Are you one of those baffled internet users as you hear something from this supposedly silent animation? Well, worry not for there's a scientific explanation for that. TLDR? You got tricked!
As you can see above, the mind-bending Gif shows a huge electricity pylon jumping over power lines, shaking the screen as it lands. This soundless Gif was first shared in Twitter and has left users baffled as they hear a mysterious 'thudding' noise each time the pylon lands.
Dr Lisa DeBruine, a psychologist at the University of Glasgow, posted the animation, asking: 'Does anyone in visual perception know why you can hear this gif?' She even added a poll on what people have experienced as they watch the Gif. The top vote? You guessed it right, the "thudding sound" with 75 per cent or around 15,000 people!
On the other hand, fourteen per cent or under 3,000 in total said they heard no sound at all while the other 20,000 claimed they heard 'something else'. The remainder of those who answered the poll, around 1,400, remained neutral.
Now EVERYBODY'S ASKING WHY? What's with this strange post that left people divided?
Dr DeBruine suggested that this may be due to what's called the ear's 'acoustic reflex'. Amazing as our brains are, simple illusions can still trick them.
Twitter user Mr Punkin wrote: 'I think you can [hear] it because the visual expresses an implied wave, which your hearing system anticipates and prepares for so the potential sound doesn't deafening you. The ear basically squints like an eye.'
Dr DeBruine tweeted in response: 'That's my perceptual experience, too. I can 'squint' my ears voluntarily and it's a similar feeling.'
"The acoustic reflex is an involuntary muscle contraction in the ear when we speak or hear loud noises. Muscles pull tightly within the 'middle ear' to protect the delicate machinery of the inner ear from being damaged. The reflex is mostly used against deeper, low-frequency sounds, such as the noise from a massive object colliding with the floor," Dailymail.com reported.
Experts explained that this weird thud is the reflex's sound as we anticipate a supposedly loud noise. Others also suggested that this may be due to our sight's association to a loud thud and since there's no sound at all, our brains try to make up and generate the noise for us instead, an 'auditory illusion'.
