Airport chimes are a familiar part of public address systems in terminals around the world, where a short tone warns travellers that an announcement is coming. The sound has become shorthand for travel itself, so creators reuse it far beyond real airports, from holiday videos and airline-themed edits to comedy clips that mimic a boarding announcement. Its calm, recognisable pattern makes it easy to understand instantly, which is why it remains a popular choice for setting a location or signalling that news is about to follow.
