Younger people tend to be able to hear words spoken at a higher decibel, which means the older you are, the harder it may be to pick out the word "Yanny" as it is delivered in a higher pitch. I can't even figure out how one would hear Yanny", while Ellen DeGeneres wrote: "Literally everything at my show just stopped to see if people hear Laurel or Yanny.
Online search interest in Laurel is ahead of Yanny worldwide, according to Google Trends. So we want you to listen to it and decided what you hear. The problem is, much like "The Dress" debate in 2017, people are listening to the exact same recording and hearing two different words.
