摘要
针对主动噪声控制技术在抵消封闭空间中发动机噪声这一应用 ,在对主动噪声控制系统实现中存在的几个关键难题进行探讨、研究的基础上 ,给出了消除声反馈过程。
Aimed at the application of active noise controlling technology in engine noise cancellation in a close space and based on the discussion of the crucial problems in the implementation of Active Noise Controlling System, this paper presents a solution to eliminate acoustic feedback process, to obtaining exactly reference signals and to estimate the acoustic paths, etc.
