The second that divides the world. Plka lid sly nco else than you

Laurel or Yanny? With this sound controversy, the American Socialist Party has been working for a week. The people are talking about the word, but the word is not the rest. And what do you hear? See with them how the illusion works and different words for different people. In the end, let’s tell you which answer is right.

When the illusion of blue-ernch / blo-zlatch at divided the world in 2015, we resisted for a long time, we did not write an explanatory article. So this time we took our time, but again you will have it with a complete explanation. With your help, let’s try to map who heard a word.

Laurel? Yanny? e netute at all, what is it about? In the Czech Republic, this sound illusion is not breaking records, but in the USA it has been on the front lines for several days (even Bl dm reacted to it). You don’t need to know anything else for the arrest, not the question: Hear the word Laurel (you lrl), or the word Yanny (ti jny)?

Depending on what zazen sound you are listening to, you may have heard either word or word. I can easily hear the sound of the hunter standing next to him, and he heard the sound of others. This makes the illusion look like the famous atm, where different people saw different colors when looking at the same photo.

See how you can hear different words:

Use the slider to set the recording offset by one octave in and out. People usually hear the word Yanny when the frequency sn (slider to the left), and the word Laurel when the frequency zv (slider to the right). Interaktivn widget: Marcel ulek

How is it mon? The brain wants to make life easier

The Laurel / Yanny recording can be described as a sound version of the famous optical illusion of the so-called Rubin’s voice. What do you see when you look at the picture?

Rubinova v

Rubinova vza – optical illusion

Someone saw the blue vzu. Others will immediately notice two people looking at each other from the profile. And you originally saw your body, especially the problem between the two states. The image contains information from which one can choose one or the other variant in the brain. And especially keep secret that you chose.

It is similar with the sound illusion of Laurel / Yanny. It contains more information and the brain can choose only one of them to base its experience. Let’s add that filtering information is not unusual for the brain. Our senses give us a lot of information every second of us and the brain has to choose only the ones that are unusual, unusual, surprising or critical. After all, he has to throw away so that we don’t go crazy from the avalanche.

Two words in one hand

I can only tell if someone can hear something other than you in the sound. Even if you play the sound a little bit.

To understand where both words are hidden in the stack, let’s look at a visual representation of the frequency spectrum:

Spectrogram nahr

Spektrogram nahrvky Laurel/Yanny

At first glance, don’t look out of this picture. If you start experimenting with listening to different frequencies in isolation, you will soon find that the word Yanny (phonetically yen, someone sounds like them) is bleeding at all frequencies, while at deep frequencies we can clearly hear the word Laurel (three lrl).

An analysis of the Laurel / Yanny sound shows that in the lower frequencies (green rectangle) we hear the word Laurel, while in the upper (red rectangle) we hear something like Yanny.

You can take a closer look at these contexts in our explanation in the video in.

Help us map the illusion

So let’s see where the two words are hiding in the sound. For the bag, someone hears the deep word Laurel and tells their brain only the word hiding in the frequencies.

You can answer the answers confidently in the speakers on which you attach the recording. For example, high-quality headphones can make bass more pronounced, the word Laurel may be emphasized, while the speaker of a mobile phone will have problems reproducing their frequencies and you will quickly hear the word Yanny, which sounds at frequencies above 1 kHz.

How far you are from the speaker plays a role. Again, this is related to the sound characteristics of zazen and the ability to reproduce different frequencies. The depth of the frequency (bass) can be heard from the length of the audible, so some people hear the word Laurel close, but from the long but the word Yanny.

Well, you say, the difference in speaker base is especially, but how come someone standing next to the vs, you hear Laurel and you hear Yanny? The answer to this is a different word for different people in the same world. Simplified by the fact that different people are used to subconsciously prefer different frequencies, for example, on the basis of where their brains are used to detecting e. and conversely.

If you want to test what this kind of party hears, listen to the following recordings. After shifting the frequency by pt pltnuslyte this kind of word. So if you hear Laurel on the original recording, try the recording and you will hear Yanny in particular.

The illusion was created by accident, it was also Bl dm

So far, we’ve talked about someone hearing a word, another kind, and we haven’t given judgments. However, this is not one of those relativistic postmodernist illusions, when it is not true on either side. On the contrary. The question that the word knows has a clear answer.

These illusions did not arise at all with the aim of creating an illusion. According to Wired magazine, the sound was created as a poor recording made by a telephone from a computer speaker. The original sound comes from the Vocabulary.com dictionary and illustrates the pronunciation of the English word laurel(In addition to the word Laurel being a noun, it also exists as a noun laurel, means vavn).

The student shared the call in a mid-round in Georgia, USA. When she loaded the laurel from the dictionary into the phone and played the recording, she heard Yanna’s word. I asked the club, and they couldn’t agree on which word on the tape, Katie Hetzelov said to Wired. She published the recording on her Instagram, from where she was born on Reddit and according to Twitter. Eventually she got to Blho’s house:

How does the original sound from the dictionary look like compared to the sound that circled the Internet as an ambiguous sound of illusion?

Srovn

A comparison of the original recordings from the Vocabulary.com website (left) and the low-quality recordings (right), which were delayed by its frequency and thus made the word stand out in all frequencies.

It is obvious that the poor quality recording from the poor quality speaker cut off the high and completely delayed the bass. Listen to the original sound from the dictionary and then the sound is distorted by the recording:

Also be right in this case to those who heard the word Laurel. On the contrary, the word Yanny does not appear in the original recording (in the sense that no one spoke the word Yanny or anything like that into the microphone). It is an abbreviation of art at all frequencies, which coincidentally forms clusters (formants), which some people know as a word.

I was surprised that there is something that I can see unequivocally, someone in it completely different. Generally, this is because the brain processes perceptions to the basis of its settings.

This is true not only for sound and optical illusions, but also for much more complex problems. We often make the first impression there as well. And once we are convinced of it, it is very important to change our view, despite the facts. Therefore, it pays to remember how these illusions work and that different people perceive the world differently.

What do you hear?! Yanny or Laurel https://t.co/jvHhCbMc8I

Update: We have added an explanation of the frequency to the link. We explained the origin of the recording. We have added an interactive tool for testing different frequencies.

Did you hear Laurel or Yanny in the original video?
