Do you hear yanny or laurel?
A recent Twitter poll found, that 47% of people hear " yanny" , while 53% hear " laurel" .
Clearly this has created an internet argument that is dividing the nation.
So what is the science behind the madness?
One of the first aspects is priming. If you were to play this clip without providing the option of " yanny" or " laurel" , you may have heard neither of these words.
But by reading them, you're primed to hear one or the other.
Secondly when you speak you are producing sound waves, which propagate through the air.

Here is the depiction of him saying " laurel" .
You can see that the acoustic features are very similar.
