摘要
有源噪声控制技术是目前国内外噪声控制界的研究热点。对有源噪声控制的概念、原理和实现作了介绍。根据有源控制方法对于低频噪声控制的优势,结合车内噪声的特点和现代控制领域的理论发展,讨论了在车内应用有源噪声控制技术的可行性,提出了一条可行的技术路线。
Active noise control （ANC） technology has become a research focus in noise control field. This paper made an introduction about the concept,theory and realization of ANC. According to ANC＇s advantage in low-frequency noise and the quality of automobile interior noise, based on Modem control theory＇s development, the feasibility of applying ANC in automobile cabins.A possible technical method for ANC in automobiles was given.
