This is why you can hear this 'silent GIF'When a pylon jumps in a field, does it make a sound? Twitter user @IAmHappyToast has been credited with creating the GIF, but the animation took off after another user, Lisa DeBruine, asked whether any one with expertise in visual perception could explain why you can "hear" this GIF. Does anyone in visual perception know why you can hear this gif? pic.twitter.com/mcT22Lzfkp — Lisa DeBruine 🏳️‍🌈 (@lisadebruine) December 2, 2017One reason users might be able to feel or hear this GIF? In the case of this GIF, that thud and shaking that happens when the pylon lands triggers some viewers to feel or hear it, even without sound.
