The internet has brought us another heated debate of the senses - not a picture this time, but an audio clip. So if a person hears lower frequencies better, "You would hear Laurel, because that has lower frequency sounds in it".
Hetzel said she heard "Yanny" instead of "Laurel" and told WIRED that she shared the clip with her friends and posted it on Instagram.
Since the clip went viral, the students responsible have solved the mystery - and the winners, it seems, are the "Laurel" team.
The US Department of Defense made light of the controversy on its Twitter account, with a photo of a US Marine Corps instructor berating a recruit: "I said it's #Yanny, recruit, not #Laurel!".
If Grimes and Elon Musk broke the internet, Yanny and Laurel are here to absolutely demolish the remains. "It is going to interpret three of them, and it can kind of pick which ones it decides to hear". "We have the suggestion of the two choices, Yanny or Laurel, and depending on our perception we respond accordingly".
It's not really a word, but it's not really a sound either; so many questions stem from two simple syllables.
Whichever word you hear in the recording, the speech scientists both say you shouldn't worry: "It's totally OK to hear what you are hearing", Kothare said. "If you lose the high frequencies, the illusion goes away".
Kimmel also created his own audio puzzle of listeners, enlisting correspondent Guillermo Rodriguez to say a word that has split his colleagues at Live! as to whether he's saying "yogurt" or "joker".
What do you hear?! We should probably all take a one month break from the internet. She adds that sound can be filtered with our expectations.
