John Cage visited an anechoic chamber at Harvard University.

约翰·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零的房间。

Yeah, so we're in the historic anechoic chamber at Bell Labs.

是的，我们正在贝尔实验室的历史性消声室中。

It is anechoic, meaning it lacks echo.

这是一个消声室，意味着它没有声。

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

但这并非普通的储水池，而是我们所说的消声水池。

So an anechoic chamber is intended to absorb as close to 100% of incidental reflection as you can possibly do.

因此，消声室旨在吸收尽可能接近100%的反射声，以达到最佳的声学实验环境。

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，消声室的是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.

（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。

I feel like a lot of the sort of mainstream conversation about anechoic chambers is that it feels really freaky to be in them.

我觉得，关于消声室的很多主流讨论都让人觉得，待在里面真的很诡异。

And we were able to transmit the anechoic sounds, the sounds without reverberation, to an adjacent space and apply a new space in real time.

我们成功地将无声的声音，即无混响的声音， 传输到相邻的空间， 并实时应用到一个新的空间中。

Okay, so one of the kind of miraculous things about an anechoic chamber is it allows you to hear something that you can't hear outside of the chamber.

好的，消声室的一个神奇之处在于，它能让你听到在室外无法察觉的声音。

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。
