济南汽车隔音http://www.sdcarmusic.com/介绍汽车机舱内各部位噪音源不同，施工时要注意材料选用得当，由于不同车型所需材料数量不同，在此，以三厢车为例，降噪材料以460mm*860mm为规格，说明个部位所用料及数量。
Jinan car noise introduced various parts of the car cabin noise source is different, pay attention to proper selection of the construction materials, due to the number of different models in different materials required in this, with the sedan, for example, noise reduction materials to 460mm * 860mm as standard, explain a portion of the materials and quantity.
  
济南汽车隔音谈到叶子板和防火墙以发动机噪音和路噪为主，因此，需要使用止震板（止震材料）和吸音材料。前叶子板共需要3张止震板和3张吸音棉。车门隔音，每门需要2张止震板，共8张止震板。当然，每门在止震板纸上加上一张吸音棉，效果更佳，考虑到材料厚度以及车门板内饰的空间问题，各车可适当加或者不加吸音棉。 后备箱以及后轮毂在传播低频噪音之外，还形成共鸣加大噪音度，为此，需要先使用止震材料，在此基础上再贴上吸音棉。共需要8张止震板和8张吸音棉。
Jinan car sound comes to the fender and firewalls to engine noise and road noise, hence the need to use only shock board (only shock material) and sound-absorbing material. Front fender require a total of three dead and three shock-

absorbing cotton board. Soundproof doors, every door needs two stop shock board, a total of eight dead shock plate. Of course, every door in only shock board paper plus a sound-absorbing cotton, better, taking into account the material

thickness and space issues interior door panels, each car may be appropriate or without sound-absorbing cotton. Trunk and rear hub in the dissemination of low-frequency noise, but also increase the noise resonate degree, for which you

need to use only shock material, on this basis, and then paste the sound-absorbing cotton. It requires a total of eight dead and eight boards shock absorbing cotton.

济南汽车隔音http://www.sdcarmusic.com/提醒地盘以低频路噪音为主，因此，需要对付低频音段的隔音材料。同样，在使用止震板的基础上加隔音材料，共需9张止震板和9张隔音材料。
Jinan car sound reminds sites mainly low frequency road noise, therefore, we need to deal with the low frequency sound insulation materials segments. Similarly, the use of only shock board insulation material on the basis of increase,

totaling nine stop vibrating board and nine soundproofing material.
