Reverberation Time Determines Hall Usage

Reverberation time determines the hall's purpose. A comparison screen of three halls. The drama hall's walls and ceiling are covered with sound-absorbing materials, its volume is small and compact, aiming for clear dialogue; the opera house has a medium volume, with both reflective and sound-absorbing surfaces on the side walls; the concert hall has the largest volume, entirely made of hard reflective surfaces, almost no sound absorption. The same team hears completely different things in the three halls. Avoid: drawing the three halls with the same materials and volume, extensively using soft sound-absorbing panels in the concert hall, making the drama hall a tall, hard-surfaced space, ignoring that each seat itself is also a sound-absorbing body.

三個廳的比較畫面。話劇廳的牆面與天花佈滿吸音材,體積小而緊湊,追求台詞清楚;歌劇院體積中等,側牆有反射面也有吸音;音樂廳體積最大,全部是硬質反射面,幾乎不吸音。同一個團隊在三個廳裡聽到的完全不一樣。避免:三個廳畫成同樣的材料與體積、在音樂廳大量使用軟包吸音、把話劇廳做成高大的硬面空間、忽略每座椅本身也是吸音體。
