Every once in a while we come across a video that makes us see the world in a totally different way. Like this crazy powerful short, which reveals what it’s like to go through life seeing but not hearing. It's narrated by Rachel Kolb and based on her essay "Seeing at the Speed of Sound," which details her experience as a deaf person. You can try to read lips, but what happens when someone is not looking directly at you, the room is dark, or someone is mumbling? It’s not just lost in translation. It’s never understood.
