The audio clip was created by a speech and hearing professor named Brad Story. One video on Youtube.com garnered over 6 million viewers.

A recent Twitter poll found that 47% of the users hear "Yanny" while 53 percent hear "Laurel."

Individuals hear sound frequencies and acoustic features differently depending on the environment they're in or whether they are listening on a laptop, smartphone, or through headphones.
Younger people hear more higher frequencies than older people who lose some ability to pick up higher frequencies as we age. Younger people tend to hear "Yanny" (higher frequencies) while older people might hear "Laurel" (lower frequencies).
