用声强法对轴流通风机噪声场的实验研究

Experimental Study on Aerodynamics Noise of Axial-Flow Fans with the Sound Intensity Method

首次应用声强测量技术于轴流风机噪声场的测定,并进行了实时分析,得出了与理论分析一致的结果。

Sound intensity method is first used in this paper to messure the noise field of axial fans and messurement result of this method are in good agreement with theoretical analysis.
