I intentionally stayed away from the "Laurel/Yanny" stories because the story itself seemed frivolous.
When I finally heard the now-famous repetition, I was surprised that it wasn't even a close call. [I clearly hear "Laurel."]
But then the story becomes far more interesting. How could people hear such different versions? And in what other areas might similar differences occur?
Vox has the sound and gives an explanation.
