Stylized version of the Laurel and Yanny situation: Diagram of spectrograms. “Laurel” has all 3 formants, but with most power in the low frequencies. “Yanny” has all 3 formants, but with most power in the high frequencies. “LaurelYanny” has both high and low power, but nothing in the middle. So you have to guess.
This is what is *really* going on with Laurel and Yanny – why your brain has to guess (without telling you)
