There are four solutions to car noise: 1. Engine noise: The vehicle engine is a source of noise, and its noise varies with engine speed. Solution: Install high-grade sound-absorbing foam materials on the engine cover, which can not only suppress vibrations 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 during high-speed driving. The level of tire noise depends on road and vehicle conditions—the worse the road conditions, the greater the tire noise. Additionally, there is a significant difference between the tire noise produced on asphalt roads and concrete roads. Solution: Tire noise is a type of structural noise, primarily caused by vibrations. The most reasonable solution is vibration control. Adding damping plates along with sound-absorbing pads can effectively reduce road and tire noise. 3. Wind noise: Wind noise occurs when the pressure of oncoming wind exceeds the sealing resistance of the car doors during high-speed driving, entering the cabin. The faster the driving speed, the greater the wind noise. Solution: Install or replace door sealing strips. Since sealing strips are made of rubber, they tend to 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 metal components in the body due to internal and external forces. Solution: This issue rarely occurs in new cars. Check whether the screws on body components are loose. Generally, tightening the screws or replacing the parts can resolve the problem.

Car noise is really annoying. As an experienced driver, I believe the key lies in preventive maintenance. Regularly check tire pressure—if it's too low, it can cause a humming sound, and maintaining the right pressure can reduce noise and wear. Regular oil changes for the engine are also crucial, as old oil can lead to strange noises. For example, the exhaust system—if the pipes are loose or leaking, it can produce a buzzing sound, so I check monthly for rust or looseness. Worn brake pads can also create a screeching noise, and replacing them early can prevent it. I’ve also noticed interior noises, like loose seat or door hinges—adding some lubricant can quiet them down. Developing these habits not only reduces noise but also improves comfort and safety. In the long run, it saves on repair costs and is more eco-friendly, since noise pollution is unpleasant anyway. For complex issues, I still recommend getting a professional inspection at a repair shop.

When I hear noises from the car, I usually start by identifying where they're coming from. For example, if there's steering wheel vibration or a humming sound at low speeds, it might indicate low tire pressure or wheel imbalance—then I'll find a safe spot to pull over and check the tires. If the engine makes a rattling noise during acceleration, it could be a loose or worn belt; a quick inspection under the hood can help diagnose that. Squealing sounds when braking often mean the brake pads need replacement. I recommend testing the noise under different speeds and conditions, like comparing smooth and bumpy roads. For safety, if a noise appears suddenly, don't push it—stop and find a secure location. After troubleshooting, minor issues like loose bolts can be tightened yourself, but complex problems like electrical faults should go straight to a mechanic. Delaying repairs might worsen the issue, distract the driver, or even cause accidents.

I always try to handle car noises myself. When the engine has slight abnormal sounds, changing the engine oil usually solves it. For squeaky doors, I spray some WD-40 lubricant to eliminate the noise. For loose interior parts like a shaking glove box, I temporarily fix them with tape. If the tire pressure is insufficient, I check and inflate them at home using a pressure gauge. These simple DIY methods are easy and convenient, requiring only everyday tools. However, don't tamper with core components like brakes—safety comes first. If there's an issue, it's worth spending money to have a professional mechanic fix it. Long-term neglect of noises may shorten the car's lifespan, so act early but know your limits.
