John Cage visited an anechoic chamber at Harvard University.

翰·凯奇参观了哈佛大学的消声室。

Anechoic chambers are rooms that are acoustically treated to minimize sound to almost zero.

消声室是经过声学处理以将声音降至几乎的房间。

But this is not an ordinary tank, this is what we call an anechoic tank.

但并非普通的储水池，而是我们所说的消声水池。

So an anechoic chamber's design is to reduce the amount of sound to just as absolute - close to absolute zero as possible.

因此，消声室的设计就是将声音量降低到尽可能绝对值——接近绝对。

(Pulse) I've personally experienced an anechoic chamber, and it's a really wild experience that can completely change your perceptions about sound and silence.

（脉搏）我亲自体验过消声室，那是一种非常奇妙的体验， 可以完全改变你对声音和寂静的看法。

And when I went into the anechoic chamber, my perception of what sound is, the definition of quiet, the definition of silence - all of those terms changed in my mind.

当我进入消声室时，我对声音的理解、安静的定义、沉默的定义——所有些术语在我的脑海中都发生了变化。
