This sound is associated with Phasmophobia, the co-op ghost hunting horror game from Kinetic Games that became widely popular after its 2020 early access release. Players began sharing its scariest audio moments in compilations, livestream clips, and short-form edits centered on hunts and close escapes. The attack cue stuck around because it is recognizable even out of context: one burst of it tells viewers that a ghost encounter has started and that panic usually follows.
