Place this bell at the opening of a dark academy edit, before any dialogue or action begins, then follow it with the Dun Dun Dun Sound when the teacher or secret is revealed, keeping the bell as the call and the second sound as the payoff.
About this sound
This is a roughly seven-and-a-half-second bell sound under the name Baphomet Academy, a bell effect built around a resonant ringing tone. It feels ominous and theatrical, more like a summons to a dark, ceremonial classroom than an ordinary school bell, and it gives a scene an eerie, slightly unsettling edge.
