SOUND ABSORBING CEILING MEMBRANE
PROBLEM TO BE SOLVED: To provide a sound absorbing ceiling membrane that excels in reverberation suppressing and sound attenuating effects as ceiling area constituting members and accessory material for ceiling area constituting members for indoor sports competition facilities, gymnasiums, indoor swimming pools, performance event halls, public auditoriums, ceremonial event facilities and so forth, and moreover readily permits sewing by high-frequency fusion.SOLUTION: Many ventilation holes of 0.5 to 1.5 mm in bore are so formed and arranged in a scattered way all over a flexible laminate of 0.5 to 2.0 mm in thickness as to form the stratified structure of the inner wall sections of the ventilation holes in a thermoplastic resin layer/fabric cloth layer/thermoplastic resin layer pattern with the result that at least mutually adjoining ventilation holes are continuous in ventilation with the fabric cloth layer in-between.SELECTED DRAWING: Figure 1
【課題】屋内競技場、体育館、屋内プール、イベントホール、公会堂、冠婚葬祭式場などの天井面積構成部材、天井面積構成部材付帯物として、反響抑止効果と音響減衰効果とに優れ、しかも高周波融着による縫製の簡便性を兼備する吸音天井膜の提供。【解決手段】厚さ０．５〜２．０ｍｍの可撓性積層体の全面に孔径０．５〜１．５φｍｍの通気孔を散在して多数形成、配置し、通気孔の内壁断面の層構造を、熱可塑性樹脂層／繊維布帛層／熱可塑性樹脂層、とし、少なくとも互いに隣接する通気孔同士が繊維布帛層を介在して通気連続するようにする。【選択図】図１
