濟南汽車隔音http://www.szanyuda.com/減噪工程是音響改裝的車基本上都有做隔音處理，可隔音材料在品質(zhì)上和價位上是有很大差異的，制振減振材料和可吸收大量中低頻噪的材料，前者是制振板，后者是低頻吸音材料。制振板的主要作用是降低汽車內(nèi)部因鋼板共振差生的噪音，這些噪音主要集中在后行李箱、車箱底部、四個門。
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.

濟南汽車隔音http://www.szanyuda.com/分析好的制振板是由阻尼膠加上一層鋁鉑制成，而普通的制振板是由瀝青加一層少量的鋁鉑制成，制振板效果阻尼膠加鋁鉑是普通材料的4倍。吸音材料同樣也有很大的差異。好的中低頻吸音材料是由四層聲學晶體結(jié)構(gòu)組成。能大量阻隔發(fā)動機和排氣管車內(nèi)傳遞的熱量和噪音，而普通吸音材料就無法做到。另外好的制振板和吸音材料具備優(yōu)秀的抗老化能力，且不會隨著溫度的變化對車內(nèi)造成任何的污染，而普通材料中的瀝青隨溫度變化會產(chǎn)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.
