Key standards
Visual physical commonsense (V-PC)
- An airflow source is visible or clearly implied, and the plastic sheet shows rapid vibration driven by that airflow as a loose flexible film.
Audio physical commonsense (A-PC)
- The sound is a light, irregular, crackly fluttering timbre consistent with thin plastic film vibrating rapidly.
Cross-modal physical commonsense (AV-PC)
- The fluttering sound is continuously present while the plastic sheet is visibly vibrating.
