However, because basic subtitles assume that the viewers are not deaf or hard of hearing, they do not include other audio elements, such as music, sound effects, or speaker differentiation.

SDH is the most comprehensive type of subtitle or caption, including non-verbal sounds that contribute to the viewing experience.
