Soundproofing strategy:
Why do cars need to be soundproof?
Everyone likes a quiet environment. The structure of a car from tens of thousands to millions of dollars is similar, so there is no need to introduce a specific model separately. Of course, the more dilapidated and more economical cars are, the better the effect, because Contrast is large. When the car is not in motion, it comes from the engine, exhaust pipe and external noise. When driving at high speed, the noise mainly comes from wind noise and tire noise.
Why use sound insulation ?
1. Prevent the heat of the engine from being transmitted to the hood, thereby protecting the paint surface of the hood,
2. The function is to absorb the noise transmitted from the engine to the outside of the car. The sound-absorbing mat on the front side of the console (i.e. the firewall) absorbs the noise transmitted from the engine to the car. Your car should have sound-absorbing mat on the firewall, which is the standard Yes, and only high-end cars have hood insulation mat .
[Sound insulation] The automobile sound insulation project can effectively eliminate and block the engine noise, vibration, resonance of the body door, friction sound generated by the road surface and air resistance when driving, giving you a quiet driving space and greatly improving driving Comfort.
[Strengthen the body] The non-critical parts of the body hood, door, rear compartment, roof, and fenders are relatively weak. After the installation of sound insulation materials, the body is stronger and the passive safety factor is improved in the event of a collision.
[Optimizing the sound effect] The sound, especially the subwoofer installed in the rear, will cause the trunk to vibrate and the sound effect will be reduced. This is because the structure of the car cannot withstand the impact of the super bass and emits "squeaks". "Squeak" sound. After the sound insulation construction, the resonance of the metal of the body is eliminated, and at the same time it has a good sound absorption effect, and the sound can be felt more clear, thick and surging.
【Construction Principles】
1. When sticking sound-proof mat to the car body, please check and tighten the screws that are exposed on the car body, especially the screws covered by the sound-proof mat . Some screws cannot be covered by sound-proof mat , such as the fixing screws of the car door handle, the purpose is to reduce the trouble of replacing these wearing parts in the future.
2. The construction quality of the sound insulation board directly affects the overall noise reduction effect after the construction of the vehicle. The principle of sticking the sound insulation mat is to stick the material tightly and firmly to the car body. As for the sticking area, the smaller the sticking area The greater the effect, the better, but it is not so important compared to the quality of the paste. After all, it is difficult to construct in some places, and it is impossible to paste the car body 100% under normal conditions.
3. Be sure to scrub the place to be pasted before sticking the sound insulation mat .
4. The screws and buckles removed during the disassembly process must be pasted near the disassembly location with transparent glue! Don't believe how strong your memory is.
5. It is impossible to have an auditory effect if only one door is made, and the construction requirements are complete.
6. Do not abandon all the leftover materials that are cut during the construction process, and can be pasted in some hidden places
