807.3 (E) (2) Physical Integration of Sounds
When sounds are present in an audiovisual work, they do not need to be physically integrated with the visual element in order to be considered “accompanying sounds.”
Most contemporary audiovisual works contain physically integrated sounds. For example, the soundtrack of a motion picture or the sounds of a videogame are considered integrated sounds. By contrast, sounds are considered non-physically integrated if the images and the sounds are fixed on separate objects, such as a filmstrip with a separate compact disc containing the narration that accompanies the still images.
