What happens when you start at the far left, then move gradually rightwards? I find that my brain's interpretation is quite sticky -- I can hear Yanny quite far to the left, and Laurel quite far to the right, depending on where I begin.
Glad to know I'm not alone. I feel as though I've probably abused my ears over the years with headphones and concerts. Plus I've had several experiences where I haven't heard high frequences that were unmistakable to others.
So I end up interpreting the Yanny/Laurel thing through the lens of a pre-existing anxiety regarding hearing loss. I have no idea if that's actually the right way to think of it, but nevertheless it's where my mind goes instinctually.
try different speakers.....when I first heard it I was wearing headphones, so I unplugged to play on speakers, and it suddenly swapped. So it's not just about your ears
So I just tried it on all my devices - PC speaker, Bookshelf speakers, MBP speakers, iPhoneSpealers, Airpods, Earpods, and IEMs - still only hear laurel and gailey/yailie.
To me the "Laurel" just gets more and more distorted, and I start to hear a faint squeaky yerry... yerry... yerry on top of it. But it sounds more like an artifact than like a separate voice. I have no idea how it sounds like Yanni to anyone, but maybe I've lost my ability to hear high frequencies with age. (40m)
Crazy thought: Hearing loss starts at higher frequencies- so is it possible that we have a large portion of population with hearing issues due to years of abusing technology? (I.e. Loud music in headphones, cars, homes?)
Perhaps! I can't imagine living in a city, wearing headphones everyday, and hearing trains go by my apartment everyday is helping me hear "yanny" any better.
I've had documented hearing loss since I was a toddler and for the life of me, no matter _how_ hard I try, I just cannot hear yanny. I really wish I could hear it.
The effect is still mostly in your brain. It's not that people are completely death to such frequencies, just slightly less sensible. A small imbalance causes your perception to change 100%.
I'm a sound engineer and lifelong 'digital audio hater' who's objected to the unpleasant highs off CDs etc, relative to analog recording, for years. Also sleep in, and frequently use, earplugs, and live in mostly silence, also for years.
Almost impossible for me to hear 'Laurel'. It's Yanny all day, over here.
The BART is damaging thousands of people's hearing every day and nobody seems to care.
>long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sound, the shorter the amount of time it takes for NIHL to happen.
We were convinced for months before my friends and I got our hands on a decent decibel reader (didn't trust the phone apps) and it strays well past 85 up to 95 even, for up to 20-30 seconds between stops.
If you ever see a group of nerds with earplugs in our ears shouting at each other on BART, that's my friends and I, we carry extra individually packed earplugs, feel free to ask us for a pair.
30 seconds isn't nearly long enough for 95 a decibel noise to permanently hurt your ears. Even at 100dB permanent damage take on the order of minutes, not seconds. At 90 dB it's measured in hours. Your BART ride isn't hurting you.
The OSHA standards are a good starting point. Factory workers aren't even required to wear ear protection if the average noise over their 8 hour shift is under 85 dB. For 95 dB it's something like 15 minutes. From what I understand (and from what I've experienced), the every day repetition isn't the issue, it's the sustained noise for long periods of time. 2 little noisy bursts a day that are hours apart just aren't going to affect anything.
When people are playing music in their earphones, loud enough that you can hear it, while sitting next to them on the bus, they are absolutely damaging their hearing.
And I'm not even talking about big headphones, which do tend to leak a lot of sound, I'm talking about the little earbuds. The sound level in their ears must be off the charts.
I was firmly Yanny for the longest time, but now I'm hearing Laurel "by default" now. But I can easily hear both throughout most of the slider. In the middle it sounds like two people talking over each other.
Aside, this whole Yanny vs Laurel quarrel exposes a good example of how humans seem to approach opposing views in general.
The video sparks thousands of comments on Reddit and Facebook, many of them amounting to "I hear <X> and the rest of you are wrong!" -- surely in jest most of the time.
You have to wonder what fraction of people have the healthy response of "I hear <X> but I want to try to hear <Y> like other people, interesting."
Imagine if this was human nature, instead: "I hate Javascript, but I'd like to understand why someone would choose it on the server instead of assuming they are an amateur." HN would be much more relaxed. :)
Same with that blue vs gold dress "debate." -- Why is it a debate?
I don't mean to suck the fun out of it, though. But I do think it's a caricature of human nature in general.
Technology is very tribal I find. It seems like we have tendencies to make our technology seem as intimidating and alien as possible to signal to other tribes our superiority over them.
