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.

据报道，风力涡轮机（WTs）产生的噪声比交通噪声在类似水平上更令人讨厌，这引起了人们对WT噪声（WTN）是否会对健康造成负面影响的担忧，如交通噪声所报道的那样。我们旨在调查居住的WTN是否与不良的出生结局有关。根据国家注册管理机构，我们确定了位于≤20 wt％半径内的所有丹麦住所，并随机选择了位于WT半径20–40 wt％内的25％的住所。我们确定了1982年至2013年居住在这些住所中的135795名孕妇，并从国家出生登记处收集了有关胎龄和出生体重的信息。使用有关WT类型的数据和每个WT的模拟每小时风速，我们估算了孕妇住所的每小时室外和低频（LF）室内WTN，并将其汇总为怀孕期间的平均夜间WTN。我们使用逻辑回归对个体和区域水平协变量进行了调整以进行分析。我们没有发现证据表明，在室外或室内LF WTN中平均怀孕或特定于妊娠期的暴露与所调查的三个不良出生结局中的任何一个有关：早产（n = 13,003），小胎龄（n = 12,220）或术语低出生体重（n = 1127）。但是，对于所有结局，≥42 dB的室外WTN或≥15 dB的室内LF WTN的最高暴露类别的病例数对于所有结局都是很低的（n在0到31之间）。本研究不支持夜间WTN与不良出生结局之间的关联。然而，
