Striking the hour twelve times is the traditional way tower clocks and grandfather clocks announce midnight and noon, and that familiar pattern has made it a staple sound effect for editors. Online, the full twelve-chime version is popular because a single bell does not carry the same sense of occasion, so creators use it for New Year streams, haunted house videos, fairy-tale moments, and dramatic edits where time running out matters. Its slow, regular rhythm also makes it easy to sync to on-screen countdowns and scene changes.
