How to Soundproof a Sail 3
2 Answers
Here are the methods for soundproofing a Sail 3: 1. Use GT Vibration Damping King and GT Sound Absorption Cotton for double-layer soundproofing on the firewall, which can reduce the roar of the engine and low-frequency noise caused by engine vibration. Due to the numerous involved circuits, soundproofing the firewall is relatively complex and time-consuming. 2. Use GT Vibration Damping King and GT Sound Absorption Cotton for double-layer soundproofing in the trunk, effectively reducing the cavity resonance noise from the spare tire well. The sheet metal area of the chassis and trunk is large, but soundproofing is relatively simple. After treatment, it can reduce resonance noise and enhance the rigidity of the sheet metal. 3. Use GT soundproofing materials for soundproofing treatment on the engine hood and trunk lid, significantly reducing resonance noise generated during driving. Perform soundproofing treatment on the wheel hubs and the wheel arches and fenders outside the cabin to cut off the transmission path of tire noise.
For owners like myself driving a Sail 3, soundproofing can start with simple steps. When I did it, I removed the door panels, cleaned them thoroughly, and then applied sound-absorbing foam—the thick kind that blocks noise, which is very affordable on Taobao. Next, I laid two layers of soundproofing foam on the floor and in the trunk to reduce road noise. Adding heat insulation foam under the hood also helps dampen engine noise. The whole process is a bit time-consuming, but if you're handy, you can do it yourself with just a screwdriver and scissors. Avoid using poor-quality materials to prevent unpleasant odors. After completion, the cabin is much quieter, with wind noise on the highway reduced by half. Now, when I drive and listen to music, there's no more buzzing.