Generally our mental model of things and sounds is that they have one objective truth, the dress is either blue or gold, the voice is saying either laurel or yanny.
We often don't mind things that have a subjective element such as :- do you like tofu or not. We are prepared to tolerate the differences between people
Our biggest mistake is often to mistake ourselves as the golden sample of what the truth is, so normally, if this wasn't a viral thing exposing that people hear it differently, if we hear yanny, then it must be yanny, and how did these other people hear the wrong thing?
So it's good when we get gentle reminders that we need to question the truth of our perceptions and that it can be tricky to establish what the truth is.
To reiterate a comment I made yesterday, I used to have this viewpoint, that what we see and hear is objective, until I experimented with psychedelics, and my entire concept of reality was shattered.
Reality is objective, we can measure the spectrum of this audio clip, or the RGB values on the image of the dress. But the reality we experience is subjective, whether we hear laurel or yanny, whether the dress is blue or gold. What we see, what we hear, what we taste, it all gets subconsciously pre-processed before it reaches out conscious mind. To tie into another HN article from yesterday, an expensive bottle of wine does taste better to us, even if it's exactly the same wine inside. The objective reality is that it's the same wine, but our subjective reality, from what we see, from what we taste, is that the expensive bottle is a fine wine.
I've started to apply this realisation to life in general. If someone has a different viewpoint, I try to understand why they think that way, what has caused them to have that belief. So often in this day and age, people have a set opinion and think that if you disagree you're a bad person, or being deliberately wrong or lying.
As much as I hate to wade into the Trump debate and American politics, this has been one of the failures of the left in the USA. Instead of trying to understand why somebody might support Trump, instead of trying to view the world through a different lens, they just tried to demonise Trump supporters and convince everybody that if they voted for Trump they were bad people.
The political Right do exactly the same thing. Instead of trying to understand the viewpoint of the left, they accuse them of being socialists and hating America.
I was born and raised in deep Trump country, and have agree that most people don't take the time to understand the viewpoint of his supporters. Unfortunately, I also think that the deeper you dig, the more you realize it's an embrace of human selfishness. Trump doesn't have strongly held beliefs, he believes whatever -feels- right. You'll find a lot of overlap with Jordan Peterson supporters, and I'll leave you with a quote from one:
“Whenever I listen to him, it’s like he’s telling me something I already knew,” Mr. Logan says. “Learning is remembering.”
What makes "I hear <X> but I want to try to hear <Y> like other people, interesting." any more healthy than "I hear <X> and the rest of you are wrong!"?
It's certainly reasonable and "healthy" to confidently exclaim the latter. I'm quite confident in the fact that I heard "laurel" in the same way I'm confident that 2 + 2 = 4, and I truly believe any other answer to be wrong.
Now, the hearing test is presented in such a way that it would be "healthy" to assume there's more to it - that what you heard may be heard differently from others; this is an interesting yet unintuitive phenomenon. But, of course it's also healthy to assume the reverse. Maybe it's presented in a pseudo-phenomenological manner. Maybe it wants you to assume that some people hear the other word - a trick question. Maybe some people then would confidently and healthily exclaim that what they heard is correct, and no other answer is suitable.
Now, between "yanny" and "laurel", if you said you heard "lemon"...well maybe that's unhealthy - get your hearing checked.
2 + 2 = 4 is a pretty low-information statement: "4" has very little meaning other than "the symbol we assign to the value 2 + 2". 2 + 2 = 1 + 3 is a bit more interesting. 9 < π² < 10 is more interesting still, even though it is just as true as 2 + 2 = 4.
"I heard 'Laurel'" is also a very different statement from "The recording says 'Laurel.'" If you heard "Laurel," you heard "Laurel," nobody can tell you otherwise. But you might not have heard what was actually on the recording. Someone might have overdubbed a distorted version of "Yanny."
I don't know about healthy, but if my goal is the shared pursuit of knowledge and truth, someone who's able to meaningfully distinguish the ways in which they're confident of these various statements will be much more helpful to me than someone who does not. (Unless that person is a superhuman oracle who simply knows the truth of all things and does not need to reason about them, in which case, Lord, I am not worthy...)
2+2=4 is not just trivially true: Typically the symbol "4" is defined to be 3+1. (Actually it's defined as the successor of 3, but "successor" is essentially the same as "+1"). So 2+2=4 is exactly equivalent to 2+2=3+1. This is slightly different to your identity of 2+2=1+3, because 3+1=1+3 is also non trivial.
