摘要
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。
In this paper,advances in active control of structure-induced sound are summarized.Firstly,active control of free-field noise raditated /transmissed by structure vibration and enclosed space field noise generated by the Inner noise sources and the external forces are discussed.Secondly,physical mechanism and effects for active control of sound by sound sources and force sources are compared,and finally,the current trends in research and application are presented in the conclusion remarks.
