NASA has released audio of a black hole to give an insight into the vastness of the universe.
美国国家航空航天局（NASA）日前发布了一段黑洞的音频片段，让人类能更加了解宇宙的浩瀚。
The audio debunks the misconception that space has no sound because it's a vacuum.
这段音频揭穿了“太空中没有声音，因为它是真空的”这一误解。
NASA used the gas released by a nearby galaxy cluster to pick up the sound waves around the black hole.
NASA是利用附近星系团释放的气体，来接收黑洞周围的声波的。
The original noise is too low for the human ear to detect.
原始的声音频率太低，以至于人耳根本无法察觉。
The galactic groan is 144 quadrillion times higher than the original frequencies picked up by NASA.
银河系噪声的频率，要比美国国家航空航天局（NASA）接收到的原始频率高144万亿倍。
"There are parts of space that are really really dense, really really compacted with dust and gas.
“太空的某些区域非常非常紧密，被尘埃和气体压得非常非常紧实。
And if you were in those regions, you potentially could hear something.
只有你身处这些区域，你才可能会听到一点声音。
These sound waves though were so low-pitched, we could not hear them."
这些声波音调很低，我们是无法听到的。”
Scientists used a process known as sonification to re-synthesize the sound waves into the range of human hearing.
科学家们是通过一种被称为声音可听化的过程，将声波重新合成到人类的听觉范围内。
