four-door soundproofing
Why upgrade the four-door soundproofing? On the one hand, it can strengthen the strength of the door sheet metal, in addition, it can inhibit the vibration of the sheet metal and improve the speaker effect, basically upgrade the car audio owners, will choose to upgrade the door sound insulation.
The inner sheet metal is constructed with 2.5mm vibration damping pad, which can effectively strengthen sheet metal strength and restrain sheet metal vibration;The 2.5mm vibration damping pad is used to seal the holes of the sheet metal on the second layer to suppress the vibration of the sheet metal, improve the sealing of the door, form a closed door speaker, and improve the sound quality of the original car.
The interior trim of the door adopts polyurethane sound absorbing blanket 15mm for sound absorbing treatment, absorbing the resonating noise of the door cavity and reducing the transmission of wind noise to the door.
chassis and trunk Soundproof
The owner of the SUV construction, generally choose the chassis and the tailbox construction together, the sheet metal using vibration damping material to suppress the sheet metal vibration, the second layer using sound insulation pad, noise barrier, improve the comfort of the vehicle.
The first layer of sheet metal uses a 2.5mm vibration damping pad to suppress the vibration of the chassis sheet metal and reduce the noise caused by vibration. The second layer is above the sheet metal, and the construction is carried out using a sound insulation pad of 6mm to block the transmission of noise to the cockpit, reduce the impact of low-frequency noise, and block the transfer of heat.
Wheel Soundproof
The formation of tire noise is mainly determined by the tire and the road surface. As the main channel for tire noise, road noise, engine noise and exhaust pipe noise to be transmitted to the cab, these noises are rotated and reflected and amplified in the cavity formed on the inside of the wheel arc, and transmitted to the car through the vibration, holes and door gaps, which seriously affect the driving comfort.
There is basically no vibration reduction, sound insulation and sound absorption materials on the original car leaf board.
After construction, the first layer of the wheel uses 2.5mm vibration damping pad to strengthen the sheet metal strength and suppress the sheet metal vibration. Then use a sound insulation pad 6mm above to block the transmission of road noise.
