That lines up with what Nina Kraus, a researcher at Northwestern University who studies auditory biology, told PopSci.
He said that is probably because at 52 his ears lack high frequency sensitivity, a natural result of aging, and secondly, a difference in pronunciation between the North American accented computer-generated Yanny and Laurel and how the words would naturally be spoken in Australian or British English.
This is a clear victory for Team Yanny but still doesn't answer the question of what the hell is going on here.
'Yup. That's all I hear too, ' another man agreed.
Your equipment (speakers, sound device, etc.) has a lot to do with it, as well.
Another smart idea someone shared was to record it on a different app, 'If you record it on Snapchat, there should be a chipmunk and bear sound effect on the bottom left.
The clip went hugely viral by Tuesday, with some saying they could even hear both and others claiming you can hear one on mobile and the other on desktop.
I personally tested it with my family, and sure enough, while I and a couple others heard "Laurel", the rest of the crew swore they were hearing "Yanny".
First, it was the color of a dress, now it's the word being said on an audio clip. Of more than 20 votes, 75 percent say it's "Laurel".
"When I analyzed the recording of Laurel, that third resonance is very high for the L. It drops for the R and then it rises again for the L", he said. Apparently it has to do with the pitch of the audio; yanny is in high pitch, while laurel is in low pitch. Once your brain has processed a sound as having a certain meaning, it is hard to hear it another way. Alais says that the brain can flip back and forth between both sounds because it can find a definitive interpretation of the clip. Younger people do tend to have better high frequency hearing.
