SOUND ABSORBING PANEL ASSEMBLY
A sound absorbing panel assembly (10) comprises a first sheet (11), a second sheet (12), a first frame structure (21) and a second frame structure (22). Each sheet (11, 12) comprises a polymer foam material and each sheet (11, 12) is provided with a plurality of backside-to-front side through-going perforations (31) that are arranged in a pattern covering at least a major part of the area of the backside and front side of each sheet(11, 12). The first frame structure (21) is arranged on the backside of the first sheet (11) and the second frame structure (22) is arranged on the backside of thesecond sheet (12). Furthermore, the first sheet (11) and the second sheet (11) are arranged in a sandwich arrangement in relation to each other such that the first frame structure (21) is attached tothe front side of the second sheet (12) and an air gap (13) is present between the sheets (11, 12).
一种吸声板组件(10)，包括：第一片材(11)、第二片材(12)、第一框架结构(21)和第二框架结构(22)。每个片材(11、12)包括聚合物泡沫材料，并且每个片材(11、12)设置有多个从背面到正面的贯穿的穿孔(31)，所述穿孔(31)以覆盖每个片材(11、12)的背面和正面的至少大部分区域的图案布置。第一框架结构(21)布置在第一片材(11)的背面，第二框架结构(22)布置在第二片材(12)的背面。此外，第一片材(11)和第二片材(11)相对于彼此以夹层布置方式布置，使得第一框架结构(21)附接到第二片材(12)的正面，并且在片材(11、12)之间存在空气间隙(13)。
