Do You Hear “Yanny” or “Laurel”? The Scientific Explanation Behind the Viral Audio Illusion

The internet was taken by storm with an audio clip that divided millions: does it say “Yanny” or “Laurel”? The phenomenon became a global topic of debate, igniting conversations across social media, news outlets, and even family gatherings. The YouTube video “Do You Hear ‘Yanny’ or ‘Laurel’? (SOLVED with SCIENCE)” aimed to break down this auditory puzzle once and for all. 

What Is the “Yanny vs Laurel” Audio Illusion?

At its core, the viral audio clip is an example of an auditory illusion — a sound recording that can be perceived in more than one way. Some listeners clearly hear “Yanny,” while others hear “Laurel,” with neither group technically wrong. What you hear depends largely on how your brain processes sound frequencies. 

This phenomenon first exploded online in May 2018, after a short recording of speech was circulated on social platforms. A Twitter poll at the time showed that while about 53% of participants heard “Laurel,” nearly 47% reported hearing “Yanny.” 

Why Do People Hear Different Words?

The key reason for the split in perception lies in sound frequency and human hearing range:

Low Frequencies: More bass-oriented listeners tend to hear “Laurel.”

High Frequencies: Higher pitched elements make “Yanny” more prominent to others.

When the same recording contains overlapping sound frequencies, the brain emphasizes different parts of the audio spectrum — so one person might focus on lower harmonics while another focuses on higher ones. Essentially, both words exist within the sound file; how you interpret them depends on your auditory system and playback equipment. 

The Role of Audio Equipment and Hearing Ability

Your device’s speakers or headphones also influence which word you perceive. Lower-quality speakers may dampen higher frequencies, reinforcing “Laurel,” whereas headphones with brighter high-end response can bring the sharper tones forward — leading listeners to hear “Yanny.” This suggests the same clip may sound different across devices. 

Likewise, age and individual hearing ability can affect perception. Older adults often have reduced sensitivity to higher frequencies, making “Laurel” more audible. In contrast, younger listeners with better high-frequency hearing might be more inclined to perceive “Yanny.” 

A Scientific Lens: Perception and Ambiguity

This viral audio closely resembles other cognitive illusions —such as the famous blue-black vs. white-gold dress  where sensory ambiguity leads to differing interpretations among viewers or listeners.

Auditory experts liken the experience to a “perceptual boundary,” where multiple interpretations are equally plausible. The brain fills in gaps based on sensory expectations, frequency emphasis, and context. 

The Takeaway: There’s No Single Right Answer

Whether you hear “Yanny” or “Laurel,” the debate highlights how human perception is shaped by neurology, hearing range, and audio context. The viral clip doesn’t trick one group into “hearing it wrong”  it simply illustrates that the human brain doesn’t always interpret sensory information uniformly.
