Ship horns have long been used at sea as loud signals for arrival, departure and low visibility, and recordings of them became common stock sound effects for film, television and online video. Because the sound is instantly recognisable even without a picture, editors reuse it far beyond maritime scenes, turning it into shorthand for size, arrival and comic overstatement. On soundboards it sits alongside other loud effects such as an air horn, and its short length makes it easy to drop into reaction clips, gaming highlights and travel edits without breaking the pace.
