How to Deal with Excessive Noise Inside the Car?
2 Answers
There are four solutions to car noise: 1. Engine noise: The vehicle engine is a source of noise, and its noise varies with the engine speed. Solution: Install some high-quality sound-absorbing foam materials on the engine cover, which can not only suppress the vibration caused by the hood but also absorb a large amount of noise, with noticeable effects. 2. Tire noise: Tire noise is generated by the friction between the tires and the road surface when the vehicle is driving at high speed. The level of tire noise depends on the road and vehicle conditions—the worse the road condition, the greater the tire noise. Additionally, there is a significant difference in tire noise between asphalt and concrete roads. Solution: Tire noise is a type of structural noise, primarily caused by vibration. The most reasonable solution is vibration control. Adding damping plates along with sound-absorbing pads can effectively address road and tire noise. 3. Wind noise: Wind noise occurs when the pressure of the oncoming wind exceeds the sealing resistance of the car doors during high-speed driving, entering the car. The faster the speed, the greater the wind noise. Solution: Install or replace the door sealing strips. Since sealing strips are rubber products, they can age over time, leading to reduced sound insulation and sealing effectiveness. 4. Body structure noise: This is mainly influenced by two factors—the vibration transmission method of the body structure and the noise generated by the metal components of the body under internal and external forces. Solution: This issue rarely occurs in new cars. Check whether the screws on the body components are loose. Generally, tightening the screws or replacing the parts can resolve the problem.
As a seasoned driver with over a decade of experience, I've encountered numerous in-car noise issues, typically stemming from tires or wind interference affecting driving comfort. The most straightforward solution is to check tire conditions—if tires are severely worn or have uneven pressure, they can produce a humming sound. I recommend switching to noise-reducing tires, like certain Michelin models, which are quite reliable. Next, inspect the door and window seals; if they're aged, they can leak air and cause wind noise. Spending a little to replace them or applying soundproofing tape can help. Adding soundproofing material under the hood is also effective, but don't overdo it to avoid affecting heat dissipation. While driving, maintain a steady speed, avoid bumpy roads, and refrain from sudden acceleration. Excessive noise isn't just annoying—it can also distract and lead to accidents. I regularly perform these checks to ensure both safety and comfort.
