摘　　要：以对某款轿车进气噪声优化为例,介绍了如何通过以改变进气管长度的方式,衰减进气谐振器都难以消除的50-100Hz的进气口低频噪声,并通过GT-POWER模拟计算进气系统的插入损失,得到调整进气管长度对进气噪声影响的规律,最后进行实车验证,车内噪声得到良好改善。With intake noise optimization of a passenger car as example, the air duct length is changed to attenuate low- frequency noise as 50-100Hz which is difficult to eliminate by resonator. And a law of adjustment impact on the intake noise of the air duct length is obtained by simulation insertion loss of the intake system based on GT-POWER, finally interior noise is improved by real test.
