    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.

    济南汽车隔音http://www.sdcarmusic.com/分析好的制振板是由阻尼胶加上一层铝铂制成,而普通的制振板是由沥青加一层少量的铝铂制成,制振板效果阻尼胶加铝铂是普通材料的4倍。吸音材料同样也有很大的差异。好的中低频吸音材料是由四层声学晶体结构组成。能大量阻隔发动机和排气管车内传递的热量和噪音,而普通吸音材料就无法做到。另外好的制振板和吸音材料具备优秀的抗老化能力,且不会随着温度的变化对车内造成任何的污染,而普通材料中的沥青随温度变化会产生一定的甲醛污染。
    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.
