济南汽车音响改装http://www.sdcarmusic.com/介绍目前国内流行的汽车车厢隔音技术汽车室内消音降噪工程，都是对这几个噪声源进行防治，以达到隔绝噪声进入车厢的目的。一台中高档轿车经过隔音施工后，其行驶噪声平均能降低6--7分贝。

1、济南汽车音响改装在引擎盖粘贴引擎盖覆膜，吸收引擎运转噪音；在车厢内加装降震消音贴膜及吸音王复合材料，缓解底盘件在高速行驶时引起的共鸣，减少由于轮胎转动所产生的路面噪音传递。
Ji'nan car audio conversion in the engine cover hood film paste, absorb the engine running noise; the installation of seismic reduction silencing film and sound-absorbing Wang composite in the compartment, alleviate the chassis parts caused at high speeds due to resonance, reduce road noise generated by the rotation of the transfer of tire.

2、济南汽车音响改装在车门饰板内贴上专用隔音王贴膜，降低行车时车门钣金件因较薄而产生的共振，减少车门饰板的松脱，降低由于金属疲劳及车身扭动时产生的杂音。
Ji'nan car audio conversion in the door trim panel is pasted in the special noise Wang film, reduce driving door sheet metal parts due to thinner resonance, reduce the door trim panel loose, reduce due to metal fatigue and body twisting murmur.

3、济南汽车音响改装采用密封条，强化Ａ、Ｂ、Ｃ柱密封性，补强后座侧板，提高车身的结构性，有效降低噪音；在车门饰件上贴中频吸音王，加装车门隔音条以加强密封性，减小共鸣声及降低汽车高速行驶的风噪声。
Ji'nan car audio with sealing strip, enhanced A, B, C column sealing, reinforcing the backseat plate, improve the body structure, effectively reduce the noise; post intermediate frequency sound-absorbing the king in the door trim, the installation of door sound insulation strip to enhance sealing, reduce resonance sound and reduce the noise of high speed automobile.

4、济南汽车音响改装http://www.sdcarmusic.com/在前后轮叶子板处喷涂喷立静隔音材料，减少行驶时避震器传入的异音，抑制轮胎与路面、钣金件所产生的撞击杂音；在车厢内顶粘上一层高性能顶级隔音王，有效阻隔太阳酷晒，防止车厢温度直线上升，减少车顶钢板震动的共鸣声。
Ji'nan car audio conversion spray sprayed on leaves at the front and rear wheel plate vertical static sound insulation materials, reduce the abnormal sound when driving shock absorber incoming, inhibition of the tire and the road surface, sheet metal impact arising from the noise; in the interior roof top stick on a high performance noise Wang, effectively blocking the sun and cool air, prevent the interior temperature rise in a straight line the roof plate, reduce the resonance vibration.
