How to reduce tire noise and wind noise

Sihai network: like people walking, noise will inevitably appear in the process of car driving, generally caused by tire noise and wind noise. The car noise is very ordinary people. If the noise is still not improved after the tire noise is handled, it is necessary to consider handling the wind noise.

What is wind noise

Wind noise refers to that the pressure of the face-to-face wind in the process of high-speed driving has exceeded the sealing resistance of the door and entered the vehicle. The faster the driving speed is, the greater the wind noise is (mainly through: four door sealing clearance, including the generation and transmission of the whole sheet steel). Generate resonance noise, the car body itself is like a box, and the sound itself has the nature of refraction and overlap. When the sound is introduced into the car, if there is no sound absorption and sound insulation material to absorb and block, the noise will continue to refract and overlap, forming resonance sound.

How to reduce wind noise

Wind noise is caused by the wind pressure exceeding the resistance of the door seal, so strengthening the resistance of the seal is the most direct and fundamental solution. The door seal and inner seal can solve this problem well.

How to deal with the wind noise of the car

What do you need to pay attention to when choosing sealing strips?

1. Elasticity of sealing strip

Strong elasticity and flexibility enhance the sealing effect, and increase the service life of the sealing strip.

2, 3M back glue

The sealing strips produced by regular manufacturers are made of 3M back glue, which has strong adhesiveness and can be firmly pasted without any adhesive aid.

3. Waterproof tank

High quality sealing strips are equipped with waterproof grooves to increase the waterproof performance.

4, smell

The sealing strip produced by regular rubber is glossy on the surface, without obvious peculiar smell, non-toxic and harmless. If there is a clear smell of the car owners should be careful, after all, now has been emphasizing the air quality problems in the car.
