The internet is a wild and weird place. We had the dress that no one could decide what color it really was, which tore families apart. Now, we have a GIF people can "hear".

If you don't know what a GIF is, according to Dictionary.com it is "a lossless format for image files that supports both animated and static images." Pretty much it is an animated image or a short video clip that is on a loop with no sound. Key phrase there is "no sound", yes there is NO SOUND in a GIF. Despite that, some people are claiming they can "hear" this GIF that has been making its way around social media.

Some people claim to "hear" a thud sound. Others hear a "boing" noise. 70% of people heard something when watching this GIF according to a Twitter poll.

Why are people "hearing" this GIF?

Some claim it is due to synesthesia. According to Melissa Lee Phillips from the University of Washington, "[synesthesia] is a condition in which one sense (for example, hearing) is simultaneously perceived as if by one or more additional senses such as sight. Another form of synesthesia joins objects such as letters, shapes, numbers or people's names with a sensory perception such as smell, color or flavor."

Many articles point you to a video by BBC which explains the McGurk Effect, which is an illusion where visual cues change how you hear a certain noise.

Are you falling to this illusion?
