[Construction model] Porsche Cayenne
[Construction material] Damping pad2.5mm / Polyurethane sound absorbing blanket 15mm
[Construction site] four-door Triple sound insulation
[Construction effect] Enhance sheet metal strength / Reduced resonance / Improve door tightness / Improve the audio quality of the original car / Absorb door panel cavity noise / Reduce the impact of wind noise and road noise
As can be seen from the picture, the original car door adopts plastic parts as the sealing layer, the tightness is weak, and the wind noise during the driving process is easy to enter from the gap, affecting the driving comfort and the original car audio quality. The inner layer of the original door sheet metal has only 2 small damping sheets, which can be improved by adding vibration damping materials to obtain better sound insulation.
The first layer is constructed with a 2mm vibration absorbing pad, which effectively strengthens the strength of the door sheet metal, reduces resonance and reduces noise caused by vibration.
The second layer adopts 2mm vibration absorbing pad for sealing and damping treatment, blocking the intrusion of wind noise, and forming a closed box to greatly improve the sound quality of the original car.
The interior trim of the original car door is low-gram sound-absorbing cotton, and the sound-absorbing effect is relatively weak. Replace it with a polyurethane sound absorption blanket 15mm, which can improve the sound absorption effect, absorb excess cavity noise, and reduce the impact of wind noise on the owner.
