It's been labelled the new 'Dress' debate.
An audio recording has confused hundreds and divided friends and workmates - all because a recording says "Laurel." Or is it "Yanny"?
A recording posted onto Twitter has got the internet debating between the two names. But the secret into why people hear two different versions can be interpreted by the pitch of the audio.
According to a theory posted online, the audio illusion you hear can be dependant on the amount of bass you're listening to through your device.
Either way, we know Laurel is the right answer.
