Broadband sound absorber |
| abstract |
The invention relates to a broadband sound absorber ( 1 ) which comprises a sound-absorbing filler material between two microperforated film webs ( 2 ) which are contiguous on their edges, said filler material optionally containing heavy fillers. The broadband sound absorber ( 1 ) achieves excellent acoustic insulation and has microperforations ( 4 ) all over or only in sections, said filler material optionally containing heavy fillers (mass density) and one or both microperforated film webs ( 2 ) having the same thickness across their surface or thickened portions ( 3, 5 ) of the same or a different material in some sections. |
