| 摘 要： | 本文在系统研究主动噪声控制技术和机动车辆内噪声来源的基础上，提出利用复合主动噪声控制思想，改善机动车辆室内噪声环境的方案及其算法实现。具体地说，就是利用反馈主动噪声控制系统，抵消低频噪声对车室内的总噪声辐射；利用前馈主动噪声控制系统，抵消发动机噪声的基频分量及其多次谐波分量。分析表明：该方案具有较好的除噪效果和较高的实用价值。

| Abstract: | This paper presents a scheme of reducing noises inside the automobile room by means of the Hybrid Active Noise Controlling.It bases on the systematic researches on the technology of active noise controlling and the analysis of noise sources inside the automobile room.The proposed scheme can attenuate the total noise radiation from low frequency noises when a feedback controller is used,and can also attenuate the base and harmonic frequencies of the engine noises when a feed forward controller is used.Analyses indicate that the presented scheme can reduce the automobile room noises effectively. |
