The Great Yanny vs. Laurel Aural War of 2018, Explained

It's rare for people to disagree on the internet, but no amount of civility could be spared when a "social media influencer" named Cloe Feldman posted a four-second sound clip on Twitter on May 15, 2018 and asked followers whether they heard a voice say "Yanny" or "Laurel."

Maybe you hear "Yanny." Maybe "Laurel." Proponents of either one recognize a very distinct word, which seems like some kind of aural magic trick. 

Popular Science asked several audiologists to help explain what’s going on. Brad Story, a professor of speech, language, and hearing sciences at the University of Arizona, performed a waveform analysis, which is already more effort directed at this than at the ransom calls for the Lindbergh baby. Story observed that the recording's waveform displays the acoustic features of the "l" and "r" sounds, offering reasonable proof that the voice is saying "Laurel." Whoever engineered the track seems to have layered a second, higher-frequency artifact over it—a frequency that sounds like "Yanny" to some people.

But why do listeners hear one name versus the other? We listen with our brains, and our brains tend to prioritize certain sounds over others. You might be focused on hearing your child talk, for example, over the din of a television. Because "Laurel" and "Yanny" are on different frequencies, some listeners are subconsciously favoring one over the other.

Audiologist Doug Johnson of Doug Johnson Productions provided further proof in his YouTube video analyzing the recording. By isolating each track, it's clear listeners can hear both "Yanny" and "Laurel."

A bigger mystery remains: Who conceived of this recording? It wasn't Feldman, who said she picked it up from a Reddit conversation. According to Wired, the answer is likely Georgia-based high school freshman Katie Hazel, who was looking up the word "laurel" on Vocabulary.com, had the site play it back, and was confused when she heard "Yanny" instead. She shared the discrepancy on Instagram, which was picked up by school senior Fernando Castro. From Castro's Instagram, it landed on Reddit. The original recording was performed for Vocabulary.com in 2007 by an unnamed opera singer and former cast member of the Broadway musical CATS.

Vocabulary.com isn't sure if the singer will come forward to claim their role in this fleeting internet sensation. In the meantime, the "Yanny" and "Laurel" camps continue to feud, mystified by the inability to hear what the other can. Musician Yanni is in the former group.

15 Mysterious Facts About Agatha Christie

With over 2 billion copies of her books in print, British novelist Agatha Christie (1890-1976) has kept countless readers up into the early morning hours. Occasionally, the mystery surrounding her personal life—including a high-profile disappearance in the 1920s—has rivaled the best of her fiction. Let's take a look at some of the verifiable details of the famed crime writer’s life and times.

1. Agatha Christie's mother was against her daughter learning to read.

Before becoming a bestselling novelist, Agatha Christie was in real danger of growing up an illiterate. Her mother was said to be against her daughter learning how to read until age 8 (Christie taught herself) and insisted on home-schooling the budding author. Mrs. Christie refused to let Agatha pursue any formal education until the age of 15, when her family dispatched her to a Paris finishing school.

2. Agatha Christie's first novel was written on a dare.

After an adolescence spent reading books and writing stories, Christie’s sister Madge dared her sibling to attack a novel-length project. Christie accepted the challenge and penned The Mysterious Affair at Styles, a mystery featuring a soldier on sick leave who finds himself embroiled in a poisoning at a friend’s estate. The novel, which featured Hercule Poirot, was rejected by six publishers before being printed in 1920.

3. Hercule Poirot was based on a real person.

The dapper Poirot, a mustachioed detective who took a gentleman's approach to crime-solving, might be Christie’s best-known creation. Christie was said to have been inspired when she caught sight of a Belgian man deboarding a bus in the early 1910s. He was reportedly a bit odd-looking, with a curious style of facial hair and a quizzical expression. His fictional counterpart's debut in The Mysterious Affair at Styles would be Poirot's first of more than 40 appearances.

4. Agatha Christie once disappeared for 10 days.

In 1926, Christie—who was already garnering a large and loyal fan base—left her home in London without a trace. It could’ve been the beginning of one of her sordid stories, particularly since her husband, Archie, had recently disclosed he had fallen in love with another woman and wanted a divorce. A police manhunt ensued, although it was unnecessary: Christie had simply driven out of town to a spa, possibly to get her mind off her tumultuous home life. The author made no mention of it in her later autobiography; some speculated it was a publicity stunt, while others believed the family's claim that she had experienced some kind of amnesic event.

