Is Trunk Soundproofing Effective?
1 Answers
Trunk soundproofing is effective. Installing soundproofing cotton in the trunk can absorb some of the energy produced by noise and convert it into heat, which then dissipates. Applying soundproofing and vibration-damping panels to the trunk can effectively reduce vibrations during driving. Adding an additional layer of sound-absorbing cotton can effectively block exhaust pipe noise, as well as tire and road noise during driving. Furthermore, performing the same soundproofing treatment on the wheel arches inside the trunk can better isolate tire noise from entering the cabin. The soundproofing materials used should meet the following standards as much as possible: Lightweight materials: Lightweight is a major trend in the entire automotive manufacturing industry. Lightweight materials, after installation, will not significantly increase the vehicle's weight, which could otherwise lead to higher fuel consumption. They should also have good soundproofing and sound-absorbing performance across a wide frequency range, with long-term stability and reliability. Sufficient strength: The materials should be resistant to damage during installation and use, not prone to aging, have good weather resistance, and a long service life. They should also be clean in appearance and free from pollution.
