To suppress standing waves without impairing convenience and design in a space.SOLUTION: An acoustic chamber 1 comprises: an acoustic space 2 in which an acoustic path is formed between lateral walls 1a, 1b; and an acoustic tube 3 having an opened one end 3a and a closed another end 3b and having a tube length from the one end 3a to the other end 3b which is approximately 1/2 times as long as the acoustic path length, wherein the acoustic tube 3 extends to the outside of the acoustic space by connecting the acoustic space 2 and the one end 3a at or near the lateral wall 1b.SELECTED DRAWING: Figure 1
【課題】空間内の利便性や意匠性を損なわずに定在波を抑制する。【解決手段】音響室１は、横壁１ａ、１ｂ間に音響路が形成された音響空間２と、開口された一方端３ａと、閉塞された他方端３ｂと、を有し、一方端３ａから他方端３ｂまでが音響路長の略１／２倍の管長を有する音響管３と、を備え、音響管３は、横壁１ｂ又はその近傍で音響空間２と一方端３ａが連結されて当該音響空間の外側へ延在している。【選択図】図１
