| 摘 要： | 本文用混响室－消声箱法对具有不同几何和物理参数配置的弹性－粘弹性阻尼复合板传声损失（ＴＬ）进行了系统的实验测量。根据测量结果的分析,得到了有限尺寸阻尼复合板的结构参数变化对传声损失影响的规律,这些规律对于低噪声汽车设计中阻尼复合板隔声件的结构参数优化具有实际意义。

| Abstract: | In this paper, the measurement of sound transmission loss (TL) is carried out with "reverberant chamber-receiving box approach" for elastic - viscoelastic laminated damping panels (EVLDP) with varying geometric and physical parameters. Based on the analysis of the results, the dependence of the sound transmission loss characteristics on the structural parameters of EVLDP with finite size has been classified, which is helpful for the acoustic optimal design of automobile components made of EVLDP. |
