Key standards
Visual physical commonsense (V-PC)
- The rubber band is visibly flicked once while stretched taut between two pegs.
Audio physical commonsense (A-PC)
- The twang decays to silence almost immediately after onset, with negligible sustain.
- The sound has the crisp twang timbre of a plucked elastic band.
Cross-modal physical commonsense (AV-PC)
- The twang onset aligns temporally with the visible flick of the rubber band.
