你听到的是Yanny还是Laurel?科学为你答疑

Do You Hear "Yanny" or "Laurel"? (SOLVED with SCIENCE)

你是听到yanny
Do you hear yanny
还是laurel
or laurel
最近的一项推特投票表明 47%的人听见yanny 而53%的人听见laurel
A recent Twitter poll found, that 47% of people hear”yanny”, while 53% hear”laurel”
无疑这已经造成了一场
Clearly this has created an internet
分裂国家的互联网大争论
argument that is dividing the nation
所以这场疯狂背后是什么原理呢
So what is the science behind the madness?
其一是启动效应
One of the first aspects is priming
如果你播放这个片段 但并不提供yanny和laurel这两个选项
If you were to play this clip without providing the option of”yanny” or”laurel”
你可能一个单词也听不出来
you may have heard neither of these words
但是读过这两个单词后 你就在听到的声音中选择一个接近的
But by reading them, you’re primed to hear one or the other.
其次 当你说的时候你会产生声波
Secondly when you speak you are producing sound waves,
它通过空气传播
which propagate through the air
这是一个关于原视频
This is a visual depiction
yanny和laurel录音的声波的视觉上的描述
of the sound waves of the original yanny/laurel recording
它被Brad Story 一个语音 语言 听力的教授所创建
created by Brad Story, a Professor of Speech, Language, and Hearing
这是他说laurel时的声波图
Here is the depiction of him saying”laurel”
你可以看到声学特征十分相似
You can see that the acoustic features are very similar
这是他说yanny时的描述
Here is a depiction of him saying”yanny”
声学特征也十分相似
The acoustic features are also similar
所以yanny和laurel其实听起来比你想的更为相似
So the words”yanny” and”laurel” audibly are more similar than you might think
无论你用笔记本电脑 手机还是耳机听
Whether you’re listening on a laptop, phone or headphones
音质会影响你听到的结果
will influence what you hear based on sound quality
但是如果你通过
But what if you were listening
相同的设备听但是却和你旁边的人听到了不同的内容
through the same device but you hear different things with someone next to you
这也许与你耳朵的年龄有关
It might have to do with the age of your ears
yanny的声音比laurel频率更高
The sounds in”yanny” play at a higher frequency than the sounds in”Laurel”
随着年龄的增长
As we age,
我们的耳朵听到高频率的声音的可能性会更小
our ears are less able to hear higher frequencies
所以如果你听到yanny 你可能拥有更年轻的耳朵
So if you are hearing”yanny”, you might have younger ears
幸运的是 有了互联网的帮助 这两个单词我们都能听见
Luckily with the help of the internet, we can hear both
聪明的推特用户@xxv上传了

音调调高和调低的音频
of the pitch brought both down and up
当你听调低30%的音频时 你会听到yanny
When you listen to it brought down 30%, you will hear”yanny”
yanny
yanny x2
但是调高30%
But when you listen to it with the pitch brought up 30 %,
你更有可能听到laurel
you will likely hear laurel
laurel
laurel x2
你的大脑一直有很多的刺激物
Your brain has so much stimulus
它们利用已存在的信息和精确的神经学通道来集中注意
at all times that it uses existing information and precise neurological pathways to focus its attention
这也是为什么在吵闹的派对上
This is why
你能听见你朋友的声音
at a loud party you can listen to your friend beside you
但如果需要也能把注意力转移到另一个频率上
but pop your attention into another convo if need be Similarly,
与此类似的啥你的大脑无意识地选择了一种频率
your brain is unconsciously choosing which frequencies
去加以注意 所以
in the recording to pay attention to so So…
最终的答案是什么
What is the final answer?
如果你听到laurel 你是正确的 原始的录音就是laurel
If you heard”laurel”, you are correct! The original recording is saying laurel
但是被更高的频率覆盖 便模棱两可了
but with higher frequencies overlaid, creating ambiguity
喜欢了解世界各地有趣的事情
Love learning about amazing and interesting things in the world?
事实上我们新创了一个名叫SIDENOTE的播客
We actually just started a brand new podcast called”SIDENOTE”
在那里我们探索
where we explore the things that
震惊我们的或令人好奇的事情
are stumping us or making us curious in life
然后插入它们背后给人印象极深的科学
and then insert all the mind-blowing science behind it
我们很希望你来看看
We’d love for you to check it out
无论你使用的是iTunes还是其它的播客软件
on iTunes or whichever podcast app you use
你的支持对我们很重要 尤其是在我们缓慢
Your support means a ton to us as we slowly journey
在一个新媒介上探索更多科学的时候
into exploring more science in a new medium
再一次 它叫SIDENOTE而且是全新的
Again it’s called SIDENOTE and it’s brand new,
所以我们期待你的意见
so we’re excited to know what you think
我们会放上链接和订阅
We’ll leave some links below And subscribe
为了更多的每个星期四周更科学视频
for more weekly science videos every Thursday
