摘要
阐述了风力机噪声的传播、衰减和针对噪声的评估准则,以及风力机噪声的测量原理。针对风力机噪声测量测点布置进行了优化,给出了风力机噪声的测量实验方案和装置,并且采用自由声场法对风力机噪声进行了测量,得出了风力机噪声和周围环境噪声之间的合成声压级。
The spread of wind turbine noise, attenuation and the assessment criteria for wind turbine noise, as well as the measurement principle was described. The measuring point for the wind turbine noise was optimized arrangement, the program and devices for the measurement were given, and the free sound filed method was adopted to measure the wind turbine noise. The synthesis sound pressure level between wind turbine noise and ambient noise was derived.
