Key standards
Visual physical commonsense (V-PC)
- The tuning fork is visibly struck twice, first gently and then with clearly more force.
- The instrument is a recognizable tuning fork with two parallel prongs joined at a handle.
Audio physical commonsense (A-PC)
- The second ring is noticeably louder than the first ring while holding the same pitch.
- Each strike has the characteristic sustained bright metallic ring of a real tuning fork.
Cross-modal physical commonsense (AV-PC)
- Each ring onset aligns in time with a visible strike of the tuning fork.
- The louder ring corresponds to the harder strike.
- The quieter ring corresponds to the gentler strike.
