Place it at the exact beat where a character should have noticed the warning, then follow it with a shocked reaction sound so the surprise lands after the alert. For a bigger prank, open with a quiet keyboard typing sound and let this clip interrupt it, then close with a short laugh.
このサウンドについて
This is a short three-second burst of sharp electronic signal tones, repeated in a steady pattern that feels urgent and attention-grabbing. It lands like a quick alert, clear and insistent without turning into a long alarm, and it works best when a scene needs an instant jolt. The clipped rhythm gives it a playful, prank-ready edge, making a quiet moment feel suddenly interrupted.
