Sounds may be heard from GIF images that should be silent

byAudio-Technica

GIF animation is moving images by connecting them, and audio is not recorded anywhere in the file. However, sometimes I feel that "there is a GIF animation that can hear sound." This seems to be an "illusion" caused by visual information that the auditory information has been influenced.

An example is the following GIF animation. It is an image as if the steel tower is jumping rope with a transmission line.

Looking at this animation, it seems that 70% of people seem to hear the landing sound of the jumping tower. Of course, it's not just embedding a YouTube movie, it's just a GIF animation so the sound is not actually playing.

Still, many people responded "I hear the sound" because the GIF animation has "gimmicks to feel sounds" added. The following GIF animation is similarly a tower jumping rope, but sound should not be heard.

The difference between these two GIF animations is whether or not an oscillating effect is added when the tower lands.


Auditory information is affected by visual informationMcGurk effectIt is known as. In the case of the GIF animation of the tower, when looking at the image swaying with the vibration of the landing, I can not hear it saying, "When this sight is like this, it sounds like this" based on the experiences I have heard or heard in the past It sounds like a sound that should be heard.

As for the "illusion" of the ear, an example is cited as a movie called "Can You Trust Your Ears? (Audio Illusions)" by the scientific YouTube channel "AsapSCIENCE".

In addition, some people may feel not only sound but also even vibration. This is because the brain responds by predicting the events that occur first based on visual information.
