[Lexus RX270 Great White Shark] Although it belongs to the ranks of luxury cars, the owner feels that the wind noise and road noise are too large, so they have made a soundproof upgrade. This time the soundproof construction is mainly the location of 4 doors. After shoveling off the plastic film and cleaning it, the technician first laid a layer of black gold shock absorbing glue inside the door panel to increase the thickness of sheet metal and reduce low-frequency resonance. The second layer is the Golden Shark JS300, which seals the door to reduce the transmission of wind noise and road noise, and forms a sound box structure, which is more conducive to the sound of the horn, and the acoustic effect of the original car is also improved. The interior of the door panel is a layer of silver shark cotton configuration, which effectively isolates the noise of the high-frequency band and prevents the door panel from resonating, and the complete 3-layer sound insulation tacit cooperation makes the car environment more quiet and comfortable.

Retrofit configuration:

Door panel: black gold shock absorbing glue + golden shark JS300

Door panel interior: Silver shark cotton
