Key standards

Visual physical commonsense (V-PC)

  • A scene inside a packed stadium is shown, and a separate exterior scene shows a parking lot with cars visible.

Audio physical commonsense (A-PC)

  • In the parking-lot scene the sharp clapping and whistles are noticeably attenuated while a low-frequency muffled crowd wash carries through.

Cross-modal physical commonsense (AV-PC)

  • The audible spectral character of the crowd matches the visible interior or exterior vantage of each scene.
