It has always been very admirable for those engineers who are doing car modifications. I really think they are very powerful. For car modification, in fact, more is the modification of the car interior. Car noise conversion believe that many friends have heard that for those who pursue a comfortable driving environment, noise is a good choice to effectively reduce the car noise. However, there are still many friends who have some misunderstandings about the car's sound insulation modification. First of all, let us introduce the role of car noise: 1. Sound insulation: Car noise engineering can effectively eliminate and block engine noise, vibration, resonance of body doors, friction noise generated during driving and road surfaces, and air resistance, and create a quiet driving space for you. Improve the comfort of driving. 2. Insulation: The soundproofing works not only can be soundproof, but also can effectively block the high temperature generated by engine work and improve the air-conditioning cooling, especially in the summer to make you feel cool. 3. Strengthen the body: For the non-critical parts of car body covers, doors, back-up cabins, roofs, and fenders, the gold-plated iron sheet is relatively weak, and after the sound insulation material is installed, the body will be more sturdy. In the event of a collision, the safety factor is improved. 4. Optimize sound effects: The sound, especially the subwoofer installed at the rear, will cause the trunk to vibrate slightly and the sound effect will be reduced. This is because the shock absorber is not properly constructed and the structure of the car cannot withstand the impact of super bass. "Oh" sound. After the construction of the sound insulation, the resonance of the body metal is eliminated, and at the same time there is a good sound-absorbing effect, and the sound can be perceived as more clear, thick and sturdy. Now let's talk about car noise conversion. Everyone knows that the car shell is made by splicing many pieces of sheet metal, so there will certainly be gaps in the process of splicing. First, because there is no possibility of complete integration, the second is to ensure that air flows into the car and the chassis of the vehicle is preserved. There is a gap. Engine noise, tire noise, and air noise will be introduced into the car from the gap, and the noise of the body structure is caused by the vibration of various parts of the vehicle caused by the vehicle during driving, so it is more direct to the vehicle. In order to reduce the impact of these four kinds of noise on the interior of the vehicle as much as possible, the noise in the interior of the vehicle is reduced from the four aspects of sound absorption, sound insulation, shock absorption, and sealing. That is, a sound insulation project is performed for the entire vehicle. As for the selection of sound insulation materials, most of them are made of high-quality butyl rubber, and the surface is compounded with black shock-absorbing aluminum foil, and the surface of aluminum foil is coated with sound-absorbing paint. It has strong shock absorption and sound insulation effect, high anti-aging strength, good viscosity, long service life, and environmental protection and tastelessness.
