Put it at the exact beat where a trap is triggered, then follow it with the Danger Alarm Meme Sound to raise the stakes, and use Enemy Spotted just before it to warn viewers that trouble is coming.
Über diesen Sound
This is a very short electric spark, a sharp buzzing crackle lasting under half a second. It feels sudden and jolting, like a wire shorting out right beside you, and it works best as a quick shock rather than a sustained effect. The clip comes from Half-Life, where that kind of harsh electrical noise punctuates the game's tense, industrial world.
