| 摘 要： | 根据声学波动理论，首先提出了封闭空间内对单极子声源的局部有消声方法，指出当次级声源与传声器距离较近时才能达到较好的消声效果。在此基础上，对多次级声源共同作用时，各次级源强度及消声效果进行了推导。

| Abstract: | According to wave acousda theory, local aontrol of enclosed souod fields by monopole source is proposed. Large attenuation level can be acquirted when the seondary sourc is closed to the monitor. On the base of one seondary soume control theory, multi-secondary sources control theory is deduoed. The optimal secondary strengths are deduced also . By the end of this article the simulation results are given outand lay a foundation for the design of active noise controlling system. . |
