What are the methods for reducing car noise?

You can install some high-end sound-absorbing foam and other materials on the engine hood, which can not only effectively suppress the vibration caused by the hood but also more effectively absorb a large amount of noise, with very noticeable results. Tire noise: Tire noise is generated when the vehicle is driving at high speed and is caused by the friction between the tires and the road surface. Generally speaking, the faster the speed, the greater the vehicle load, and the worse the road conditions, the louder the tire noise will be. Vibration is one of the main sources of tire noise. You can install vibration damping plates along with sound-absorbing pads to reduce the occurrence of vibrations. In addition, you can also try replacing tires with better noise reduction performance, also known as silent tires, which are optimized by tire manufacturers to change the tread design to reduce noise.
