What Are the Causes of Loud Noise in Cars at High Speeds?

[VanMichael]

Loud noise in cars at high speeds is caused by factors such as engine noise, tire noise, and wind noise. You can try soundproofing and noise reduction treatments for the entire vehicle, paying attention to selecting sound-absorbing materials with high fire resistance and heat resistance levels and lightweight properties. Below is relevant information about car noise: 1. Wind noise: The level of noise is related to the shape of the car body, which is influenced by design and does not change suddenly. If the wind noise of a car suddenly increases, it is mostly due to local deformation of the car body or significant damage. 2. Tire noise: The level of tire noise is most directly affected by speed, load, and tire tread patterns. 70% of tire noise in passenger cars comes from the design of the tread patterns. When tire noise is loud, the first step is to ensure that the tire pressure is within the appropriate range, the tires are not damaged or excessively worn, and the vehicle is not significantly overloaded.
