IF you have spent any time at all on social media today, you'll no doubt have spotted at least one status or tweet from someone announcing they're 'Team Yanny' or 'Laurel all the way'. 

But why?

It's been described as a Magic Eye for the ears or the 2018 'Is this a white and gold or blue and black dress?' debacle. 

The latest confusion all started with a simple tweet asking what people could hear - Yanny or Laurel?

It seems the debate has split households, offices and friends this morning as people argue over what they can hear. 

But why are some people hearing something different?

A number of experts have taken to Twitter to explain it but the simple version is that this 'ear illusion' is the result of 'Yanny' being clearer in higher frequencies and 'Laurel' is clearer in low frequencies.

And playing with your stereo or speaker settings could mean you hear something different.
