First heard when Doctor Who began in 1963, the TARDIS landing noise became one of British television's most recognisable sounds. Created at the BBC Radiophonic Workshop for the show's time-travelling police box, its wheezing groan was designed to suggest a machine straining between dimensions rather than a conventional engine. As Doctor Who returned in 2005 and clips spread through fan videos, memes and short-form edits, the sound kept its place as instant shorthand for arrival, time travel and unexpected entrances.
