What Does Sound Look Like?

What do you find interesting about this video? How does seeing sound visualized help you understand what sound is?

    Something that I find interesting about this video is the fact that sound itself is able to be visualized. Oftentimes, hearing, much like all the senses, is separated in an entirely unique category from the other senses. So to see how it can cross over and be sensed in a different way, i.e., through sight, is incredibly fascinating. Being able to see sound visualized helps me understand what sound is as it shows how it moves and, with the video especially, how it works fundamentally. The video explains how sound changes air density and can actually affect light, which is how it can be seen but also helps the viewer understand how it works.
