A cousin to the Sting, the Scare Chord is a sudden, sharp sforzando of dissonance or sheer noise intended to make viewers jump clean out of their seats. The thing that separates it from a Cat Scare is that it's non-diegetic: nothing onscreen causes the noise; instead, it's added to the soundtrack as a way of eliciting a jolt in the audience, often preceded by a deliberate lull in both narrative and musical action.
