Acoustic damper for soundproof capsules and cabins

摘要

The acoustic damper comprises an outer (4) and inner (6) wall which form a hollow interior filled with sound absorption material. Profiled sections (8, 10) are fitted to the longitudinal edges (12, 14) as angled sections (24, 26) of the walls (4, 6). These angled sections grip together in a shape fit lock which holds the walls together. The profiled sections project from the respective longitudinal edges over side sections (20,21) in such a way that they form hooks. The profiled sections engage behind with neighbouring dampers thus locking them together. The distances between the hook projections and the side wall are equal.
