济南汽车隔音http://www.sdcarmusic.com/减噪工程是音响改装的车基本上都有做隔音处理，可隔音材料在品质上和价位上是有很大差异的，制振减振材料和可吸收大量中低频噪的材料，前者是制振板，后者是低频吸音材料。制振板的主要作用是降低汽车内部因钢板共振差生的噪音，这些噪音主要集中在后行李箱、车箱底部、四个门。
Jinan car noise reduction project is the audio conversion car basically do soundproofing treatment, insulation materials is a big difference in terms of quality and price, the system vibration damping material and can absorb a lot of the low-frequency noise in the material, The former is a damping plate, which is the low-frequency sound absorbing material. The main role of the system is to reduce the vibration plate steel automotive interior resonance due to poor students of noise, the noise is mainly concentrated in the trunk, the bottom of the trunk, four doors.

Jinan good car sound system analysis by damping vibration plate is coupled with a layer of aluminum foil made of plastic, while the ordinary damping plate is made of a layer of asphalt plus a small amount of aluminum foil, plastic damping effect of damping plate platinum Alcan is four times that of ordinary materials. There are also sound-absorbing material is also very different. Good low-frequency acoustic sound-absorbing material is composed of four crystal structures. Can be a lot of heat and noise barrier engine and exhaust pipe passing car, while the average sound-absorbing material can not be done. Another good damping panels and sound-absorbing material with excellent resistance to aging and does not change with temperature cause any pollution to the car, while the ordinary bituminous material with temperature changes will have some formaldehyde contamination.
