If you are reading this, you are likely one of the more than 14 million people who vehemently believe that this audio clip is saying either the word “Yanny” or the word “Laurel.”

What do you hear?! Yanny or Laurel pic.twitter.com/jvHhCbMc8I

The short audio clip has sharply divided the Internet since it was posted by Twitter user Cloe Feldman on Monday. Why would people hear two totally different words?
To answer this, we consulted experts in how human brains perceive sound.
Nina Kraus, a neurobiology professor at Northwestern University, says that “it is not at all surprising to me that two different people will take a sound that is admittedly acoustically ambiguous and hear it differently.”
“Acoustically ambiguous” in this case means that it’s a very poor quality file. That’s crucial in explaining why people are hearing different things.
The viral tweet posted by Feldman was actually taken from a post on Reddit, as she has explained. And the person who appears to be the original Reddit poster, RolandCamry, says that he made it from playing a recording from Vocabulary.com out of his speakers. In other words, there are multiple steps that degrade the quality of the audio.
(Spoiler alert: Based on what the Redditor who claims to be the original poster said, the original recording is probably this one on Vocabulary.com, which says “Laurel.”)
The poor quality of the audio, likely rerecorded multiple times, makes it more open to interpretation by the brain, says Brad Story, a professor of Speech, Language, and Hearing Sciences at The University of Arizona. Primary information that would be present in a high quality recording or in person is “weakened or attenuated,” Story says, even as the brain is eagerly looking for patterns to interpret.
“And if you throw things off a little bit, in terms of it being somewhat unnatural, then it is possible to fool that perceptual system and our interpretation of it,” says Story.
Story says the two words have similar patterns that could be easy to be confused. He carried out his own experiment by analyzing a waveform image of the viral recording and compared it to recordings of himself saying “laurel” and “yanny.”
He noticed similarities in the features of these words, which you can see below. Both words share a U-shaped pattern, though they correspond to different sets of frequencies that the vocal tract produces, Story explains. Take a look here:
Story analyzed the acoustic features of the words “Yanny” and “Laurel.”

“So with a recording that’s somewhat ambiguous and low-quality, it’s not surprising that some people may flip those when they’re perceiving that word,” Story says. That probably wouldn’t happen in a high-quality recording, he says, or if it were spoken in a full sentence to give people more context clues.
Britt Yazel, a neuroscience doctoral student at U.C. Davis, analyzed the sound file and filtered out all the sound above the frequency 4.5 kHz.
That filtering “takes away the entire perception of hearing the word ‘Yanny’ and all you get is the word ‘Laurel,'” he says. “If you lose the high frequencies, the illusion goes away.”
Some people have greater sensitivity to higher frequencies or lower frequencies, Yazel says, which could explain part of why people hear different things.
“But not only that, the brains themselves can be wired very differently to interpret speech,” he says. For example, if you hear the sounds in either “Yanny” or “Laurel” more in your everyday life, you might be more likely to hear them here.
It’s also worth noting that people are expecting to hear either “Yanny” or “Laurel,” which makes it more likely that they actually will hear one of those words and not something else.
For Kraus, the Northwestern professor who runs a laboratory on the biology of how humans process sound, it matters little how people interpret this single word in a poor-quality, idiosyncratic recording. Where this does matter, she says, and where similar issues are at play, is how people fill in the gaps of their hearing when faced with a noisy context. Much of what you hear, she says, is about what you’re expecting to hear.
She provides another example. First, listen to this noisy clip and see if you can hear a sentence.

Next, listen to this clip, which is no longer noisy.
Clear Clip
Finally, go back to the first clip. Now that the brain is primed to cut through the noise, you will probably be able to hear “The juice of lemons makes fine punch.”
“We all perceive the world a little differently based on our experiences,” she says. It’s crucial, she adds, to “use your experience with sound and what you know about it to fill in the gaps.”
Gdamn joos trying to gaslight people with BS like this. More infinitely malleable words to add to their “newspeak”.
Damn Jewish yannys..
Alright, come clean. Who here heard “Yanny?”
.
I am still hearing “laurel” but it wouldn’t surprise me to find they were beta testing the effectiveness of something else they have been introducing to people. Certainly not the first time we’ve been guinea pigs or rats.

Sounds more like “Yammy” (not “Yanny”) to me. I sure as hell don’t hear “Laurel”. However, since the answer is worthless regardless, who gives a rat’s backside?
I do. I want to understand why you heard “Yammy,” when I, and all others in my household heard “Laurel.” Now it could be “gaslighting” as Martist suggests, or a distraction for us to be preoccupied in, and we know it’s from NPR, so it’s already suspect, but I still want to know. I do know when people go for hearing tests, some hear frequencies that others do not. Maybe it has something to do with that.
Okay, back to geo-political atrocities.

I ain’t heard nothing. It could be because I ain’t listened and don’t care, or I’m just a deaf wheelchair bound psychopath.
distraction bullshit
who G A F ?
way way bigger issues going on ,, right here at home
instead of trying to figure out what your hearing on this useless distraction , try pushing back on the shit yer seeing daily
wanna know what I heard.. ?
I heard “round them up against the wall, lock and load”
