| 摘 要： | 本文基于对车内噪声进行试验分析,提出了用微机、数字电路和少数声学元件等组成的车内闭环主动消声试验系统,并进行了系统配置和软件设计。在考虑实际系统中传递环节的同时,对威德罗(Widrow)提出的LMS算法做了改进。最后,给出了在不同转速下的试验结果。

| Abstract: | In this paper, noise in passenger compartment of vehicle is analysed.Furtherly, an active closed loop cancelling system is proposed using amicrocomputer, digital circuit and several acoustic elements. Also, har-dware and software of the system are designed. Considering the responsi-ng characteristics of the actual system, LMS algorithm developed byWIDROW is improved. Finally,the experimental results are presented atseveral certain speeds of the vehicle engine. |