> But I do think it's a caricature of human nature in general.
The Earth is, after all, an organic computer, and humans are ideas with bodies, thrown into a contest of the fittest. Maybe the planet is just a single cosmic neuron, whose output will be the surviving ideas, weighted by how many humans support them.
I don't think you understand social interactions online very well...
People don't say it with a serious tone. It's mostly a friendly jab. It's similar to how people say "Chicago has the best deep dish and anyone who says otherwise is simply WRONG". The exaggeration is meant to be a joke
It's also very natural to act in this exaggerated way. Real resentment, subconscious bias and humorous exaggeration are influenced by the same mental model of us v. them.
I naturally joked that I would leave my SO since we're not hearing the same thing, and therefore can't possibly communicate well together; it was only in jest but I could feel this shape of segregation comes all too naturally and appeals to a deeper brain.
Some people are jokingly exaggerating and some people are being serious. I've heard people have arguments that became fairly angry about which pizza in town is the best. I've heard rather than participated in those arguments because it's laughable (and sometimes scary) when people don't understand the difference between subjectivity and objectivity. Some really do think their way of seeing the world is correct and anybody who varies from that is wrong.
There's another angle to this: people are way too sensitive. If they can't take honest negative feedback we'll end up with the current trend of everyone faking being nice to everyone else.
I'm happy the Internet lets us to be so honest and have a break from real life where no real argument takes place anymore because it has become bad social behavior.
Its not a good example actually. Im usually understanding, or at least try to, in professional environments, but when I’m with friends on replying to strangers on social media, it’s a different story. Especially when the topic in question is so irrelevant and insignificant. Is it going to hurt anyone’s feelings? Telling everyone that it’s one of the two and making a (silly) argument out of it is all fun and games at this point.
After playing with this, I can make my brain hear either — and even in rhythmic patterns (Yanny, Laurel, Yanny, Laurel, Yanny, Yanny, Yanny, Laurel). It’s a neat reminder of how much “preprocessing” our brains do before we experience a sound (filtering out what are perceived to be the irrelevant frequencies).
I think what's going on here is that the context of the sonic character of an individual's voice is crucial to the brain's processing of the phonetic content of utterances.
I spend my whole life listening critically to things. I was 100% YANNY on two sets of headphones and signal amplification paths. When I moved the slider bar about 1.5 notches to the left, LAUREL sort of "came into focus", and I felt like I grasped the human voice behind this severely distorted recording. Then, when I moved the slider back to the neutral position, I could not hear YANNY at all anymore. Only by taking a brief pause could I 'reset' my brain to hearing YANNY.
There's another processing step going on that helps us deal with distorted or band-limited voices. We're reconstructing in our heads the ideal sonic image of the human voice we're supposed to be hearing.
I hypothesize that if the sample in question came at the end of a few words by the speaker, not related semantically, e.g. "right, seven, purple, elephant, laurel", so the listener could reconstruct a more complete "imprint" of the speaker's voice in their mind, the YANNY outcome would drop to <1%.
I found three different "points" where my perception changes. The first is, when moving left to right one notch at a time, I hear it on change on the 9th notch (1-based numbering starting with LAUREL notch as 1). If I start from right to left, I hear it switch on the middle notch. And finally, if I leave it on the 8th notch, I can hear both ways at the same time and also 'force' myself to hear one or the other. Additionally, I can make it sound like "larry", "gary", "yally" and a bunch of other things on various notches without much effort, like all those 'ghost hunting' shows and their EVPs that sound like whatever the plot needs...
Are you talking about the McGurk effect? You hear either Ba or Fa depending on which you expect to hear based on the lip reading (but the sound that is actually playing is Va): https://youtu.be/G-lN8vWm3m0?t=77
It is really cool that small contextual information can change our senses so dramatically without us being aware of it happening.
I'm curious if there is an analogue for the black-blue/gold-white dress. I always saw it as black and blue (which it turned out to be), and held the consious beliefs that "this clearly is an overexposed photo" and "the black and blue color combo is something quite common while I've barely ever seen any gold and white clothing". I wonder if holding those beliefs can have an influence on the unconcious processing of the visual information.
Similarly, for this clip, Laurel is a name (and also otherwise a word) that I've heard quite a few times in my live, while I've never heard Yanny neither as a name nor a regular word.
