To provide an audio room in which transmission characteristics of a low frequency band are flat.SOLUTION: An audio room 10 of the present invention has an inner wall polyhedron 16 formed of a polyhedron formed inside an outer wall 14 of a polyhedral room. At least one plane of the inner wall polyhedron 16 has a rear face sound absorbing layer 11 formed by filling a sound absorbing material between the outer wall 14 and the plane, and sound absorbing openings 12 exposing a reflection part 13 and the rear face sound absorbing layer 11 are provided to the inner wall polyhedron 16. A vertical section of the rear face sound absorbing layer 11 at a circumference of the sound absorbing opening 12 serves as a sound absorbing section 15, an indoor space is made to communicate with the rear face sound absorbing layer 11 via the sound absorbing section 15, and four times of the total area of the sound absorbing section 15 is set to be larger than a surface area of the inner wall polyhedron 16.SELECTED DRAWING: Figure 1
【課題】本発明は、低域の周波数伝送特性が平坦となるオーディオルームを提供することを目的とする。【解決手段】本発明のオーディオルーム１０は多面体１４の室の外壁の内側に作られる多面体を内壁多面体１６とし、前記内壁多面体１６の少なくとも１つの平面が、外壁１４と前記平面の間に吸音材を充填して成る背面吸音層１１を備え、内壁多面体１６に反射部１３と背面吸音層１１が露出する吸音開口部１２を設け、吸音開口部１２の周における背面吸音層１１の垂直断面を吸音断面１５とし、吸音断面１５を介して室内空間と背面吸音層１１が通ずるようにし、吸音断面１５の総面積の４倍の面積が内壁多面体１６の表面積以上となるように構成される。【選択図】図１
