SOUND ABSORBING BODY AND AUDIO ROOM INSTALLING THE SAME
PROBLEM TO BE SOLVED: To provide an inexpensive sound absorbing body simple in structure having a sound absorbing capability over a wide spectrum and usable for adjustment of a reverberation time of an individual audio room.SOLUTION: A sound absorbing body 10 is configured to sandwich a bottom face of an acoustic resistance body 14 formed in a flat shape, a sound insulation plate A12, and the bottom face of a sound insulation plate B13 so as to be closely attached one another between the sound insulation plate A12 and the sound insulation plate B13. The product of an attenuation constant of an attenuation evaluation distance which is the minimum value of a distance between two points where a linear line passing through an outer edge of a region where the whole of the sound insulation plate A12, the sound insulation plate B13, and the acoustic resistance body 14 are superposed and a geometrical centroid point of the region crosses the outer edge is controlled to 0.5 or more.
【課題】本発明は、簡便な構造で広帯域に吸音力を有し、個人のオーディオルームの残響時間の調整に使える安価な吸音体を提供することを目的とする。【解決手段】本発明の吸音体１０は平たい形に成型された音響抵抗体１４を遮音板Ａ１２と遮音板Ｂ１３の間に音響抵抗体１４の底面と遮音板Ａ１２と遮音板Ｂ１３の底面が密着するように挟んで構成される。また、遮音板Ａ１２と遮音板Ｂ１３と音響抵抗体１４の全部が重なっている領域の外縁と前記領域の幾何学的重心点を通る直線が前記外縁と交わる二点間の距離の最小値である減衰評価距離と音響抵抗体１４の減衰定数の積を０．５以上とする。【選択図】図１
