3M Thinsulate 吸音棉
1. 优越的吸音功效（尤其是中高音，如风燥声）
2. 有隔热效果 （适合安装在顶棚)
3. 轻 （不会显著增加油耗）
4. 可压缩 （能安装在窄的地方如门板）
5. 不吸水 （不需害怕发霉或异味）
6. 容易裁剪与黏贴 （只需用普通剪刀剪，用热熔胶或双面胶粘）
可安装部位：
1. 门板
2. 底盘
3. “香蕉叶”
4. A，B，C柱
5. 车尾箱
6. 顶棚
配套1：3M Thinsulate TAI-4047 (23mm, 420g/m2) 3m x 1.5m x 23mm = RM250
没散买
如果是要邮寄，有Poslaju邮寄服务，但邮费由买家付。
*厚度是厂商提供的数据，真正产品可能因压缩而显得比较薄。
四门大概用 2m x 1.5m
底盘大概用 2.5m x 1.5m
车尾箱大概用 1.5m x 1.5m
A，B，C柱及香蕉叶大概用 1m x 1.5m
顶棚大概用 2m x 1.5m
加入一些汽车隔音的知识：
There are 2 types of noise:
1)Structure-borne noise (Noise that travels in vehicle structure)
2)Airborne noise (Noise that travels in air)
Example of structure borne noise:
Consider an running engine as a source of vibration. When an engine is running, the vibration will propagate over the whole car structure, such as roof, door panels, etc. The vibrating roof, door panels will transfer energy into air inside the car cabin, and then generate noise.
Example of airborne noise:
Consider an running engine as a source of noise. The noise will propagate through the air and get into cabin through holes or leakage and across the surface of car structure.
There are 4 major ways to soundproof your car:
1) Isolation - reduce transmission of vibration energy (Structure borne noise)
Eg: Engine mount, suspension bush,etc
2) Damping - dissipate vibration energy into heat (Structure borne noise)
Eg: Constrained Layer Damper (CLD) like STP Gold, Dynamat Xtreme, etc
3) Barrier - reduce transmission of sound energy (Airborne noise)
Eg: Mass Loaded Vinyl (MLV) like Dynamat Dynapad, CAE VB-4, etc
4) Absorption - dissipate sound energy into heat (Airborne noise)
Eg: 3M Thinsulate, STP Biplast, open-cell foam, etc
To effectively soundproof your car, you need to use different types of material to tackle the noise. 3M Thinsulate sold here is one of the noise absorption material. Depending on area of treatment, you will get better result by combining 3M Thinsulate with CLD or/and MLV.
A very common example:
You have put on CLD like STP iSilver all over your door, floor, and roof (close to 100% coverage). The car become quieter but you still can hear noise like wind noise. CLD only reduces vibration of car structure, hence reducing structure borne noise. Wind noise will still get into cabin through gap between doors, hollow car structure, tiny gap at door handle, etc. Wind noise will also get into cabin through windows due to its low sound transmission loss. However, we are unable to treat the glass. But you can treat the door area by putting a layer of sound absorbing material behind door panel to absorb the wind noise. You can also put a heavy layer of MLV (high sound transmission loss) to block the noise if you don't care about the extra weight added to the doors.
