1、进行济南汽车隔音http://www.sdcarmusic.com/首先需要分析汽车噪音来源，包括车辆本身发出的机械噪音、轮胎与地面磨擦的路噪、高速行驶产生的风噪及来自外部各方的混合噪音。
Jinan car noise were first need to analyze the vehicle noise sources, including mechanical noise emitted by the vehicle itself, the friction between the tires and the road noise, wind noise at high speeds and mixing noise generated from external parties.

2、系统的济南汽车隔音http://www.sdcarmusic.com/工程通过减振、降噪、密封三个步骤来完成。车门、后备箱、车底盘、引擎盖和车顶都是容易产生空气摩擦噪音的地方，而且绝大部分的噪音又通过汽车的悬挂系统、底盘、后备箱、车门而传入车内的，所以最起码的隔音工程不能忽略车门和尾箱。
Jinan car sound system works by vibration, noise, sealing three steps to complete. Doors, trunk, car chassis, hood and roof are prone to air friction noise place, and most of the noise but also through the car's suspension system,chassis, trunk, doors and passed the car, so minimum noise project can not ignore the doors and trunk.

3、对于发动机的噪音，如果发动机本身平稳性能和静音性能不优秀，又不需要汽车发烧友渴望的加速轰隆声，那建议在引擎盖下贴一层覆膜，可吸收和消耗大量发动机的噪音，同时可以抑制引擎盖的振动和阻隔来自发动机的热量，有效率达97%，同时保护车漆表面不会因长期受高温而损伤。在冬季或在寒冷地区，这层薄膜还可以起到保温作用以保护引擎仓内机件不至于冻裂。
For engine noise, if the engine itself is smooth and quiet performance performance is not good, they do not need a car enthusiast eager to accelerate the thunder, it is recommended under the hood attached to a layer of film, can absorb

and consume a lot of engine noise, and can vibration suppression hood and blocking the heat from the engine, the effective rate of 97%, while the long-term protection of the paint surface will not be damaged by high temperatures. In the winter or in cold regions, this layer of insulation can also play a role in the film in order to protect the engine compartment parts not cracking.
