While the exact recording behind this clip is not documented, its name points to the Hino 500, a well-known series of medium and heavy-duty trucks, and to angin, the Indonesian word for air. That combination suggests a recording of the truck's pneumatic braking system, a sound familiar to drivers and truck enthusiasts. Short vehicle sounds like this circulate widely in editing libraries and social video, where a single recognisable hiss can instantly identify a large truck without showing one.
