Is Car Chassis Soundproofing Effective?
2 Answers
Car chassis soundproofing is effective, but the effect is not very significant. Benefits of installing chassis soundproofing: Car chassis soundproofing primarily targets road noise generated by the friction between tires and the ground, which can significantly reduce such noise and greatly enhance driving safety for the owner. Applying vibration-damping strips and soundproofing cotton to the chassis will effectively absorb any vibrations and block heat. Methods for chassis soundproofing: Chassis soundproofing modifications can involve applying a layer of chassis armor on the exterior. Chassis armor is an elastic sealing material that can provide noise reduction from the outside. For interior chassis soundproofing materials, smooth-faced sound-absorbing cotton or 10mm textured sound-absorbing cotton can be chosen, combined with aluminum foil soundproofing and vibration-damping panels. Next, measure the noise levels in various parts of the car, then proceed to remove the interior trim carefully—avoid using excessive force to prevent damage to the trim and paint layers. After that, clean the chassis thoroughly, paying attention to the handling of any adhesives to avoid scratching the work surface or paint layers. Avoid using corrosive solvents.
As a veteran driver with twenty years of experience in family cars, I firmly believe that soundproofing the chassis makes a noticeable difference. For example, after the upgrade, the tire roar on highways is significantly reduced. Previously, listening to music was a struggle, but now the cabin is as quiet as a study, greatly enhancing comfort. I opted for professional materials like soundproofing foam or insulation blocks and had them installed by specialists to avoid waterproofing issues. However, material quality is crucial—cheap alternatives may degrade and lose effectiveness in just two or three years. I advise ensuring a sufficient budget before attempting this, as decent packages including installation start at several thousand yuan. Overall, it helps reduce fatigue during long-distance driving, but the effect varies by vehicle type, with sedans showing more improvement than SUVs.
