Is Full Soundproofing Effective for the Accord?
2 Answers
Full soundproofing for the Accord is effective and yields noticeable results, but the potential consequences after the soundproofing should also be considered. Noise test results for the Accord: The Honda Accord's noise levels measure 38.5 decibels at idle, 59.3 decibels at 60 km/h, 60.9 decibels at 80 km/h, and 64.1 decibels at 120 km/h. Users seeking better soundproofing can opt for full-vehicle soundproofing, including door soundproofing, chassis soundproofing, trunk soundproofing, and engine compartment soundproofing. Negative consequences after soundproofing: Most modern car interior components are snap-fit, making them prone to loosening after disassembly and reassembly. If installation does not meet factory standards, dust leakage may occur. Poor-quality soundproofing materials can emit toxic fumes in high-temperature areas, affecting human health.
I had soundproofing done on my Accord last year, and overall it does make a noticeable difference, but don’t expect miracles. Wind noise at high speeds is reduced by 30-40%, and tire noise on rough roads isn’t as piercing anymore. However, you can still hear the engine’s humming during acceleration—pairing it with quiet tires would help further. The most effective areas for soundproofing are the chassis and wheel arches, while the roof and door panels show less improvement. Make sure to supervise the installation to prevent the shop from skipping sealant spots, and the thickness of the soundproofing material matters too—too thick can interfere with door closing. If your budget allows, it’s worth doing; daily commutes are much more comfortable for your ears. That said, complete silence isn’t achievable, given the car’s inherent soundproofing structure.
