You know we mainly rely on vehicle noise in the engine compartment and door and other parts installed insulation cotton or insulation foam material to noise, because some resonance frequency will produce noise, so in the door, the chassis position will also install some parts of the car is reduced to prevent the resonance of materials, but in a recent piece of advertising in the article to see a new term, called the car sound insulation sealing strip.

I think it fits my judgment, the propagation of sound all middle school is taught, by the media, regardless of air, liquid, solid and we all can spread, the noise of the car is mainly from several aspects, pavement and tire vibration tire noise, engine and transmission of the functioning of the front cabin the sound of wind noise at high speeds.
If you want to have a good sound insulation, it is necessary to block the transmission path of these parts. For example, make a sound insulation layer between engine room and cockpit, make a sound insulation on the chassis, make a sound insulation layer in the four door. The sound insulation layer is almost the entire surface, and has a certain thickness of soft sound insulation material. The sound insulation material around the large circle around the cockpit is completely wrapped up, so as to effectively reduce the introduction of all kinds of noise. And that little rubber strip treatment has a slight effect on the wind noise of a part of the body connected to the joints, and the rest will not be in the slightest noise. The noise will still enter the cab through the door and chassis.
