"When there is more energy towards the mid and higher frequencies, people tend to hear "Yanny".
The Tigers are just as divided over the question and can not come to an unanimous decision about what they are hearing. Some people are hearing "yanny", while others are hearing "laurel". "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.
Some people believe it's the difference in quality and the device you hear the sound on.
The fun (and frustration) of the clip is rooted in the fact that everyone seems to be split fairly evenly on the true nature of the sound.
People hear different words because the audio file has more than the usual number of frequencies. "Then there was a period where it sounded like someone was saying Yanny and someone else was saying Laurel at the same time". "That could have to do with your hearing or it could also have to do with what you're listening to it on. So whichever you're more dominant to is what you're going to lean to, and why you're so persistent on it, that's what you think you hear".
Story also said that, if you change the pitch of the original recording, you can hear both words.
But Cavanaugh still says no matter what you hear, you're not wrong or right if you hear one over the other. It's like it was put on the internet just to sow discord.
"It is possible that that recording is altered to make some of those sounds ambiguous and our brain is left to fill in the blank", Geddes said.
