A car drives with the window open and city traffic is loud and detailed. The window rolls up and the noise immediately drops to a muffled hum.

Key standards

Visual physical commonsense (V-PC)

  • A car has at least one window starting open and visibly rolling fully up while the car is driving.
  • The camera is positioned inside the car interior to capture the experience of an occupant.

Audio physical commonsense (A-PC)

  • Loud broadband city traffic and road noise is clearly audible before the window is rolled up.
  • After the window is fully closed, the road noise drops to a muffled bass-heavy hum with reduced high-frequency content.
  • The reduced sound level is sustained while the window remains closed.

Cross-modal physical commonsense (AV-PC)

  • The drop in traffic loudness and brightness aligns in time with the visible rolling-up of the window.
