Key standards

Visual physical commonsense (V-PC)

  • The drumstick makes visible contact with both a metal railing and a rubber mat at distinct points in the clip.

Audio physical commonsense (A-PC)

  • The metal-railing tap is a clear ringing metallic ping with sustain, and the rubber-mat tap is a distinctly dry dead thud with rapid decay.

Cross-modal physical commonsense (AV-PC)

  • Each tap sound coincides in time with a visible drumstick contact on its corresponding surface.
  • The ringing metallic ping with sustain corresponds to the drumstick contacting the metal railing.
  • The dry dead thud with rapid decay corresponds to the drumstick contacting the rubber mat.
