Is Installing Engine Soundproofing Cotton Effective?

[DelCalvin]

Adding soundproofing cotton to a car has some effect, but it is unlikely to significantly impact the noise level inside the vehicle, as there are multiple sources of noise, and soundproofing cotton alone cannot bring about substantial improvements. Waterproof Performance, Preventing Metal Corrosion: After soundproofing the doors, the soundproofing cotton is directly adhered to the door panels. Utilizing the excellent waterproof performance of the soundproofing cotton effectively prevents moisture from coming into contact with the door metal, thus providing rust-proof benefits. Effectively Alleviating Metal Fatigue in the Chassis: Metal fatigue occurs due to the uneven internal structure of the metal, leading to an imbalance in stress distribution, with certain areas becoming stress concentration zones. Additionally, there are many microscopic cracks in the internal defects of the metal. Under continuous force, these cracks expand, reducing the portion of the material capable of transmitting stress until the remaining part can no longer bear the load, resulting in complete failure of the metal component.
