John Cage visited an anechoic chamber at Harvard University.

约翰凯了哈佛大学的消声室。

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能绝对值——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) 我亲身体过消声室，那是一次真正狂野的体， 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——所有这些术语在我的脑海中都发生了变化。
