PAS
PAS or Potentially Audible Set
PAS is a kind of bounding-box for Player or NPC AI sound detection. [Clarify] It is measured as the set visleaves which are audible from the visleaf occupied by the Sensing NPC or Player. [Clarify] Similar to PVS, A PAS-test is only the first filter that a sound must pass in order to be audible to the NPC[Clarify]. An areaportal can be used to toggle whether a visleaf is part of the PAS.
