1 .A few years back, psychologists at the University of California, San Diego, discovered that when words or phrases are repeated a few times, they can start to sound more like singing than speaking.

1 .("The sounds as they appear to you are not only different from those that are really present, but they sometimes behave so strangely as to seem quite impossible.

7 .Talking and singing are both forms of vocal communication.
因为说话和唱歌都是口头交流的形式。
8 .But researchers got to wondering: could repetition also musicalize other types of sounds?
但是研究人员想知道：重复是否也能音乐化其他类型的声音？

1 .So they collected clips of 20 different environmental sounds...including water dripping, ice cracking, whales calling, and the aforementioned shovel.
所以，他们收集了20种不同环境中的声音片段，其中包括水滴落的声音、冰裂声、鲸鱼叫声以及前面提到的铲子声。
2 .And they played the snippets to 58 undergraduates...first, as single sounds (single whale call) and then in a series with increasing reiteration (whale call repeated).
然后，他们给58名大学生播放了这些声音片段，首先是单一的片段（单次鲸鱼叫声），然后播放一系列不断重复的声音（重复的鲸鱼叫声）。
3 .What they found is that...as the repeats stacked up...the participants rated the sounds as being more tuneful.
他们发现，重复次数增加时，参与者认为这些声音变得更加悦耳。

1 ."These perceptual transformations are powerful because nothing changes in the acoustic signal itself.
“这些感知转换很强大，因为声音信号本身没有任何变化。
2 .That is held fixed.
那是恒定不变的。
3 .Everything that sounds different comes from the mind itself, making these illusions particularly useful for understanding the musical mode of listening.
所有听起来不同的声音都来自于思维本身，这使这些错觉对于理解听觉的音乐模式尤为有用。
4 .What are we doing when we're hearing something musically?
我们在听到具有音乐性的声音时会有什么反应？
5 .How is this different from other kinds of hearing?
与听到其他类型的声音有什么不同？
6 .These transformations allow us to tackle these kinds of questions head on."(ice crack sound repeated)
