It's like the blue and black (or white and gold) dress once again.

Look at this GIF of a tower that jumps and lands on the ground between two other towers as if it were jumping.

No sound, but do you hear a thud on the head when the pylon lands? Probably not alone.

The Twitter user @IAmHappyToast has been credited with creating the GIF, but the animation took off after another user, Lisa DeBruine, asked if someone with experience in visual perception could explain why You can "listen" to this GIF.

One reason why users can feel or hear this GIF? Christopher Fassnidge, a doctoral candidate in psychology from City, University of London, tells The Verge that it is synesthesia.

Illusion occurs when the senses cross in the brain, such as hearing and sight, said Fassnidge The Verge .

According to Psychology Today, synaesthesia is a neurological condition in which people experience "cross-responses to stimuli". In the case of this GIF, that dull and trembling noise that occurs when the pylon lands makes some spectators feel or hear it, even without sound.

Twitter user HappyToast showed it again in a later tweet, showing a similar version of the animation without the jolting effect. This time, it is probably harder to feel or hear something.

If you really like this GIF, Reddit has it covered. The website presents a section dedicated to "Noisy GIFs".
