If you thought sound looks like this, they you are wrong. Well, this is not sound by representation of sound being received or broadcasted by an electronic device. Surely, sound does not reach our ears like this. So what does sound look like?

Well, the good guys at NPR thought they will dwell into this further and decided to record visuals of sound.

Visual you say?

Yes, because, sound travels as waves, it should follow the actions we do and therefore using Schlieren flow visualisation bring us these visuals of sound! 

Hold your breath and watch the video!
