SOUND OUTPUT UNIT AND SOUND MASKING FACILITY
To create a natural sound field by diffusing a sound to a space where a user presences, while avoiding a direct input of the sound for masking the sound to a collection sound microphone mounted on a top board of furniture with the top board.SOLUTION: A sound output unit 1 is installed in a lower floor between a floor slab 4 in a double-floor in which a floor panel 5 is laid so as to be floated from the floor slab 4 of a building construction and the floor panel 5, and makes a sound S reach a floor space on an upper direction of the floor panel 5 after the sound S is propagated in the floor space by outputting the sound S toward a horizontal direction or an oblique direction tilted from a vertical direction.SELECTED DRAWING: Figure 4
【課題】天板付家具の天板上に載置された集音マイクにサウンドマスキング用の音声が直接入力されることを回避しつつ、ユーザが所在する空間に音声を拡散させてより自然な音場を作出する。【解決手段】建築構造物の床スラブ４から浮上させて床パネル５が敷設された二重床における床スラブ４と床パネル５との間の床下空間に設置され、水平方向または鉛直方向から傾倒した斜め方向に向けて音声Ｓを出力することにより、床下空間内で音声Ｓを伝播させた上で床パネル５の上方の床上空間に音声Ｓを到達させる音声出力ユニット１を構成した。【選択図】図４
