汽车噪音的来源：: [+ H; A4 [5 Q
-发动机的振动噪音、-变速器的振动噪音-路噪-发动机的空气传播噪音-排气管和喷射系统噪音-外部噪音（胎噪，其他车辆的噪音，风噪等）-噪音的处理方式
# F. }9 i5 q% K) L8 h. W4 B8 D6 r声音是一种机械波，这种机械波需要通过媒介把能量从一个地方传播到另外一个地方。声音的发生需要有两个因素，一个要有振动的物体，另外一个则需要媒介的传播，媒介可以是任何相联系的物体也可以是相互交叉的颗粒分子。也就是说声音可以在固体、液体或者是气体中传播。5 ~1 D/ D3 R* |9 o& b( X0 s8 w9 b
声音经过空气的传播可以覆盖整个车身，穿过车身进入车厢里的声音也是十分清晰的。

2) 止振材料：止振材料一般安装在车身内部，有以下益处; -吸收车身的振动噪音 -具有密封功能，防止车身腐蚀 -增加车身厚度和刚性，加强车身安全性能Q% {0 R+ q( k( n( N; q

4) 密封材料：# z# @% X8 E' o7 v* i- X
密封材料主要是用于密封电线的封口和车身内部的接触原件，减少传入车厢内的吱吱声。 安装程序和产品效果: , }& m5 G3 ?7 [" \/ U, f' X: @2 z% S
一般安装时会用到以下这些材料 -有自粘层的材料-需要使用喷枪安装的乳香脂的液体材料。-隔音材料的施工组合因每一辆车的型号不同而有所不同。我们建议您在决定给您的爱车施工隔音材料之前，一定要先咨询当地的经销商，为您的车量身定制最适合的隔音方案！ 需要注意的是：由于声音传播的特性（可以通过任何媒介传播），理论上说噪音是很难被完全消除的-只有在真空的条件下声音才不会传播。STP通过不同材料的有效结合，以及正确的施工手法可确保减少60%左右的噪音，另外还有以下益处:

This material is well suited for usage in the engine compartment due to the outer layer that is both oil and gasoline resistant. This layer also reflects the heat from the engine significantly reducing the amount of it transferred into the passenger compartment of the vehicle. This material also features a very strong sound absorption necessary to reduce the noise from the engine.
