Is Fender Soundproofing Effective?

[JohnLynn]

Fender soundproofing has minimal effect, but fender liner soundproofing is effective. Below the fender, above the wheel, there is a black plastic piece called the fender liner. This component prevents mud, water, or stones kicked up by the tires from entering the engine compartment. Many high-end luxury cars have some soundproofing design in their fender liners. When driving, most of the noise comes from wind and tire noise. If the car has a high drag coefficient, wind noise will be more noticeable at high speeds. To reduce noise, you can also install door soundproofing foam, which can block most of the noise.

I believe fender sound insulation is indeed effective, primarily because tire and road noise enters the cabin through vibrations. Adding soundproofing materials like butyl rubber or acoustic foam near the wheel arches can absorb vibrations and reduce noise intensity. At the modification shop, I've seen many car owners who reported significantly reduced cabin noise after installation, especially noticeable tire noise reduction at highway speeds, making conversations and music listening more comfortable. However, the effectiveness depends on material quality and installation method: using cheap materials or DIY installation with poor adhesion may diminish results and could lead to moisture retention and rust issues. I recommend choosing high-density materials and combining them with carpet and door panel soundproofing for more comprehensive noise reduction, resulting in a more noticeable overall comfort improvement. For older vehicles with degraded factory insulation, adding fender soundproofing offers good cost-performance, effectively reducing daily driving fatigue.

Last month, I just added fender sound insulation to my car, and the difference is quite noticeable. Before, the tire noise was buzzing loudly, but now it's much quieter, especially on gravel roads where the noise has significantly reduced, allowing me to focus on listening to the radio. I used a three-layer sound insulation pad, including damping sheets and sound-absorbing cotton, and it took me half a day to install it myself. It cost a few hundred yuan, not much, but it improved the in-car atmosphere. Why is it effective? Because the wheel arch is the main entry point for noise, and once the material is applied, it blocks the transmission of vibrations. I recommend fellow car enthusiasts to give it a try, choosing high-quality moisture-proof materials and not blocking the drainage holes. With simple maintenance, the sound insulation can last for several years.

To perform fender sound insulation, first inspect the vehicle condition: the investment is worthwhile when noise is significant, typically reducing a few decibels for a more comfortable drive. Choose sound insulation pads to install inside the wheel arches to block tire noise sources; follow professional advice to avoid incorrect operations. The effect is generally positive, but don't expect to eliminate all noise.

I think the fender sound insulation is effective, significantly reducing noise and improving safety and ride comfort. With less noise, driving is less tiring and attention is more focused, enhancing safety. The added materials also cushion vibrations, with noticeable improvements especially at high speeds or during long trips. It's recommended to regularly check for any looseness to ensure the effects last.