20 years ago, I liked Yanni enough to see him in concert, maybe thats why I heard only Yanny for days (though I pronounce them differently). Once I heard Laurel, I haven't been able to hear Yanny since. I don't know what caused me not to be able to listen to Yanni anymore though.
Likewise. I had "Laurel" initially, but after going into "Yanny" territory, I can progressivley put the slider back to 100% "Laurel" and still hear "Yanny". Less so in the other direction.
Perception is about matching input to pre-conscious expectation. Once your brain has been primed to one word, you keep on hearing it when given an ambiguous signal.
Keyword: "priming", there's a lot of research on the topic.
I’m seriously curious about the voices of the individuals who initially heard yanny. I can hear either when I focus on different frequencies and timbre, but I first heard laurel. To me, that is the most pleasant to hear. Yanny on the other hand sounds like a combination of robotic and nasal which isn’t to my taste. Just wondering, does your voice lie in the spectrum of the bugs bunny sound?
As a male with a background in foreign languages, and who heard yanny first, I can confirm that my voice doesn't lie in the spectrum of bugs bunny :). But yes, the "yanny" variant does indeed sound like a malfunctioning robot, high-pitched and nasally.
Wow, so I listened to a clip the other night, and it was very distinctly laurel sound to me. This tool sounded like yanny, even with the slider all the way towards laurel, which I thought was confusing. Then I realized that I'm listening to this on my phone, and maybe the speaker not facing me and the sound rebounding off surrounding surfaces affected it. As I rotated the bottom of the phone, and thus the speaker towards my face, it started to sound much more like laurel to me. Cool.
This would be even more fitting, since it's about frequencies. If you blur your eye (removing the high frequencies) you see Marylin, otherwise Einstein.
Agreed. There is some of that for the young/old woman image, but it's clearer for Monroe vs Einstein. And it's even clearer in this video: https://youtu.be/tB5-JahAXfc
I'm reminded of what you would get (aside from a ruined needle) when you played some records backwards.
One example I remember: if you play the opening line of Madonna's "Like a Prayer" ("life is a mystery") it was supposed to sound like, "he will save us, Satan."
It's like pareidolia, but with sound. Once primed, you can hear whichever version you were primed with.
Another One Bites The Dust / it's Fun To Smoke Marijuana is a classic example, here's a nice mashup featuring a priest warning the world about it: https://www.youtube.com/watch?v=pdXek5d2ocw
The frequency response of the playback system probably plays a role here too. Try listening on headphones, on speaker, on laptop speaker, on in-car audio.
I feel like I'm alone on this so I'll speak up. I convincingly hear Larry. Are there any other claims or do people pretty much just claim to hear Yanny or Laurel?
Wow, I found it depends on which way I'm moving the slider. If starting from the left, I continue to hear laurel until right around the very right side. If I start on the right, and move it left, I start to hear yanny more and more. Even on positions where I was certain I heard laurel when coming left-to-right.
Yes, same here. BUt there is an obvious bias for one of the sounds. I can head yanny all the way to the left side if I step through it slowly. I can only hear laurel until 1/2 of the yanny side. A cool effect happened when getting at an "edge point" where I could hear both laurel AND yanny at the same time.
This one blows my mind. I must have replayed it two dozen times, trying to think of one word but to hear the other one. It just can't be done. There's no in-between, no fuzziness. When I think of "brainstorm", the word is unequivocally that. I even looked for "brain needle" or "green storm", but nope.
I had the same experience when using headphones. But then I showed it to my wife, through the crappy phone speakers, and she could only hear green needle, no matter what. And I... green storm. So quality matters too.
After listening to it a few dozen times, I'm fairly sure that it actually says Brainstorm and that "Green Needle" is an artifact of the awful speaker. There seems to be some sort of reverberation happening.
I can do "brain needle" or "green storm". Just like Yanny / Laurel, I believe the lower voice (brainstorm) is what is intended to be heard. The distortion artifacts in the higher frequencies just happen to match up with "green needle" - super interesting.
To me, the "Laurel" "Yanny" wasn't as interesting, because I could clearly hear both at the same time in different registers. But I really like this example because I can't hear "brainstorm" and "green needle" at the same time - it really seems like my brain shuts the other one off once I start listening to the audio.
This is great because I can hear both very easily while in can only hear Laurel moooost of the time. Here it's much clearer that when primed for "storm", "nee" is at most interpreted as a low deformed echo of "-ain", and when primed for "needle", the low sounds of "-rm" just disappear at the end. Thanks for the link.
