Clicked on the Slider at mid-point and slowly slid it toward "Laurel" side - I continued to hear only Yanny until I reached the First division from the left and then I heard both. Thereafter I could hear both no matter where I placed the slider ~
In my instance I hear Yanny louder than Laurel - although on a discussion about this on a Talk Radio station at this moment some heard it the other way around . ?
