SETTING METHOD OF SOUND INSULATION LOUVER
To provide a setting method for appropriately securing sound insulation performance of a sound insulation louver consisting of a louver blade member into which resonators having the same cross-section are incorporated.SOLUTION: A first resonator 10a having a slit-like opening 50 is arranged on a first main surface 4 of a louver blade member 3, and a second resonator 10b is arranged on a second main surface 5 of the louver blade member 3. When a distance between the first main surface 4 and the second main surface 5 in one louver blade member 3 is defined as t', a distance between the slit-like opening 50 of the first resonator 10a and the slit-like opening 50 of the second resonator 10b in one louver blade 3 is defined as w', and a distance between the one louver blade member 3 and the louver blade member 3 arranged adjacent thereto is defined as d', an angle θ in which the first main surface 4 and the second main surface 5 of the louver blade member 3 form a horizontal direction is set by θ=tan-1{w'/(t'+d')}.SELECTED DRAWING: Figure 4
【課題】同一断面を有する共鳴器を組み込んだルーバー羽根部材からなる遮音ルーバーの遮音性能を適切に確保することができる設定方法を提供する。【解決手段】スリット状開口部５０を有する第１共鳴器１０ａが、前記ルーバー羽根部材３の第１主面４に配され、第２共鳴器１０ｂが、前記ルーバー羽根部材３の第２主面５に配され、一つのルーバー羽根部材３の中での前記第１主面４と、前記第２主面５との間の距離をｔ’とし、一つのルーバー羽根部材３の中での第１共鳴器１０ａのスリット状開口部５０と、前記第２共鳴器１０ｂのスリット状開口部５０との間の距離ｗ’とし、一の前記ルーバー羽根部材３と、これに対して隣に配置される前記ルーバー羽根部材３との間の距離をｄ’とするとき、前記ルーバー羽根部材３の前記第１主面４及び前記第２主面５が水平方向となす角度θをθ＝ｔａｎ-1｛ｗ’／（ｔ’＋ｄ’）｝より設定することを特徴とする。【選択図】図４
