Sound-absorbing member, sound-absorbing panel, and sound-absorbing wall
The sound-absorbing unit (10) has a plurality of hollow portions having different shapes and/or sizes from each other. A perforated plate (20) that constitutes the walls of the plurality of hollow parts has formed therein perforations that communicate the inside and the outside of the hollow parts. The surface of the perforated plate (20) includes a perforated region, which is a region in which a plurality of perforations are formed, and a non-perforated region, which is a region in which no perforations are formed.
吸音单元(10)具有形状和大小中的至少任一方互不相同的多个空洞部。在构成多个空洞部所包括的空洞部的壁的穿孔板(20)形成有使空洞部的内部与外部连通的穿孔。穿孔板(20)的表面包括穿孔区域和非穿孔区域,所述穿孔区域是形成有多个穿孔的区域,所述非穿孔区域是未形成穿孔的区域。
