Yanni or Laurel?

My 10 year old grandaughter can hear both at the same time.  I’m going to start asking her to evaluation my A-B tweaks and upgrades to my system.

For the life of me,  I don't understand How Yanni could come from this.... 
I hear Laurel,   Not even a hint of sounding like Yanni.  

Laurel...…………… Laurel...…………….Laurel...………… 
Never changes

I just saw a news clip on TV that showed an audio analysis on a scope of the sound waves.  They suggested there is a high pitch Yanni and a lower pitch Laurel being pronounced at exactly the same time.  The audio analysis suggested that some people have their ears tuned to high pitch and some to low pitch, and that determines which name/voice they hear.

I heard Yanni and I prefer bright, trebly systems.

Who cares really?  I sang along to the Def Leopard Hysteria album for 20 years before finally using Google to figure out what the real lyrics were.
