"For starters, what you hear depends on which frequencies your brain emphasizes," said Aronson. "In a noisy recording, there are lots of different frequencies captured. Higher frequency sounds in the recording make people hear Yanny, whereas lower frequencies cause others to hear Laurel."
Why is it different for some than others? Well, it has to do with your age, according to Aronson. "Older adults often start losing their hearing within the higher-frequency range, meaning it's possible that more young people hear Yanny."
Age isn't the only factor impacting audio—there are also other technical factors at play. "What you hear might have to do with your speakers, headphones, or the acoustics in the room," concluded Aronson. "There's also the question of what platform you heard the recording on first—the differences in the audio could have something to do with how Twitter or Instagram compresses video files."
"The Yanny versus Laurel kerfuffle is wonderful," added Margot Douaihy, writer, educator, and editor-at-large of AV Technology. "This debate reminds us that there is room for interpretation within the science of audio. There is so much we know and can measure, but hearing is a personal experience. Context matters."
What did you hear, #AVTweeps? For the record, I heard Yanny.
