Key standards

Visual physical commonsense (V-PC)

  • A person walks from a busy outdoor city street through a heavy door and remains inside a building lobby.
  • The heavy door visibly closes behind the person to seal off the interior.

Audio physical commonsense (A-PC)

  • Loud broadband city street noise is clearly audible while the person is outdoors.
  • After the door closes, the noise drops to a faint muffled hum with reduced high-frequency content.
  • The reduced sound level is sustained while the person is inside the lobby.

Cross-modal physical commonsense (AV-PC)

  • The drop in street noise loudness and brightness aligns in time with the visible closing of the heavy door behind the person.
