Abstract
A sound-absorbing structure in a vehicular compartment can prevent the air within the compartment from passing out through the lining and thus prevent deposition of dust onto the inner surface of the lining. The structure includes a panel forming part of a vehicular body and allowing air leakage, a porous sound-absorbing lining separated from the inner surface of the panel by a space and a partition for preventing air leakage, the partition being air-impermeable and disposed in the space. The lining and the partition define an air chamber enhancing the sound-absorbing properties of the lining.
