一、Music and Noise 托福红Delta听力原文：

W:Well,I don’t know about you,but I’m totally confused about today’s lecture,especially the part about music and noise.

M:It’s not so bad,really.I think I got‘most everything in my notes.

W:So then...what is the difference between music and noise?Professor King said noise is a random sound,but then he said the sounds of a cymbal and a drumbeat were examples of noise.I’d say they’re examples of music—since they’re sounds made by musical instruments!What do you think he meant?

M:OK.Do you remember how he said that noise is a random sound?

W:Uh-huh.

M:Well,it’s a random sound that has irregular sound waves.

W:But how’s a sound that’s noise different from a sound that’s music?

M:Well,if you could take a picture of a musical note,you’d see that it has regular waves that repeat themselves.That’s because music is a sound that’s in a pattern we can hear or discern.Noise is different from music because it doesn’t have a pattern.W:But why is the sound of a drumbeat noise instead of music?Isn’t a drumbeat a note?And then...so...doesn’t it have a regular pattern of waves?

M:Maybe you’re taking what he said too literally.Maybe he meant a drumbeat is as close as a musical instrument can get to making just noise.

W:Maybe a single drumbeat is like a word spoken out of context.A single word with no context is just noise!

M:Now there’s a thought!

W:The other thing I didn’t get was what he said about antinoise.First noise,then antinoise?What do you think he meant?

M:Think of it as the opposite of noise.It’s like—wait,let me back up.Sound has waves,right?

W:Right.M:Well,we can describe these waves as“in phase”or“out of phase”with each other.“Out of phase”means reversed.

W:Uh-huh.

M:If you add two out-of-phase waves together at the same frequency,the result is antinoise—silence.

W:Antinoise is silence?

M:Right!And there’s a computer program that proves this.A microphone picks up the sound and sends it back to the computer,and then the computer reads the waves and makes sort of a mirror image,or a reverse copy of the wave.Then you can play it back against the original sound,and when the two waves meet,they sort of overlap each other...exactly at the high and low peaks.This eliminates the sound,creating zero sound—antinoise.

W:How do you know all this?Professor King didn’t talk about this.

M:It’s all in our book.Didn’t you do the reading?

W:No,I didn’t have time.I guess I’d better do that now.

M:Yeah,you should.But it’s better to do the reading before the lectures‘cause then you’ll have a better idea of what he’s talking about.

W:Yeah,you’re right.I guess I have some catching up to do.

二、Music and Noise 托福红Delta听力中文翻译：

W：嗯，我不知道你是怎么想的，但我对今天的讲座，尤其是关于音乐和噪音的那部分，感到非常困惑。

M：真的没那么糟。我想我的笔记里几乎什么都有。

W：那么。。。音乐和噪音有什么区别？金教授说，噪音是一种随机的声音，但后来他说，钹和鼓声就是噪音的例子。我要说，它们是音乐的例子，因为它们是乐器发出的声音！你认为他是什么意思？

M：好的。你还记得他怎么说噪音是随机的吗？

W：嗯哼。

M：这是一种随机的声音，有不规则的声波。

W：但是作为噪音的声音和作为音乐的声音有何不同呢？

M：如果你能拍下一个音符的照片，你会发现它有规则的波，它们会自动重复。那是因为音乐是一种我们可以听到或辨别的声音。噪音与音乐不同，因为它没有规律。W：但是为什么鼓声是噪音而不是音乐呢？鼓声不是音符吗？然后。。。所以它不是有规律的波浪吗？

M：也许你把他说的话看得太字面了。也许他的意思是鼓声离乐器发出噪音的距离很近。

W：也许一个鼓点就像一个断章取义的词。一个没有上下文的单词就是噪音！

M：现在有一个想法！

W：另一件我不明白的事是他对安蒂诺尼斯的看法。先是噪声，然后是抗噪声？你认为他是什么意思？

M：把它想象成噪音的反面。就像等等，让我退后。声音有波，对吗？

W：对。M：我们可以把这些波描述为彼此“同相”或“异相”。“异相”指反向。

W：嗯哼。

M：如果在同一频率下将两个异相波相加，结果就是抗噪声静音。

W：Antinoise是沉默？

M：对！有一个计算机程序可以证明这一点。麦克风拾取声音并将其发送回计算机，然后计算机读取波形并制作镜像或波形的反向副本。然后你可以播放原始声音，当两个波相遇时，它们有点相互重叠。。。正好在高峰和低谷。这样可以消除声音，从而产生零噪声。

W：你怎么知道这些？金教授没有谈到这件事。

M：这都在我们的书里。你没有做阅读吗？

W：没有，我没有时间。我想我最好现在就这样做。

M：是的，你应该。但最好在上课前阅读，因为这样你就能更好地了解他在说什么。

W：是的，你说得对。我想我还有一些事情要做。
