John Cage visited an anechoic chamber at Harvard University.

约翰凯奇参观了哈佛大学的消声。

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

消声经过声学处理以将声音降至几乎零的房间。

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，消声的设计就将声音量降低到尽可能绝对值——接近绝对零。

(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.

(Pulse) 我亲身体验过消声，一次真正狂野的体验， 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.

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