What Does Sound Look Like?

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

    What I found most interesting is that light and sound kind of go hand in hand in terms of their impact in the way it travels through waves. Another thing was the way you can use parabolic mirrors to see light and sound waves in the air, you can even see the way heat radiates off of things through this. Seeing this video helps me visualize sound because I can see the ripples and waves in which it travels in its directions.
