Are soundproof strips really effective?
2 Answers
Automotive soundproof sealing strips are not very effective. Functions of automotive sealing strips: Automotive sealing strips serve to fill various gaps and seams between vehicle body components. They provide functions such as vibration reduction, waterproofing, dustproofing, sound insulation, and decoration, enhancing driving comfort and protecting the vehicle body. Disadvantages of sealing strips: The soundproofing effect is not significant. After installing door sealing strips, they can easily become clogged, leading to poor door drainage. This may result in damage to the door window lift motor or rust on the door panel. After installation, the sealing strips can affect the overall appearance, making the doors more noticeable. If the sealing strips fall off, adhesive residue may remain on the car paint, which is difficult to remove.
I think the soundproofing strips are indeed effective, and the results are quite noticeable. I've tested them several times on my car that's over a decade old. I installed some on the door edges and hood, and found that wind noise was significantly reduced, especially making highway driving much quieter. However, the effectiveness depends on what materials you buy and whether they're installed correctly. Cheap soundproofing strips might only offer minimal improvement, while premium ones like high-quality rubber work better as they can seal gaps to block noise intrusion. Older cars show more obvious results because worn-out factory seals tend to leak sound. I'd recommend choosing reputable brands rather than going for the cheapest option. During installation, clean the surfaces thoroughly and ensure tight adhesion, otherwise they may peel off in harsh weather, rendering them useless. Overall, the cabin feels much more comfortable after installation, particularly for long trips where noise fatigue is reduced - definitely worth trying. It's an easy DIY project anyway, costing just around a hundred bucks to complete.
