What Causes Excessive Wind Noise in Sedans?

[SanPaul]

Excessive wind noise in cars is caused by engine operation noise, tire noise, driving wind noise, and chassis noise. Detailed reasons and solutions are as follows: Engine operation noise: You can install a sound insulation pad to block the engine noise from entering the cabin. Tire noise: Tire noise is unavoidable, but you can replace them with quieter tires if possible. Driving wind noise: Wind noise occurs when wind pressure exceeds the door's sealing resistance, allowing noise to enter the cabin. Adding sealing strips or sound insulation pads to the door frames can help. Chassis noise: The chassis serves as the vehicle's foundation, bearing weight while also being subjected to noise. During driving, the chassis interacts with air friction, and the drivetrain operates beneath the car, combined with tire noise. Applying sound insulation pads and vibration damping sheets to the bottom of the trunk can be highly effective.
