摘要
针对主动噪声控制技术在改善机动车辆舱室内噪声状况的应用中存在的技术难点,如消除声反馈过程、准确获得参考信号和声学路径的估计等,进行了分析、研究,并在此基础上给出了一种机动车辆舱室内的主动噪声控制系统设计方案。
This paper presents a scheme of reducing noises inside the automobile room by means of the active noise control. It bases on the resolving of three crucial problems in system implementation, which are eliminating acoustic feedback process, obtaining exact reference signals and estimation of acoustic paths.
