The resonance layer of resonant cotton often occurs when the left or right side door of Honda Accord 8 is closed. The sound manifests itself in both new and old cars. At the same time, if the trunk is open, no cotton can be heard. The reason for this is the special antivacuum valve which is intended to compensate the pressure in the passenger compartment at the time of closure. It is located in the boot side of the trunk near the side walls of the bumper. This sound is not a malfunction but is a design feature.
