What are the reasons for the loud noise in BMW X3?
1 Answers
The following are the reasons for the loud noise in BMW X3: 1. Poor door sound insulation: The first step is the door sound insulation treatment, which mainly aims to reduce the wind noise of BMW X3. Remove the door panel accessories to check the original door's sound insulation treatment. There is a layer of damping plate, which is thicker than that of other models; however, the sound insulation materials used in the original car are relatively ordinary, and the sound insulation effect still needs improvement. 2. Poor original sound insulation materials of the car body: Choose to paste automotive sound insulation materials with better damping effects, otherwise the noise will be very loud. It effectively enhances the solidity of the metal sheet, avoids the resonance phenomenon of the metal sheet, and effectively reduces wind noise intrusion. After double-layer sound insulation treatment of the front and rear doors, the wind noise will be significantly reduced. 2. Poor cabin floor sound insulation: Next is the cabin floor sound insulation, mainly to reduce road noise and chassis resonance noise. Remove the seats, carpets, and other accessories. This is the original chassis structure of BMW X3. The original car's sound insulation treatment is still relatively minimal.
