Yanny, Laurel, or Covfefe?
Yet another viral debate popped up this week after audio surfaced on the internet that had some listeners hearing the name “Laurel” while others heard “Yanny.” This was obviously confusing to many. How could so many people hear one word while the other half of the population heard something completely different?
If you haven’t listened yet, here is the tweet that started the great debate:

Well, actually, both listeners are right. The audio featured the word “Laurel” as well as “Yanny.” Depending on a range of factors, our brain effectively chooses what word we hear for us. The Verge has a pretty decent explanation of this conundrum:
“According to Lars Riecke, an assistant professor of audition and cognitive neuroscience at Maastricht University, it’s not actually an illusion. In fact, it’s an ambiguous figure, the auditory equivalent of two figures in profile that also form a vase, called Rubin’s vase. “The input can be organized in two alternative ways,” he says.
The acoustic information that makes us hear Yanny is higher frequency than the acoustic information that makes us hear Laurel. Some of the variation may be due to the audio system playing the sound, Reicke says. But some of it is also the mechanics of your ears, and what you’re expecting to hear.
Older adults tend to start losing their hearing at the higher frequency ranges, which could explain why Riecke could only hear Laurel, but his eight-year-old daughter could hear Yanny. It’s a phenomenon you can mimic on a computer, he says: if you remove all the low frequencies, you hear Yanny. If you remove the high frequencies, you hear Laurel.”
Here’s another tweet showing what happens what the frequency is adjusted:

As the debate raged throughout the nation, so too did the viral video throughout the White House.
The video shows various White House staffers and officials such as Deputy Press Secretary Raj Shah, Kellyanne Conway, Executive Assistant Madeleine Westerhout, and Vice President Mike Pence chiming in their opinion. Finally, the video ends with President Donald J. Trump himself offering his feedback. The word he hears is “covfefe,” a humorous reference to his accidental Tweet in 2017 that went viral.
