结果不支持WTN会延长未接触过WTN的年轻城市居民的睡眠潜伏期这一观点。
