The terms "closed captions" and "subtitles" are sometimes used interchangeably, but they’re actually designed for two different audiences. Subtitles offer a text alternative for spoken dialogue in video, while closed captions not only show text when someone's speaking, but also describe background noises and other audio cues that need describing.

In other words, subtitles are for viewers who can hear the audio, but need the dialogue provided in text form, whereas closed captions are for viewers who can't hear the audio at all and need a text description of everything that is audible in a video.

Meanwhile, subtitles for the Deaf or Hard of Hearing (SDH) combines both these features. SDH are intended for viewers who are both Deaf or Hard of Hearing and do not understand the language spoken in the video. So if a video is in another language that the viewer doesn't understand, SDH will translate the language while also including descriptions of other audible events.