5. Agatha Christie wasn't big on violence in her work.

While a murder is typically needed to set a murder mystery in motion, Christie’s preferred methodology for slaying her characters was poison: She had worked in a dispensary during wartime and had an intimate knowledge of pharmaceuticals. Rarely did her protagonists carry a gun; her two most famous detectives, Miss Marple and Hercule Poirot, were virtual pacifists.

6. Agatha Christie had an alias.

Not all of Christie’s work had a mortality rate. Beginning in 1930 and continuing through 1956, she wrote six romance novels under the pen name Mary Westmacott. The pseudonym was a construct of her middle name, Mary, with Westmacott being the surname of her relatives.

7. Agatha Christie loved surfing.

The image of Christie as a matronly author of mystery is the one most easily recognized by readers, but there was a time when Christie could be found catching waves. Along with her husband, Archie, Christie went on a traveling spree in 1922, starting in South Africa and winding up in Honolulu. At each step, the couple got progressively more capable riding surfboards; some historians believe they may have even been the first British surfers to learn how to ride standing up.

8. Agatha Christie didn't like taking an author's photo.

Although not explicitly camera-shy—Christie took frequent photos while traveling—she appeared to dislike having her photo appear on the dust jackets of her novels and once insisted they be issued without a likeness attached. It’s likely Christie preferred not to be recognized in public.

9. Agatha Christie took an oath of detective writing.

Founded in 1928 by writer Anthony Berkeley, the London Detection Club, or Famous Detection Club, was a social assembly of the notable crime writers in England. Members “swore” (tongue mostly in cheek) to never keep vital clues from their readers and to never use entirely fictional poisons as a plot crutch. Christie was a member in good standing, and took on the role of honorary president in 1956 on one condition: She never wanted to give any speeches.

10. Agatha Christie tried her best to take up smoking.

While it would shortly gain a reputation for killing its devotees, smoking was once so revered that it seemed unusual not to take a puff. Shortly after the end of the first world war, Christie was quoted as saying she was disappointed she couldn’t seem to adopt the habit even though she had been trying.

11. Agatha Christie wrote a play that may never stop running.

The curtain was first raised on Mousetrap in London’s West End in 1952. More than 60 years later, it’s still being performed regularly and passed the 25,000 show mark in 2012. The play—about a group of people trapped in a snowbound cabin with a murderer among them—was originally a radio story, Three Blind Mice, that was written at the behest of Queen Mary in 1947.

12. Agatha Christie loved archaeology.

After divorcing alleged cad Archie, Christie married archaeologist Max Mallowan in 1930 and joined him for regular expeditions to Syria and Iraq. In 2015, HarperCollins published Come, Tell Me How You Live, the author’s long-forgotten 1946 memoir of her experiences traveling. Although she assisted her husband on digs, she never stopped working on her writing: Their preferred method of transport was frequently the Orient Express, a fact that likely inspired her Murder on the Orient Express.

13. At least one of Agatha Christie's fictional "victims" was inspired by a real-life nuisance.

When Mallowan married Christie, he was assistant to renowned archaeologist Sir Leonard Woolley. This fact upset Woolley’s wife, who refused to let Christie stay in a Mesopotamia digging camp; Mallowan was forced to take a train into Baghdad every night to see her. Christie soon wrote Murder in Mesopotamia: The victim was the wife of an archaeology field director who was bludgeoned with an antique mace. Christie dedicated the book to the Woolleys, who never joined Mallowan on an expedition again.

14. You can rent Agatha Christie's old home.

If you feel like inhabiting the same real estate as Christie is a bucket-list travel opportunity, her former home in Devonshire, England is available for rent. The centuries-old home was Christie’s summer getaway in the 1950s; portions of it are rented out to individuals or groups for $500 a night. Some furniture and a piano that once belonged to the author remain in residence.

15. The New York Times ran an obituary for Hercule Poirot when he "died."

Like Arthur Conan Doyle before her, Christie eventually grew tired of her trademark character and set about having Hercule Poirot perish in the 1975 novel Curtain. The reaction to his demise was so fierce that The New York Times published a front-page “obituary” for the character on August 6. Christie died the following year.
