摘　　要：归纳了一套简单易行的半经验噪声预估方程,可分别预测轴流风机的旋转噪声、宽频噪声和总声功率,并以T-40-NO3 1/2改型轴流通风机噪声测量结果进行了验证。A simple semi-empirical noise predicting equations are presented in this paper, which could be used respectively to predict rotating noise, wide-band Noise and total sound power level. A axial fan (T-40-No. 3 1/2) is experimentally messured and predicted by these equations the results are agreeable.
