In this paper near-field acoustic holography (NAH) is introduced into noise sources identification and localization, The theoretical analysis and the numerical simulation of different kinds of noise sources show: that in the case of complex sound sources, they can be identified and localized correctly, moreover, their vibration amplitude can be recognized very well.
将近场声全息(NAH)用于噪声源的识别和定位,对不同类型噪声源的数值模拟结果和理论分析表明:对于复杂声源,采用近场声全息方法可以精确地定位噪声源,并且能很好地分辨出各噪声源振幅的强弱;在波数域加窗滤波后,声压测量的误差对声源识别结果的影响不大。
