A soft foam cushion is pressed down slowly, visibly deforming and rebounding; instead of muffled compression sounds, the audio emits dense stone grinding and crushing noises, as if rocks were pulverizing.

Sound: stone grinding and crushing noises

Key standards

Visual physical commonsense (V-PC)

  • A soft foam cushion is visibly pressed down slowly by a hand and visibly deforms and rebounds with continuous physically plausible elastic motion.
  • The cushion remains visibly intact soft foam throughout the clip, without breaking apart, fracturing, or revealing any hard rock material inside.

Audio physical commonsense (A-PC)

  • The audio is dense stone grinding and crushing with the harsh granular timbre of rocks being pulverized.

Cross-modal physical commonsense (AV-PC)

  • The stone-crushing noises are present in the audio while the foam cushion is visibly being compressed, aligning with the visible deformation.
