【Chevrolet Maribor Great White Shark Sound Insulation】The sound insulation effect of the original car is quite OK, but the owner's requirements for tranquility are higher, so the whole car has been upgraded for the car. The two layers inside and outside the door are covered with black gold shock absorbing adhesive, increasing the thickness of sheet metal, reducing resonance noise, and forming a sealing environment to block the transmission of road noise and wind noise to the carriage, effectively sound insulation. The trunk and inner fender position are first paved with a layer of Golden Shark JS300, do vibration damping and sound insulation treatment, and then add a layer of sound insulation mat to strengthen the sound insulation effect. The third layer is silver shark cotton and high elastic cotton, which can effectively absorb the remaining noise, more thoroughly block the tire noise and low-frequency resonance noise and roar noise of the tail box. The arc position of the wheel is to strengthen the sound insulation treatment, the combination of golden shark JS300 and the sound insulation mat, do a comprehensive vibration stop treatment, reduce the low-frequency resonance noise, but also can block a part of the tire noise and road noise; High elastic cotton and silver shark cotton were then used to absorb the sound of the arc part of the wheel, which reduced the noise propagation. The combination of noise-reducing materials of different materials makes the sound insulation effect more outstanding and the effect is naturally excellent.
