摘　　要：空气滤清器系统做为发动机进气系统的重要零部件,其不仅影响着发动机系统的进气效率,功率,扭矩等,更重要的在于它还是整车的噪声源之一,影响着整车的内噪声和通过噪声。随着汽车在我国的大规模普及,其已日渐成为生活中不可缺少的代步工具,因此人们对汽车本身的噪声和舒适性要求越来越高,做为噪声源之一的空气滤清器系统的噪声研究就显得特别重要,本章内容将具体说明如何基于噪声控制进行空气滤清器的设计开发。Air induction system is a very important part of engine, it affect air induction efficiency ,power and torque performance of engine, and more important it is one of noise source of vehicle. Affect the interior noise and pass-by noise. As more and more people will be have car in the future, it is become a requisite for ride instead of walk, so they care more about noise and comfort of vehicle, so it is very important to research the noise of air induction system. We will use specific example to explain the method of air induction system noise control.

关 键 词：空气滤清器 噪声控制 噪声阶次分析方法
