SOUND ABSORPTION PANEL
To provide a sound absorption panel having excellent sound absorbing performance.SOLUTION: A sound absorption panel 1 comprises: a front plate 23 arranged on a sound source side and having a through-hole; a sound insulation plate arranged behind the front plate 23; and sound absorption means arranged between the sound insulation plate and the front plate 23. The sound absorption means is composed of a protective material, a first sound absorption material, a resistance material, and a second sound absorption material, arranged in order from the sound source side. The protective material, the first sound absorption material, the resistance material, and the second sound absorption material all have air permeability. The resistance material is located at the center in the longitudinal direction of the sound absorption means or to the rear of the center. The sound absorption panel 1 is configured so that the flow resistance of the resistance material is larger than the flow resistance of both the first sound absorption material and the second sound absorption material.SELECTED DRAWING: Figure 1
【課題】良好な吸音性能を備える吸音パネルを提供する。【解決手段】透孔を有し音源側に配置される前面板２３と、前面板２３の後方に配置される遮音板、遮音板と前面板２３との間に配置される吸音手段とを備えた吸音パネル１であって、吸音手段は、保護材、第一の吸音材、抵抗材及び第二の吸音材が音源側から順に配置され、保護材、第一の吸音材、抵抗材及び第二の吸音材は、いずれも通気性を有し、抵抗材は、吸音手段の前後方向中央部、又は前記中央部よりも後方に位置しており、抵抗材の流れ抵抗は、第一の吸音材及び第二の吸音材の流れ抵抗よりも大きくなるように吸音パネル１を構成する。【選択図】図１
