降低汽车噪音的方法探析
摘要：汽车是现代交通工具中最为普遍也是最重要的一种，随着人们对生活要求的提高，对汽车的需求也从最初的代步工具逐渐上升为舒适的移动空间。由于汽车噪音在行驶过程中给车内人员带来很大的影响，直接关系到车内人员的健康。所以，汽车噪音就成为了衡量汽车自身机械性能和舒适性能品质的重要标准。
近些年来，随着人们对汽车乘坐舒适性要求的提高和人们环保意识的加强，各国对汽车噪音的要求也越来越严格。改善车辆内部声学环境，降低车内噪音水平，是各国政府和车辆生产厂家共同关注的问题，汽车车内噪音的研究已受到普遍重视。本文对噪音产生的原因进行了分析，并对降低汽车噪音的方法进行探讨。

Abstract：The car is a modern means of transport is the most common and most important kind of life, the demand for cars gradually increased from the original means of transport for comfortable mobile space. Vehicle noise to the occupants in the process of moving a great deal of impact is directly related to the health of the occupants. Therefore, the vehicle noise has become an important criterion to measure the car’s own mechanical properties and comfort performance quality.
In recent years, with the strengthening of to improve vehicle ride comfort requirements and people’s environmental awareness of the national vehicle noise requirements become increasingly stringent. Improve vehicle interior acoustic environment, reduce interior noise levels, the issues of common concern of Governments and vehicle manufacturers, automotive interior noise has attracted universal attention. In this paper, the noise causes were analyzed, and to explore methods to reduce vehicle noise.
