This 9.2-second effect is a sustained emergency siren, a high-pitched wail that rises and falls in a repeating cycle like a vehicle passing close by. It feels alarming and tense, instantly bracing listeners for danger or a chaotic reveal. The sound comes from real police cars, ambulances and fire trucks, not a single film or clip.
