In somewhat of a disappointment to the many people who heard "Yanny" in the clip, the actual word recorded in the original clip is laurel, defined as a "wreath worn on the head, usually as a symbol for victory". "A - E, Laurel, ah and Yanny, aw, I don't know how you could confuse the ah, and the aw even if you have a significant hearing loss". "The interesting thing about the word Yanny is that the second frequency that our vocal track produces follows nearly the same path, in terms of what it looks like spectrographically, as Laurel".
"Part of it involves the recording", said Brad Story, Professor of Speech, Language and Hearing at The University of Arizona. With over 14,000 votes, "laurel" edged out "yanni" 61% to 39% in a poll conducted by @KFCRadio on Twitter, but the disagreements and conversations have continued well into the week.

The debate began on Reddit and expanded throughout social media.
RNZ Auckland staffers unanimously heard "Yanny" in the clip, however further investigations showed it was possible to hear both words depending on the type of headphones worn.
"It's partly because of different frequencies in the audio file", Goetz said.
The brain and ear together makes a quite a toolset, selectively listening and/or blocking what we hear.
