Each channel remains at an assigned frequency within a single band. 每个信道在单一的频段内保持分配的频率。
Simulation results for the structural acoustical coupling in enclosed space show that the structure-brone noise can be reduced effectively in assigned frequency band, the maximum control value for noise peak value is near 20 dB ( A). 封闭空间结构振动声耦合反馈力控制仿真结果表明:通过合理选择性能加权函数,噪声可以在指定频带得到良好的控制,最大噪声峰值近20dB(A)。
