Another researcher who talked to the Verge suggested that because the file itself was so noisy, it could be that people are filling in the sounds they don't hear clearly with what they expect to hear.
David Monahan said the audio clip "was Yanny when I listened on my computer and Laurel on my phone..." We also all process external stimuli differently.
It has to do with the bass frequencies not being perceived as loud at lower volumes.
No, we're not saying that just because headphone and speaker reviews help pay the bills around here. If you play the recording at a frequency with more bass, you're probably more likely to hear "Laurel", while if the there is less bass, you'll hear "Yanny".
Maybe the great "Yanny or Laurel" debate of 2018 will see both of these names feature more prominently in next year's rankings. To some people, the word sounds like "yanny".
Chandrasekaran told The Verge that because the original recording is ambiguous - it's awful, remember? - your brain needs to fill what it thinks you should hear.
The audio illusion popped up on Reddit a few days ago.
Turnbull tweeted that some people tend to fill in those audio gaps using their brain, but others may not.
In the clip posted to Twitter, a robotic voice is heard saying a single word.
