Three years ago, the internet melted down over the color of a dress.
How can people hear one sound in two different ways? Is it "Yanny" or "Laurel"?
TMZ solved the debate, revealing the right answer was Laurel.
In addition to the A-10, she said Afghan A-29 ground attack aircraft and Russian-made Mi-17 helicopters contributed to beating off the attack, which reportedly resulted in heavy losses for the Taliban. Some people saw the dress as white and gold, while others saw it as black and blue. "N is similar to r; I is close to l". There is too much publicity now about what you should hear (why are there only 2 choices?) to back up and do an unbiased test.
Perplexed, she shared this with other students and the rest is history.
But if muddy audio or an unfamiliar speech pattern is all it takes to fool the brain, how can we trust anything we hear?
He said the acoustic information that makes us hear Yanny was higher frequency than the acoustic information that makes us hear Laurel.
While the experts theorized, online sleuths were hard at work manipulating the bass, pitch or volume.
Douglas Beck, an audiologist at Oticon, told National Geographic that there is a difference between hearing and listening. The frequencies for each sound are a little different from person to person and language to language. Sometimes, a listener hears "Laurel" first, and then "Yanny" later - from the same clip!
"Some people's hearing might be so good that they can start to detect the lower frequencies of Laurel and start to pick up on that, as well". The audio is the same, but people hear different things.
