摘　　要：某在开发车型主观评价存在低频轰鸣噪声抱怨,通过进行系统的声学故障测试分析,确定主要原因是进气噪声引起的。通过在进气系统管路上增加一个赫姆霍兹谐振腔降低进气系统噪声,有效降低了该低频轰鸣声抱怨,车辆乘坐舒适性明显提高。The systemic test and analysis show the booming noise take system. By optimization of the intake system, adding one Helmholtz level is greatly decreased and the comfort is also obviously improved. is much related with the in- resonator, t]he interior noise
