This is What Sound Looks Like
Adam Cole is the science fanatic behind NPR’s popular science blog Skunk Bear. In a recent post, Cole wondered if he could use a technique known as Schlieren Flow Visualization to see sound.
The answer was a resounding YES! And the video below shows the fascinating results. Also included: a diagram of how Schlieren Flow Visualization works and animated gifs (from the video) that show what different sounds look like.
