    SOUND ABSORPTION STRUCTURE AND SOUND PROOF ROOM

    Neue Suche nach: GEN HARUO

    PROBLEM TO BE SOLVED: To improve sound absorption performance with a simple structure.SOLUTION: A sound absorption structure (1) includes a back surface part (21) having a length in a predetermined direction, a front surface part (22) disposed in parallel with the back surface part (21) and away from the back surface part (21) frontward, and a sound absorption member disposed between the back surface part (21) the front surface part (22). The front surface part (22) has an opening (23) through which sound passes, and a sound absorption member (3) is arranged at least behind a reflection wall part (220) excluding the opening (23) in the front surface part (22).SELECTED DRAWING: Figure 1

    【課題】簡易な構造で、吸音性能を向上させること。【解決手段】吸音構造（１）は、所定方向に長さを有する後方面部（２１）と、後方面部（２１）と平行かつ後方面部（２１）から前方に離れて配置された前方面部（２２）と、後方面部（２１）と前方面部（２２）との間に配置される吸音材とを備える。前方面部（２２）には音を通過させるための開口部（２３）が設けられており、吸音材（３）が、少なくとも、前方面部（２２）のうちの開口部（２３）を除く反射壁部（２２０）の背後に配置されている。【選択図】図１
