An audio snippet with just two syllables has ignited an internet meltdown, dividing social media users into staunchly opposed camps: do you hear "Yanny" or "Laurel?" Others are paying attention to the high frequency tones, so they hear "Yanny".
Give it a listen.
A straw poll carried out among staff in AFP's Washington bureau counted 17 for Yanny, and 14 for Laurel. "If you lose the high frequencies, the illusion goes away".
In perhaps the most vexing element of the debate, the majority of listeners hear beyond doubt one of the two words, with few waffling between the two.
They said older adults tend to start losing their hearing at the higher frequency ranges.
"But not only that, the brains themselves can be wired very differently to interpret speech", he says. It is known that some sounds are audible only to people under 25. If you play the recording at a frequency with more bass, you're probably more likely to hear "Laurel", while if the there is less bass, you'll hear "Yanny".
I have no idea how anyone else can hear anything but "Laurel" - even when I heard a change in the bass level provided by another tweet.
Do your speakers have anything to do with what you hear? Amid the background noise, you're able to focus on what your dining partner is saying.
