How to Solve Car Noise Problems?
2 Answers
Solutions for car noise are as follows: 1. Road noise and tire noise are both structural noises, primarily caused by vibrations. The most reasonable solution is vibration reduction by installing damping plates along with sound-absorbing pads, which can effectively address road and tire noise. 2. Wind noise occurs when wind pressure exceeds the sealing resistance of the doors. Therefore, enhancing the sealing resistance is the most direct and fundamental solution. Door sealing strips and inner sealing strips can effectively resolve this issue. 3. Additionally, comprehensive treatment of the fenders, floor panels, and doors using specialized damping plates, sound-absorbing pads, and door sealing strips can improve noise reduction from three sources: vibration damping, sound absorption, and sound insulation.
The car makes a rattling noise when driving, and I've encountered this issue several times. Start with the tires: insufficient tire pressure or worn-out tread patterns can cause loud noises, especially on highways. Check the tire pressure gauge and adjust it to the proper value. Besides tire issues, an improperly closed engine hood can also produce a buzzing sound—check if the fastening screws are loose. Then, if the window seals are aged, they may whistle when wind blows; try cleaning the gaps or applying some sealant. If there's a thumping noise from the chassis, it might be due to damaged suspension components, requiring lubrication or replacement at a shop. Avoid bumpy roads when driving, and regularly wash the car to remove dirt and sand—this not only reduces noise but also improves safety. Overall, troubleshooting step by step is the simplest approach. Don't force it, as it may damage other parts.
