摘要
运动声源的准确识别是对其进行有效控制的重要前提,本文在近场声全息理论基础上,利用时域多普勒效应消除原理、球面波传播原理,建立了用于运动噪声源识别的动态识别方法。模拟计算和实车试验证明该识别方法能对高速运动噪声源进行准确识别。
The precondition of moving noise control is to identify the moving source accurately. Based on the nearfield acoustic holography, the dynamical moving sound source identification method is developed by using the time domain de-dopplerization theory and the spherical wave theory. The stimulation and experiments results prove the validity of the method.
