| 摘要 |
The invention relates to structures that are made of hard materials, similar to a skeleton, which are embedded in softer materials (e.g., elastomer). Not only can the sound transmission be greatly limited thereby, but also other functional advantages can be achieved thereby, such as the reduction of the number of parts, because formations can be produced from the embedding material, such as seals, cable passages, membranes, and elastic suspension elements, etc. A special variant of said structures is the light anti-humming layer having a thickness of approx. 1 mm, which greatly reduces humming noises, for example when adhesively bonded to a car door. |
