How to Improve Interior Noise in a Car?

[MacPatrick]

Here are specific methods to improve interior noise in a car: 1. Place soundproofing materials under the floor mats. Tire noise can enter the cabin through the chassis, and placing soundproofing materials beneath the floor mats can reduce this noise. Choose thick materials and ensure they fit snugly with the mats. 2. Add soundproofing foam behind the rear seat backrest and under the trunk mat. This effectively blocks external noise and reduces rear tire noise. 3. Install soundproofing strips on door panel joints to minimize wind noise and directly enhance audio quality. For gaps caused by aging or external impacts, apply some sound-absorbing foam to the mismatched areas. 4. Use appropriate gasoline and maintain the engine properly. Add suitable engine soundproofing materials under the hood, such as firewall insulation, to reduce engine noise.
