Try The McGurk Effect! The McGurk effect is a compelling demonstration of how we all use visual speech information. The effect shows that we can't help but integrate visual speech into what we hear.

I still hear Yanny through the computer speakers.

I sort of recall being able to hear Laurel through headphones or different speakers a couple of years ago.
Perhaps whatever it was had a more recessed high frequency response.

Tritone Paradox.

The tritone paradox is an auditory illusion in which a sequentially played pair of Shepard tones separated by an interval of a tritone, or half octave, is heard as ascending by some people and as descending by others.

Different populations tend to favor one of a limited set of different spots around the chromatic circle as central to the set of "higher" tones. Roger Shepard in 1963 had argued that such tone pairs would be heard ambiguously as either ascending or descending.

However, psychology of music researcher Diana Deutsch in 1986 discovered that when the judgments of individual listeners were considered separately, their judgments depended on the positions of the tones along the chromatic circle.

For example, one listener would hear the tone pair C–F♯ as ascending and the tone pair G–C♯ as descending. Yet another listener would hear the tone pair C–F♯ as descending and the tone pair G–C♯ as ascending. Furthermore, the way these tone pairs were perceived varied depending on the listener's language or dialect.

Look into "otoacoustic emissions" Weird.. Evidently in some people the ears can actually produce sounds of their own.

[TheOctopus]

An otoacoustic emission (OAE) is a sound that is generated from within the inner ear. Having been predicted by Austrian astrophysicist Thomas Gold in 1948, its existence was first demonstrated experimentally by British physicist David Kemp in 1978,[1] and otoacoustic emissions have since been shown to arise through a number of different cellular and mechanical causes within the inner ear.[2][3] Studies have shown that OAEs disappear after the inner ear has been damaged, so OAEs are often used in the laboratory and the clinic as a measure of inner ear health.

Broadly speaking, there are two types of otoacoustic emissions: spontaneous otoacoustic emissions (SOAEs), which occur without external stimulation, and evoked otoacoustic emissions (EOAEs), which require an evoking stimulus.

I hear Laurel, everytime

I clearly heard Yanny once and then Laurel each and every time after. Can't go back to Yanny... It was very distinct and clear as day. If I had to swear on the Bible, I would have said Yanny after the first time... Except it is Laurel now. Just goes to show... But nearly half the people hear one over the other and it seems to be age dependent too. So much for the ears as an instrument of precision?

[CPP]

Laurel, each and every time.. Lets, see the world will not stop, the common cold will not be cured so it doesn't matter, at all..

[TheOctopus]

Pay attention to "Mysterious Melody" effect. That should really drive the point home about our "audio memory".

How can anyone claim they heard "something" and describe or compare it when it was completely different the second time around?

The McGurk effect validates what I have been thinking for a while.
You watch a YouTube music video and even though the audio might be compressed and low resolution, you don’t feel that way.
That’s because the video seems to have a higher hierarchy in our brain and shapes what we hear. And that is what I understand that the McGurk effect proves.
Take a lower resolution audio with good video resolution and you will enjoy it more than just audio alone.
Real life is audio and video together. Trying to get a full ‘picture’ out of just audio alone is not attainable.

I would say that I truly enjoyed Bluray concerts in the theater room. The combination of a high end 7.1 and a big screen with a projector was truly a treat for all the senses, including the chest and gut punching bass from the music. That's the one aspect I miss, the spectacular concerts.

My favorite line from the 1983 Matthew Broderick movie WarGames is ...

"A strange game. The only winning move is not to play. How about a nice game of chess?"

Laurel, every time from me

The explanation on video indicated that when high frequencies are filtered out one hears Laurel.
Does that mean that if someone hears Laurel is because that person’s hearing is deficient?

Wikipedia had these explanations to offer from the experts:

On May 16, 2018, a report in The New York Times noted a spectrogram analysis confirmed how the extra sounds for "yanny" can be graphed in the mixed re-recording.[3][18] The sounds also were simulated by combining syllables of the same Vocabulary.com voice saying the words "Yangtze" and "uncanny" as a mash-up of sounds which gave a similar spectrogram as the extra sounds graphed in the laurel re-recording.[3]

Benjamin Munson, a professor of audiology at the University of Minnesota, suggested that "Yanny" can be heard in higher frequencies while "Laurel" can be heard in lower frequencies.[1] Older people, whose ability to hear higher frequencies is more likely to have degraded, usually hear "Laurel". Kevin Franck, the director of audiology at the Boston hospital Massachusetts Eye and Ear says that the clip exists on a "perceptual boundary" and compared it to the Necker Cube illusion.[19] Professor David Alais from the University of Sydney's school of psychology also compared the clip to the Necker Cube or the face/vase illusion, calling it a "perceptually ambiguous stimulus".[15]

Brad Story, a professor of speech, language, and audiology at the University of Arizona said that the low quality of the recording creates ambiguity.[20] Dr. Hans Rutger Bosker, psycholinguist and phonetician at the Max Planck Institute for Psycholinguistics, showed that it is possible to make the same person hear the same audio clip differently by presenting it in different acoustic contexts: if one hears the ambiguous audio clip after a lead-in sentence without any high frequencies (>1000 Hz), this makes the higher frequencies in the following ambiguous audio clip stand out more, making people report "Yanny" where they previously maybe heard "Laurel".[21]

TL;DR summary: Old people hear Laurel.
