摘要

调幅增加了风力机噪声带来的烦恼。当在测量或计算的时间平均声级上增加一个惩罚时，人们会得到更好的烦恼。调幅风电机组噪声由脉冲组成。它们都具有短时平均声级和调制深度的特征。后者决定脉冲惩罚。本文给出了在短时间平均声级和各脉冲惩罚已知的情况下，如何计算调幅式风力机噪声的改进噪声。讨论了同脉冲的一种特殊情况。所提出的方法需要通过研究加以检验。

Proposed Methodology for the Annoyance Penalty of Amplitude Modulated Wind Turbine Noise

Amplitude modulation increases the annoyance caused by wind turbine noise. One gets the improved annoyance when a penalty is added to the measured or calculated time-average sound level. The amplitude modulated wind turbine noise consists of pulses. Each of them could be characterized by the short time-average sound level and the modulation depth. The latter determines the pulse penalty. This paper shows how to calculate the improved annoyance of amplitude modulated wind turbine noise, when the short time-average sound level and the penalty for each pulse are known. A special case of identical pulses is discussed. The proposed methodology needs to be tested by research.
