SOUND ABSORPTION BODY AND SOUND ABSORPTION WALL
To provide a sound absorption body and a sound absorption wall that are free of trouble such as wrinkling of a surface or a decrease in sound absorption performance even when fire-resistant covering fabric with no elasticity is used.SOLUTION: A sound absorption body (interior panel) 35 comprises a plate-like member 36 which has firmness, urethane 37 added to the plate-like member 36, and fire-resistant covering fabric 38 which covers an outer side of the urethane 37. The fire-resistant covering fabric 38 and urethane 37 are bonded together by hot melting.SELECTED DRAWING: Figure 8
【課題】伸縮力のない非燃性の張地を用いた場合であっても、表面に皺が発生する不具合や吸音性能が低下するという不具合を招くことのない吸音体及び吸音壁を提供する。【解決手段】吸音体（内装パネル）３５は、保形性を有した板状部材３６と、板状部材３６に添設されたウレタン３７と、ウレタン３７の外側を覆う非燃性張地３８とを備える。非燃性張地３８とウレタン３７とは、ホットメルトにより接着されている。【選択図】図８
