The resolution has undoubtedly left many in complete shell shock. How could one be so certain of something so wrong?
From Business Insider:
“Speech perception and production depends heavily on an internal map of speech sounds,” Kothare said. “You learn this map while learning to speak as a toddler and also while hearing others speak on a day-to-day basis.”
If you mess with the frequencies in a recording, you can change what people hear — it’s similar to the way that our eyes can be tricked by an optical illusion.
The New York Times tried this on Wednesday and created an audio-switching tool for the recording.
It turns out that our brains can shift pretty easily between hearing “yanny” and “laurel” based just on how low or high the frequency of the recording is. Add to this all the cultural and linguistic ways we’ve been trained to hear certain vowels, and you have a perfect recipe for a little audio illusion.
