| 摘 要： | 对一种ANC(自适应噪声抵消)的主动降噪技术进行了讨论和研究。论述了基于LMS的ANC系统的基本原理,在此基础上设计了反馈式ANC系统。与前馈式ANC系统相比,反馈式ANC系统的消噪能力和收敛速度均优于前馈式ANC系统,通过MATLAB仿真,结果与理论分析是一致的。 |

| Abstract: | A study about the ANC using in digital noise cancellation earphone is progressed.The basic principle of ANC based on LMS algorithm is introduced,on which the feedback ANC system is designed.Comparing to the feedforward ANC system,the feedback ANC system has a better effect and a faster convergence velocity.MATLAB simulation results are given,which are coincident with the theoretic analyzing well. |
