摘　　要：提出了一种结合解析法和优化算法两种解决方案的次级声源优化策略,建立了局部有源静音区声场模型,得到了次级声源布放位置与声场分布函数的关系。The optimal strategy of secondary sound source is presented, which combines the analytical method with the optimization algorithm. The sound field model of partial active quiet zone is esteblished. The relation between the secondary sound source location and the sound field distribution function is acquired.

关 键 词：有源噪声控制 次级声源 遗传算法
