本系统地总结了近几年来国内外在结构诱发声有源控制研究方面所取得的进展。讨论了自由声场结构辐射/透射声的有源控制;在存在内部噪声源或外力激励弹性结构条件下的封闭空间声场有源控制。比较了声控制和力控制方式有源控制机理及控制效果的影响。最后,对三维空间声场有源控制的进一步发展提出看法。
This article systematically summarizes the progress made in the research of structure-induced acoustic active control at home and abroad in recent years. The active control of the radiated / transmitted sound of the free sound field structure is discussed. The closed-space active field control of the sound field in the presence of an internal noise source or an external force-activated elastic structure is discussed. The effects of the active control mechanism and control effect of the acoustic control and force control are compared. Finally, the author puts forward some suggestions on the further development of active control of sound field in 3D space.
