BYD, car door soundproofing in North District

BYD, car door soundproofing in North District.
Car door soundproofing protects against road noise, neighboring cars, aerodynamic noise when driving at high speeds, prevents air blowing caused by door trim, and improves the acoustics of the car music system. To soundproof the door, it must be disassembled, and the standard soundproofing must be removed. Then the treated surfaces are cleaned and degreased. First, the inner surface of the door is pasted over with vibration-absorbing material and noise and heat-insulating material. Then the access holes are closed, the additional cover is applied to the door and the kicking plate is reinforced with materials.
