What Causes Unpleasant Car Door Closing Sounds?

[StKatherine]

The rattling sound of metal sheets can severely disrupt the desired dull thud of a car door closing, hence damping materials are used to improve car door closing sounds. Methods to enhance door closing sounds are as follows: Applying vibration damping sheets and sound insulation cotton: Perform sound insulation on all four doors by attaching vibration damping sheets and sound insulation cotton to the door panels, which will improve the door closing sound. Inserting O-rings into the wiper strips: Some car door wiper strips along the lower edge of the window glass may be loose. When the window is halfway down and the door is closed, the glass may shake significantly, causing a loose sensation in the door closing sound. Inserting an appropriately sized O-ring into the wiper strip can make the strip fit tighter against the glass, reducing glass shaking during door closing and effectively improving the sound.
