Methods for soundproofing car doors: 1. Remove the door interior panel and clean the door surface with a cleaning agent; 2. Cut damping material to an appropriate size and paste it inside the door, then use a glue scraper to smooth it evenly; 3. Cut sound-reflecting material to a suitable size and paste it on the inner panel, then use a glue scraper to smooth it evenly; 4. Apply sealing material around the speakers and mounting plates; 5. Reinstall the interior components from the inside out as they were originally. Car doors provide access for the driver and passengers, isolate external disturbances, and to some extent reduce side impacts, protecting the occupants.
I often help friends with soundproofing their car doors, it's like adding a little ear protection layer to the car. The first step is to remove the door panel by unscrewing the bolts with a screwdriver, being careful not to damage the clips. Once the door panel is off, peel off the factory plastic film and clean the metal surface of the door panel—grease can affect adhesion. Then, apply soundproofing material, like Dynamat aluminum foil soundproofing felt, cut to the right size, pressed firmly to avoid air bubbles. Stuff some acoustic foam into the gaps inside the door panel to absorb excess resonance noise. Finally, reinstall the door panel and test the sound when closing the door. After soundproofing, wind and tire noise are significantly reduced, improving driving comfort. Remember to wear gloves and use an anti-static mop to avoid skin scratches. Beginners should watch video tutorials first to avoid mistakes.
