摘要： An in-tire sound absorber for a pneumatic wheel assembly including a wheel rim and a tire fitted to the wheel rim. The sound absorber comprises a first fibrous layer and a second fibrous layer with a higher air flow resistance than the first layer. The sound absorber is configured to fit around the wheel rim with the first layer in contact with a surface of the wheel rim and extending substantially between the second layer and the wheel rim.

摘要： Described embodiments relate to a method of manufacturing a sound absorption material. The method comprises: forming a low density fibrous web to act as a porous bulk absorber, the fibrous web containing a proportion of bi-component fibers, each bi-component fiber having a core material and a sheath material around the core material, the sheath material having a lower melting point than the core material; applying a thin facing layer to the low density fibrous web, wherein the facing layer is adhesively compatible with the sheath material; heating the fibrous web to a temperature sufficient to soften the sheath material of at least some of the bi-component fibers; and pressing the facing layer and fibrous web together under low pressure such that at least part of the facing layer contacts the softened sheath material of at least some of the bi-component fibers to form an adhesive bond between the facing layer and the fibrous web.
