A room is a listening environment一個場，是一個聆聽環境

When a room is loud, people stop talking. It is rarely because the music is too loud in general: speech and music are occupying the same space, and the conversation loses.場一嘈，人就不交談。多數不是音樂太大聲，而是人聲與音樂爭同一個位置，最後說話的一方輸。

Turning it down flattens the night instead of fixing it. What changes a room is where the sound comes from, which frequencies are left clear for speech, and whether different zones are allowed to sound different.只是調小聲不會修好一個場，只會令整晚沉悶。真正改變場地的是三件事：聲音從哪裡來、留哪段頻率給人說話、不同區域可不可以有不同聲音。

That is a decision about how people behave, and it should be made before any equipment is chosen. The equipment is only how the decision gets implemented.這件事是設計人如何行動，要在選擇器材之前決定。器材只是實現方法。
