Does the Accord Need Soundproofing?

[JaylaLynn]

The Accord needs soundproofing, which can isolate external noise, protect physical and mental health, enhance the vehicle's grade, improve riding comfort, absorb and reduce cabin noise caused by vibrations, enhance riding comfort, eliminate travel fatigue, and reduce the harm of noise to the human body. The Accord is a model under Honda, with body dimensions of 4893mm in length, 1862mm in width, and 1449mm in height, and a wheelbase of 2830mm. In terms of appearance, the Accord adopts the LED high-mounted brake light commonly used in luxury models and the elegant triangular combination taillights, which are simple and lively, creating an impression of elegance and stability together with the unique wide license plate panel; the rear styling achieves a more harmonious echo with the front, making the overall vehicle image more prominent.

Last time I helped my friend soundproof his Accord, it was quite a hassle, but the results were immediate. At highway speeds, the tire noise was muffled like under a blanket, and the engine sound was significantly reduced. The key areas to address are the four doors, wheel arches, and trunk—you have to remove the interior panels and cover them with damping sheets and sound-absorbing cotton, and the sealing strips also need to be replaced with thicker ones. That said, I have to admit the Accord's stock sound insulation is average for its class, and it’s actually sufficient if you mainly drive in the city. But if you frequently take long trips and are sensitive to noise, spending three to four thousand on professional soundproofing is worth it—just make sure to find a reputable shop and avoid cheap, low-quality materials.

I've driven an Accord for five years and feel that noise insulation is a matter of personal tolerance. The stock setup is decent at low speeds, but the wheel arch rumble on rough roads can be quite annoying. A simple solution is to spend a few hundred bucks on four quiet tires, like Michelin Primacy, which can immediately reduce noise by 30%. Adding soundproofing mats to the trunk can also dampen resonance, a DIY job that takes about an hour. If it's still too loud, focus on the front wheel arches and underbody armor—rubber materials work best. Actually, adding soundproofing mats when upgrading the audio system is particularly cost-effective, killing two birds with one stone. But a heads-up: full-car soundproofing can add around 40 kg to the vehicle weight, potentially increasing fuel consumption by half a liter.

Comparative testing of noise data between the Accord hybrid and gasoline versions shows the hybrid is significantly quieter at low speeds. However, once speed exceeds 80 km/h, wind noise becomes the dominant sound source. Recommendation: First check window sealing - hardened/deteriorated weatherstripping causing air leaks is common in older vehicles. Cost-effective modification: Spend 300 yuan to replace four-door seals + front wheel arch sound insulation panels can notably reduce high-frequency noise. Important note for soundproofing: Avoid blocking drainage holes - some owners reported water accumulation in door panels after DIY insulation foam installation. The factory firewall insulation is actually decent - if modification is necessary, dashboard removal is required, making labor costs exceed material expenses.

When I used to drive my kids to school, I always found the humming noise coming from the Accord's chassis annoying. Later, a mechanic taught me a DIY solution: lay two layers of sound-absorbing cotton in the spare tire compartment in the trunk and stuff egg crate foam under the rear seats. Then install soundproofing strips on all four doors—even the door-closing sound became more solid. The most effective fix was applying chassis armor coating, which is like slathering a layer of concrete under the car, making small stone impact noises almost disappear. However, the vibration noise from the AC pipes became more noticeable and required separate soundproofing sleeves. Now, on long trips, the kids sleep soundly in the back seat. The only downside is a slight rubber smell inside the car after summer sun exposure, which takes about two weeks to fully dissipate.
