Audio Description involves the accessibility of the visual images of theater, media, and museum exhibitions for people who are blind or have low vision. It is a free narration service that attempts to describe what the sighted person takes for granted—those theatrical images that a person who has low vision formerly could only experience through the whispered asides from a sighted companion.

In theaters, in museums, and accompanying film and video presentations, Audio Description is commentary and narration that guides the listener audience through the presentation with concise, objective descriptions of new scenes, settings, costumes, body language and “sight gags,” all slipped in between portions of dialogue or songs. It has been found to be not only a significant technique for making the arts more accessible for an important but underserved constituency—Audio Description can be viewed as an aesthetic advance for the visual and performing arts.
