By Wednesday evening, it had more than 16.5 million views and the post had been retweeted more than 68,000 times.
Looking at the spectrogram, it seems to be somewhere between "Yanny" and "Laurel", so in a way, it is an ambiguous sound. "It is the Vocabulary.com audio", user RolandCamry said.
One sound clip is reportedly tearing the internet apart based exclusively on fighting surrounding whether, when played, the listener hears "Laurel" or "Yanny".
Dr. Nicole Rosen, an associate linguistics professor at the University of Manitoba, said she hears Laurel, but it depends mainly on the frequency people are hearing it.
By Monday night, the clip had spread to Twitter thanks in large part to vlogger Cloe Feldman, who tweeted it out to her more than 209,000 followers. What most people are listening to is a clip from Roland Szabo, a high school student in Georgia.
"How it was recorded, how it was played back, if there was any frequency modulation in between the two, and also the speaker, said Cavanaugh". The same physical sound is going into everyone's ears, but we hear completely different words.
The poor quality and different audio settings, headphones or speakers could cause someone hear either laurel or yanny. "We heard people say "Hear me", Dearie", "Laura" and "Yi-wee". In the original comment thread on Reddit, some listeners reported changing their minds after switching to a different computer. "I switched to my laptop and suddenly, all I could hear was a deep male voice saying, 'laurel'". First, audiologist Jessica Bell said " You know, you don't just hear with your ears, you hear with your brain".
