Is it necessary to do sound insulation for a new car?
2 Answers
It is not necessary to perform full-car sound insulation for a new car. Detailed information is as follows: 1. Improper car sound insulation modification may lead to many adverse consequences. Car sound insulation should be meticulously handled based on the vehicle's performance, corresponding road conditions, and usage conditions. 2. Adverse consequences of improper sound insulation modification: (1) Most of the current car interior parts are snap-fitted and may become loose after disassembly and reassembly. (2) If the connection parts are not installed to the original factory standards, it may lead to dust leakage. (3) Poor-quality sound insulation materials may release toxic gases when exposed to high temperatures. (4) It may leave traces of prying on certain components.
New car sound insulation does improve driving comfort, but I have to say it depends on the specific situation. When I first picked up my car, I also struggled with this issue, but later found that the factory sound insulation wasn't actually bad and was completely sufficient for daily commuting. Unless you frequently drive on highways or are particularly sensitive to engine noise, there's really no need to rush into modifications. While adding soundproofing materials can reduce tire and wind noise, removing door panels carries the risk of rattling, and if not done properly, may require reinstallation. My friend spent over 5,000 yuan on full-car sound insulation for his SUV, only to find that low-frequency resonance became more noticeable. If you really want to improve, I suggest first trying to replace four quiet tires—it's cost-effective and doesn't require altering the car's original structure.
