With some delving into the audio, there is a way to hear both, or maybe not. He said there's a simple, logical reason why some folks who listen to the viral recording hear "yanny" while others pick up "laurel".
"When there is more energy towards the mid and higher frequencies, people tend to hear "Yanny". Same works in reverse by cutting out the high frequencies with a Low Pass Filter.
Over on ABC, Live! host Jimmy Kimmel tried to bridge the divide between Laurel and Yanny partisans, joking, "Whether you hear Laurel or Yanny, one thing we can all agree on: Nothing has ever mattered less than this". How one hears it is similar to how people viewed a dress on the internet three years ago and raised questions of whether the mind and ear can be out of sync.
Does the pitch alter what you hear?
The Taliban attacked the town of Farah
The Taliban launched a coordinated assault on Farah shortly after midnight, and quickly overran checkpoints at the city's edge. The Taliban stormed the city in the early hours of Tuesday morning and were pushed back early Wednesday, said Salangi.
An audio snippet with just two syllables has ignited an internet meltdown, dividing social media users into staunchly opposed camps: do you hear "Yanny" or "Laurel?" He also appeared to post the poll on Reddit under the username RolandCamry. She said she heard laurel. "Is the person more of a high-pitched voice or a low-pitched voice?"
"Part of it involves the recording", said Brad Story, Professor of Speech, Language and Hearing at The University of Arizona. And just like rabidly binging a true crime podcast or following a Twitter meltdown, the rise of laurel-vs-yanni was a ride from wild start to its logically-explained conclusions. The different things we hear reminds us that our world, and ourselves, are far more unknown than we think.
The brain and ear together makes a quite a toolset, selectively listening and/or blocking what we hear.
