Is Soundproofing Car Doors Effective?

[DaisyLynn]

Soundproofing car doors is effective. The principle of soundproofing is to increase the damping coefficient when the door panel vibrates. Steps for soundproofing car doors: 1. Drive the car to a safe location, engage the handbrake, and turn off the engine; 2. Remove the interior trim in the order of outside first, then inside, exposing the inner part of the door; 3. Thoroughly clean the inner part of the door with a cleaning agent; 4. Mold the soundproofing material inside the door and cut it to the appropriate size with scissors; 5. Remove the protective kraft paper from the back of the soundproofing material and stick it to the inner part of the door; 6. Reinstall the interior trim from inside to outside as it was originally, ensuring all components are reassembled exactly as before, with screws and clips tightened and secured.
