The invention relates to a motor vehicle noise attenuation trim part comprising at least one porous layer wherein the porous layer comprises at least one closed container partially filled with loose particles, the closed container comprising a contact surface formed by a film for contacting a vibrating surface of a vehicle, and a surface of the membrane opposite the contact surface is in contact with at least a portion of the loose particles such that the membrane is capable of transferring vibrational energy from the vibrational surface to the loose particles inside the container.
本发明涉及一种包括至少一个多孔层的汽车噪音衰减装饰部件,其中,多孔层包括部分填充有松散颗粒的至少一个闭合容器,闭合容器包括由薄膜形成的用于接触车辆的振动表面的接触表面,并且薄膜的与接触表面相对的表面与至少一部分松散颗粒接触,使得薄膜能够将振动能量从振动表面传递到容器内部的松散颗粒。
