What do you hear?! Yanny or Laurel pic.twitter.com/jvHhCbMc8I

I hear both at the same time. Not sure how anyone can hear anything else, but they obviously do. I suspect my perception is partially because I used to spend long, long hours (before the internet) decoding nearly incomprehensible song lyrics of obscure 90s bands.
The sounds of “Yanny” and “Laurel” are overlaid at different pitches, like many songs’ vocal tracks. I also have wide attention, so these sorts of things rarely have the intended effect.
