Place it at the start of a horror sequence, then follow it with the Dun Dun Dun sound for the reveal and the Bell Ding sound as a second cue before the next scare.
About this sound
This 13-second clip is a slow, ringing bell with a hollow metallic tone that hangs in the air. It feels uneasy and tense, like something is about to happen just out of sight, and it works best when the silence around it does the scaring.
