日本东京新国家歌剧院（ＮＮＴ歌剧院）容座 １８１０，容积 １４５００ ｍ３，（大幕开启时的）满场混响时间 １．５ ｓ。正厅池座基本是长方形，３组眺台的水平截面为扇形，而不同高度的跳台的挑口饰也组成一个长方形。设计上的独特之处在于，舞台前上方的大型弯曲的反射板，与３组左右侧眺台靠前的６个弯曲的反射面一起，构成了一个“声喇叭”。声喇叭，加上眺台外墙面和特定形状的天花板，将舞台上歌手的歌声无需电声设备就均匀分布到大部分观众座席区，而且那里歌手声音很容易盖过乐池中乐队的声音。
Japan Tokyo New State Opera House (NNT Opera House) Receptacle 1810, volume 14500 m3, (when the curtain opens) full field reverberation time 1.5 s. The main pool seat is rectangular, the horizontal cross section of the three groups of balconies is fan-shaped, while the different height of the mouthpiece of the jumping stage also forms a rectangle. The design is unique in that the large, curved reflector above the front of the stage, together with the six curved reflective surfaces in front of the three left and right viewing platforms, constitutes a “horn.” Acoustic horns, plus veranda walls and ceiling-shaped ceilings distribute the singer’s song on stage to most audience areas without the need for electro-acoustic equipment, and the singer’s voice can easily overwhelm the orchestra’s voice.
