Do you hear "Yanny" or "Laurel"? A recent Twitter poll found that 47 percent of people hear "Yanny," while 53 percent hear "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," 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, created by Brad Story, a professor of speech, language, and hearing.
第二，你說話的時候會產生聲波，那會經由空氣傳導。這是原始的 Yanny/Laurel 音檔聲波圖像，由聽力語言學教授 Brad Story 創造的。
Here is the depiction of him saying "Laurel." You can see that the acoustic features are very similar. Here is a depiction of him saying "Yanny." The acoustic features are also similar. So the words "Yanny" and "Laurel" audibly are more similar than you might think.
Whether you're listening on a laptop, phone, or headphones will influence what you hear based on sound quality. But what if you are 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." As we age, our ears are less able to hear higher frequencies. So if you are hearing "Yanny", you might have younger ears.
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. When you listen to it brought down 30 percent, you'll hear "Yanny."
幸運的是，透過網路的幫助，我們兩種都聽得到。聰明的推特用戶 @xxv 發佈了將音頻調高和調低的音檔。當你聆聽音頻拉低百分之三十的音檔，你會聽到「Yanny」。
But when you listen to it with the pitch brought up 30 percent, you will likely hear "Laurel."
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...what is the final answer? If you heard "Laurel," you are correct! The original recording is saying "Laurel" but with higher frequencies overlaid creating ambiguity.
