Didactic SDH can be defined as a pedagogical task where students get involved in a media accessibility practice by producing SDH for a preselected video extract. That is, students create SDH with the aim of making a short video extract accessible for someone with hearing impairments
or deafness. It should be noted that the video selected for didactic SDH should contain features that allow for the inclusion of the description of sounds, music, mood and other paralinguistic elements; cartoons are typically good options for didactic SDH, given the music, sounds and changing moods they tend to portray.
