| Abstract: | 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. |

| Keywords: | urban mass transit vehicle sound transmission loss equivalent transmission |
