The owner of this Lexus RX270 has not done any sound insulation treatment on his car before, and he is not particularly concerned about this knowledge. Later, when I participated in a car club, I talked about the problem of car noise, and I learned that many friends in the car club had done sound insulation treatment, which made the car owner a little excited, so the car owner came to Wuxi Xiangxing to have his car repaired. Soundproofing.
Lexus RX270 sound insulation upgrade
Because he did not have any modification experience, the owner decided to start with wind noise this time and see the effect before making further decisions. According to the car owner's sound insulation needs, the technician used Jaws sound insulation material to perform targeted sound insulation treatment on the car's door panels and door panel interiors.
Construction location and material selection
Door panel: Black gold shock-absorbing glue + Golden Shark JS300
Door panel interior: Silver Shark cotton
After disassembling the car's door panel interior, you can see that the original door panel interior only has a simple layer of plastic film. It is difficult to achieve good sound insulation effect. Technicians removed the poor quality sound insulation material from the original car. Inside the cabin, black gold shock-absorbing glue is used to dampen door panels to reduce the generation of low-frequency resonance noise. On the outside of the car, Gold Shark JS300 is used to provide anti-vibration treatment to the door panels. Two layers of anti-vibration materials, inside and outside, allow the door panels to form a sealed box. On this basis, technicians also use Silver Shark cotton to perform sound-absorbing treatment on the interior of the door panels. , through multi-layer construction, effectively prevent the introduction of wind noise.
The original door panel has no sound insulation treatment
Use King Shark JS300 for anti-vibration treatment on the outer layer of the door panel

And the car The rear door panel also uses black gold shock-absorbing glue + Golden Shark JS300 for double-layer anti-vibration treatment to reduce the introduction of noise, so that rear passengers can also enjoy a quiet and comfortable riding environment.
The back door panel only has a simple layer of plastic film
Use black gold shock-absorbing glue to perform anti-vibration treatment on the inner layer of the door panel
Use Golden Shark JS300 to perform anti-vibration treatment on the outer layer of the rear door panel

[Comment on modification effect] After the upgrade was completed, the car owner did a road test and could clearly feel that the wind noise around the door panels had dropped a lot. The car owner was very surprised by this and said on the spot that he must do other parts of the car next time. More comprehensive sound insulation treatment.
