| 摘 要： | 利用信号分析的理论，通过建立“虚拟系统”，分析了整体车身腔体的“综合传递函数”；并利用频谱分析技术对轻型客车车内噪声进行测试、分析，试验表明解决车内噪声关键是降低车内低频噪声，而车身腔体结构又是影响车内噪声，特别是低频噪声的关键因素之一。

| Abstract: | On the base of virtual system, integration transfer function of light bus was measured. And then by means of the techniques of spectrum analysis, the noise inside a light bus was measured and analyzed. In order to decrease inner, controlling low frequency noise inside light bus is the key. The structure of light bus is a key factor. |
