  • Do you hear Yanny

    你聽到的是 Yanny

  • or Laurel

    還是 Laurel ?

  • A recent Twitter poll found, that 47% of people hear "Yanny", while 53% hear "Laurel"

    最近在推特上有一個民調發現有 47 % 的人會聽到 Yanny , 另外 53 % 則會聽到 Laurel

  • Clearly this has created an internet argument that is dividing the nation


  • So what is the science behind the madness?


  • One of the first aspects is priming


  • If you were to play this clip without providing the option of "Yanny" or "Laurel"

    如果你在聽這個錄音檔前沒有被提供 Yanny 或 Laurel 這兩個選項

  • you may have heard neither of these words


  • But by reading them, you're primed to hear one or the other.


  • Secondly when you speak you are producing sound waves, which propagate through the air


  • This is a visual depiction of the sound waves of the original Yanny/Laurel recording

    由語言學教授 Brad Story 所創的 Yanny/Laurel 音欓的聲波長這樣

  • created by Brad Story, a Professor of Speech, Language, and Hearing

    由語言學教授 Brad Story 所創的 Yanny/Laurel 音欓的聲波長這樣

  • Here is the depiction of him saying "Laurel"

    這是他說 Laurel 時的聲波

  • You can see that the acoustic features are very similar


  • Here is a depiction of him saying "Yanny"

    這是他說 Yanny 時的聲波

  • The acoustic features are also similar


  • So the words "Yanny" and "Laurel" audibly are more similar than you might think

    所以 Yanny 和 Laurel 這兩個字聽起來比你想像中的還要相似許多

  • Whether you're listening on a laptop, phone or headphones


  • will influence what you hear based on sound quality


  • But what if you were listening through the same device but you hear different things with someone next to you


  • It might have to do with the age of your ears


  • The sounds in "Yanny" play at a higher frequency than the sounds in "Laurel"

    Yanny 的聲波頻率比 Laurel 來得高

  • As we age, our ears are less able to hear higher frequencies


  • So if you are hearing "Yanny", you might have younger ears

    所以如果你到的是 Yanny ,就代表你的耳朵很有可能比較年輕

  • Luckily with the help of the internet, we can hear both


  • Brilliant twitter user @xxv posted audio of the pitch brought both down and up

    冰雪聰明的一位推特用戶 @xxv 發了一個音檔把原先的檔案音調調高和調低

  • When you listen to it brought down 30%, you will hear "Yanny"

    當我們把音調調低百分之 30 ,你將會聽到 Yanny

  • Yanny x2

    Yanny x2

  • But when you listen to it with the pitch brought up 30%, you will likely hear Laurel

    但如果我們把音調調高百分之 30 ,你很有可能會聽到 Laurel

  • Laurel x2

    Laurel x2

  • Your brain has so much stimulus at all times that it uses existing information and precise neurological pathways to focus its attention


  • This is why at a loud party you can listen to your friend beside you


  • but pop your attention into another convo if need be


  • Similarly, your brain is unconsciously choosing which frequencies in the recording to pay attention to so


  • So... What is the final answer?

    所以...原音檔究竟是說 Yanny 還是 Laurel 呢?

  • If you heard "Laurel", you are correct! The original recording is saying Laurel

    如果你聽到的 Laurel ,那麼你是正確的!原本的音檔就是說 Laurel

  • but with higher frequencies overlaid, creating ambiguity


  • Love learning about amazing and interesting things in the world?


  • We actually just started a brand new podcast called "SIDENOTE"

    我們最近新增了一個 podcast 的頻道叫做 SIDENOTE

  • where we explore the things that are stumping us or making us curious in life


  • and then insert all the mind-blowing science behind it


  • We'd love for you to check it out on iTunes or whichever podcast app you use

    歡迎你們到 iTunes 或是其他你在使用的軟體來追蹤收聽

  • Your support means a ton to us as we slowly journey into exploring more science in a new medium


  • Again it's called SIDENOTE and it's brand new, so we're excited to know what you think

    再說一次它叫做 SIDENOTE 熱騰騰剛出爐的 podcast ,我們很期待聽到你的回饋

  • We'll leave some links below


  • And subscribe for more weekly science videos every Thursday
