Key standards
Visual physical commonsense (V-PC)
- A visible striker makes contact with the bell exactly once on the body of the bell.
Audio physical commonsense (A-PC)
- The deep ringing tone is a single sustained ring at roughly constant loudness from the strike onset through the end of the clip.
- The ring has the pure, deep timbre of a real large bell.
Cross-modal physical commonsense (AV-PC)
- The ringing tone onset aligns temporally with the visible strike of the bell.
