Is Car Soundproofing Modification Effective?
3 Answers
Car soundproofing modification is effective. Because soundproofing modifications will significantly alter engine noise, road noise, tire noise, wind noise, and structural noise of the vehicle body, the soundproofing effect after modification is very noticeable. Below is relevant information about car soundproofing devices: Definition: Car soundproofing involves detailed treatment of engine noise, resonance from tires and road vibrations, and friction noises caused by gaps or aging components inside the cabin, based on the vehicle's performance, corresponding road conditions, and usage conditions, to enhance the comfort of the car ride. Main Functions: Reduce interior noise; Improve audio effects; Lower interior temperature; Delay paint film aging.
The soundproofing upgrade made a real difference. My five-year-old car used to sound like a tractor on the highway. After adding double-layer soundproofing foam to all four doors, applying vibration damping sheets to the wheel arches, and most surprisingly, installing heat insulation under the hood, the results are remarkable. At 80 km/h cruising speed, tire noise is reduced by half. I can now hear song lyrics clearly without cranking up the volume, and my wife can make phone calls from the passenger seat without shouting. Although it cost over 2,000 yuan, my two-hour daily commute has become much more comfortable, and my child can sleep peacefully in the back seat during long road trips. I recommend having it done by professionals, as DIY installations might leave gaps that compromise the effect.
As a business owner who frequently drives, I find the soundproofing modifications well worth the cost. Previously, clients would often frown and complain about the noise in my car. Now, after full-vehicle soundproofing, applying rubber coating to the chassis, and adding sound-absorbing cotton in the trunk, the loud bangs over speed bumps have turned into muffled thuds. Wind noise on the highway has significantly reduced, and the most unexpected improvement was in the audio quality. However, there are three points to note: avoid using low-quality materials that may emit odors, do not randomly apply soundproofing around the sunroof as it may affect drainage, and be aware that the added weight from modifications might slightly increase fuel consumption. Overall, the improvements are quite noticeable, especially for those who frequently drive on highways.
