自由声场自适应有源噪声控制中误差传感器的布放

Arrangement of Error Sensors for Adaptive Active Noise Control in Free Sound Field

合理地布放误差传感器可以减小自适应有源噪声控制系统的复杂性，提高降噪量。本文研究了自由声场条件下误差传感器布放与ＡＡＮＣ系统降噪效果的关系，从理论和实验两个方面总结了自由场误差传感器布放规律。

It is very important to arrange appropriately the error sensors for Adaptive Active Noise Control(AANC).In this paper,the relationship between the error sensor arrangement and noise the reduction in free sound field is theoretically and experimentally examined.A general rule of the error sensor arrangement is investigated.
