摘　　要：通过理论计算和实验方法对城轨车辆整车隔声设计进行研究,结果表明:车内噪声水平不仅受到车辆隔声性能影响,还与车辆运行环境相关,在整车隔声设计中应当遵循"等效透射"原理。This paper analyzes and researches the holistic sound insulation design of urban mass transit vehicles through theoretical calculations and experiments.The results show that not only the vehicle＇s sound insulation property,but also the running environment effects the level of vehicle interior noise.The principle of equivalent transmission should be followed during the holistic sound insulation design.

关 键 词：城轨车辆 隔声量 等效透射
