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, increasing the studies and the social surveys in order to better understand the cause of disturbance and the indicators that relate to it. At first, the paper underlines the importance of low WTN levels for indirect health effects such as sleep disturbance and annoyance. The importance to consider noise annoyance in legislation is also discussed, as WTN is more disturbing than other most common noise sources. Then, conversion curves for equally highly annoyed are introduced considering the annoyance perceived by population in relation with the type of source. Finally, a specific limit value of 43 dB(A) for WTN is derived and suggested, comparable with British and Danish standards.
随着风力发电场的日益增多，市民对风力涡轮机噪声（WTN）的关注也在增加。与一些国家的法规不同，科学界迅速做出了回应，增加了研究和社会调查，以更好地了解干扰的原因及其相关指标。首先，本文强调了低 WTN 水平对间接健康影响（如睡眠干扰和烦恼）的重要性。还讨论了在法规中考虑噪声烦恼的重要性，因为 WTN 比其他常见的噪声源更具干扰性。然后，引入了同等高度烦恼的转换曲线，考虑了人群对与源类型相关的噪声烦恼的感知。最后，推导出并建议了 WTN 的特定限值 43 dB(A)，与英国和丹麦的标准相当。
