提出了一种稳健的全波数空间声场重构技术,适用于分析任意形状物体的声辐射.根据波叠加积分公式,由实际声辐射体产生的空间声场可以由置于辐射体内部的虚构源产生的声场来等效替代,而虚源上的源强密度可以通过匹配有限个场点上的声压来获得,进而可以得出任意场点的声学信息.
A robust full-wave space acoustic reconstruction technique is proposed, which can be used to analyze the acoustic radiation of arbitrary shape objects. According to the wave superposition integral formula, the spatial sound field generated by the actual acoustic radiator can be generated by the fictitious source placed inside the radiator Of the sound field to replace the equivalent, and the source of the virtual source density can be obtained by matching the sound pressure on a limited number of field points, which can be obtained at any site acoustic information.