I can't help but feel that there's an entity somewhere that's benefiting from this somehow.. Crowd-sourced machine learning training? The pessimist in me says that something spreading virally (globally) so rapidly must have some purpose behind it.
One of the most stunning illusions of perception I have ever witnessed.
Not feeling so loquacious just now but if you want to dig deeper the threads to pull are perception as bayesian inference and the sampling hypothesis. Olshausen and co are a good place to start.
It's well known that humans vividly hallucinate sounds - specifically overtones - that aren't really there; given specific sound (harmonic frequency) combinations.
It may be that how well you are able to "hear" (hallucinate) overtones is involved in this effect. Moving into the bathroom changed what I heard, and extra reflection of sound would alter overtone perception. I interpret that as (rather weak) evidence for the hypothesis.
I don't think we're hallucinating the overtones here - with an EQ (like in the link I believe) you can clearly separate the high and low freqs, and they sound like different words. So it's overtones baked into the audio file.
But what you're describing is exactly what you'd expect if you were dealing with overtones, actually - one tone of the two actual tones that create the illusion of the overtone has to be substantially lower than the other, always. If you knock out one tone by dumping some frequencies, the overtone vanishes, and those who were hearing it now hear something else. Those who never heard it, hear what they heard before.
The basic idea here is that if the harmonic match of the two fundamental (actual) tones isn't exact, then some listeners will hear the overtone, but less sensitive (or perhaps more refined) listeners' brains won't hear it. And many conditions will make it easier or harder for the listener's brain to (falsely but vividly) infer the overtone, including a lot of acoustic reflection (my bathroom example.) Completely knocking out one of the two fundamental tones will change what's heard by some - since now everyone will be hearing the same thing.
Similarly, shifting all frequencies up or down, even if all the information is preserved, can cause everyone to lose the overtone since the overtone is now at a frequency above (or below) what we can hear, so the brain doesn't hallucinate what is beyond it's capacity.
I found the balance point (a bit to the right of center) where I could merely think yanny or laurel to myself in a random sequence and I would hear the matching word 100% of the time.
I finally know what it feels like to have the power to change radio stations with my mind!

I suspect this has to do with frequency aliasing and high frequency hearing loss.
I find that if I move the slider while the sound is playing, or if I move the slider really slowly, my ears stick to the last word I heard.
Another thing is that the speakers matter. I can't hear Laural on my laptop, but I can hear it on my phone.
I've had documented hearing loss since I was a toddler and for the life of me, no matter _how_ hard I try, I just cannot hear yanny. I really wish I could hear it.

This effect very well might be just a side effect of humans' subconscious ability to focus on a single conversation in a noisy room.

This one is even more interesting for me: https://www.youtube.com/watch?v=5pRY3wlKwm8
If I think "Brainstorm" I hear that, but if I think "Green Needle" I hear that.
To me, the "Laurel" "Yanny" wasn't as interesting, because I could clearly hear both at the same time in different registers. But I really like this example because I can't hear "brainstorm" and "green needle" at the same time - it really seems like my brain shuts the other one off once I start listening to the audio.
Not feeling so loquacious just now but if you want to dig deeper the threads to pull are perception as bayesian inference and the sampling hypothesis. Olshausen and co are a good place to start.
It may be that how well you are able to "hear" (hallucinate) overtones is involved in this effect. Moving into the bathroom changed what I heard, and extra reflection of sound would alter overtone perception. I interpret that as (rather weak) evidence for the hypothesis.
The basic idea here is that if the harmonic match of the two fundamental (actual) tones isn't exact, then some listeners will hear the overtone, but less sensitive (or perhaps more refined) listeners' brains won't hear it. And many conditions will make it easier or harder for the listener's brain to (falsely but vividly) infer the overtone, including a lot of acoustic reflection (my bathroom example.) Completely knocking out one of the two fundamental tones will change what's heard by some - since now everyone will be hearing the same thing.
Similarly, shifting all frequencies up or down, even if all the information is preserved, can cause everyone to lose the overtone since the overtone is now at a frequency above (or below) what we can hear, so the brain doesn't hallucinate what is beyond it's capacity.
I found the balance point (a bit to the right of center) where I could merely think yanny or laurel to myself in a random sequence and I would hear the matching word 100% of the time.
I finally know what it feels like to have the power to change radio stations with my mind!
