A unusual audio clip has been igniting vigorous debate on the Internet - is the voice on the recording saying, "Yanny" or "Laurel"?
On Wednesday, after a daylong national debate, Wired found the high school students who first posted the audio clip.
"Yanni", he says with a chuckle, perhaps delighted that the viral phenomenon has greatly improved his Google rankings in the past few days.
The debate, which has been compared to a dispute over the colour of a dress in 2015, had some insisting they heard "Laurel".
"Laurel, and then I can hear Yanny as well", Tricia Grishaw, who works at Sal's said.
The recording seems to be a slightly altered version of Vocabulary.com's pronunciation aide for the word laurel.
Kami Rita Sherpa scales Mount Everest for record 22nd time
Nepalese mountaineer Lhakpa Sherpa prepares to leave for an expedition to Everest in Kathmandu on April 18, 2018. Kami Rita apparently hopes to reach 25 times before retiring.
"I hear yanny, but I listened to it this morning and I heard laurel", one woman said. Your brain is bound to pick out one word or the other given that prompt. "If you pay attention to the treble, the high frequencies or high pitches, you primarily hear Yanny", says Dr. Jace Wolfe with Hearts for Hearing. She said the complicated answer has to do with "resonance of the speech sounds".
"There really isn't a true reality, there is only our perceptual reality", Crum said. Even some doctors of audiology at Main Line Health are split.
Then, he said, you have to take into account the different ways people are listening to this - through mobile phones, headphones, tablets, etc.
Others heard different sounds on different equipment, while still others claimed to hear both.
The hairs take sounds we receive and turn them into messages for the brain.
Grr. The one that divided the worldover whether it was black and blue or white and gold? Oh.
