中文摘要：
探讨风力机噪声的传播问题,推导了噪声随距离分布的数学关系。由于噪声的接受者一般位于地面,以接受者到塔架的距离作为自变量来分析噪声传播特征。继而应用CadnaA软件进行噪声仿真预测,将数学推导结果与仿真结果进行比较,结果显示了良好的一致性。
英文摘要：
The problem of wind turbine noise emission and propagation is discussed,and the mathematical relationship between noise intensity and distance is formulated.Since the noise recipients are generally located on the ground,the distance from the recipient to the wind turbine tower can be regarded as the independent variable to analyze the characteristics of noise propagation.Then,the noise is predicted numerically using software Cadna A.Results of mathematical derivation are compared with the simulation results,and both results are found to be in a good agreement.
