Meeting of a sound event and a sight event.
- Can be loose (can extend to Audiovisual dissociation if the temporal interval becomes consequent) or tight (provides more realness to the diegesis)
- If an event happening offscreen occur, an element onscreen needs to react in order to stay relevant
- Can underline point of audition (ex: if taken from the camera point, a sound happening far away should arrive slightly later than the visual impact, speed of light vs. speed of sound)
