基于ANC的非入耳式汽车主动降噪技术应用研究

Application Research of Non-in-ear Vehicle Active Noise Reduction Technology Based on ANC

汽车的静音性能主要依靠降噪手段来实现,包括主动降噪和被动降噪。文章对非入耳式ANC主动降噪技术在汽车上的应用展开分析,着重分析降噪原理和实现手段,并以长安福特锐界车型为例介绍该技术在实车上的应用。

With the development of technology,the automobile is not only a simple means of transportation,but also a mobile home or office.Therefore,the comfort and quietness of the automobile have attracted the attention of consumers.The quiet performance of automobile is mainly realized by means of noise reduction,including active noise reduction and passive noise reduction.This paper analyzes the application of non-in-ear ANC active noise reduction technology in automobiles,focuses on the analysis of the principle and implementation means of noise reduction,and introduces the application of this technology in real cars by taking Changan Ford Ruijie model as an example.
