Yanny or Laurel?

Too awesome, I was thinking the same thing!

This has been the best explanation I’ve seen so far (Laurel is at a lower freq):https://twitter.com/mboffin/status/996562598815416321?s=21 …

Cool. But the "experiment" they are running doesn't take into account what kind of speakers are used for each listener. Speakers affect the mix of frequencies, which will also shift critical points. It will be hard to draw meaningful inferences from their data without this info.

I went from hearing Yanny to hearing Laurel. I noticed a pitch change as it did so. Those who hear Yanny are focusing on the higher frequencies, those who hear Laurel on the lower ones. Case closed.

I just tried this and I never hear Yanni. I scroll all the way to the edge and year Yalies. Is this my penance for going to Vassar?

Turns out it's not just sound, but all of our perceptions can be similarly fooled based on ambiguous data. It frequently comes up in the fields of pain perception and paradigm shifts. https://alifeofmovement.com/2018/03/11/captain-of-the-nervous-ship/ …

How brain deciphers sounds is also playing a role here. If you move slowly, you are likely to keep hearing the same word further into the spectrum. At the same point in the spectrum, you can hear either laurel or yanny depending on how fast/from which direction you reached there.

I heard "Yorrel". What does THAT mean?

At first, I could only hear Laurel. When I slided like three bars to the right, I started to hear "Yanny". Now I can also hear "Yanny" in the background when I listen to the original, but only as an "alien whisper" without a tone. Yanny-hearers perceive Laurel the other way round
-
Just like very cold and very hot temperatures feel the same, it is probably sth about the "calibration" of our hearing. Wenn we hear very low/high frequencies, we do not perceive them as "tonal" anymore, so our brain puts them into the background.

So what I got from that is I was right about it saying laurel and my wife was wrong.

I had a very unusual effect when playing with the slider. I found an equilibrium in which I could simultaneously perceive both "Yanny" and "Laurel". I was an almost indescribable effect, it was not hearing two separate sounds overlayed, or a morph of both sounds.

It still doesn't work for me even when cranked all the way to "Laurel"!

It sounds never like "Yanny" but rather like Yelly.

I think this is a possible explanation. As you age (especially western males) you lose the ability to hear higher frequencies. (I've heard some hypothesize that speakers of tonal languages do not lose these abilities.) https://www.google.ca/search?q=How+old+is+your+ear%3F&oq=How+old+is+your+ear%3F+&aqs=chrome..69i57j0l3.11921j0j1&sourceid=chrome&ie=UTF-8 …

Thank you for sharing! I teach High School and my students spent 30 minutes arguing about this in class yesterday so I look forward to showing them this!

We perceive different vowels for a number of reasons. What we expect to hear is a big part of it. Acoustically, overtone content is the actual difference between vowels. If your brain focuses on certain over tones, you'll perceive it differently than if you focus on others.
-
Usually our brain can sort the overtones subconsciously based on what we expect to hear and what it can make sense of based on the meaning we've come to associate with different sounds In this case, for whatever reason, people are hearing one or both of two common interpetations
-
Depending on the speakers playing the clip and how they reproduce different frequency bands, the overall and relative volumes of different overtones will make one or the other seem to stand out to different people.
-
Once you hear both and know how they relate, you can basically willfully choose which you hear, or in some cases, hear both simultaneously. It's kindof like an audio version of those illusions that could be an old or young woman, faces or a vase, etc.
