A person shouts inside a long tunnel and the shout rings on. They walk out the end of the tunnel and shout again into the open air, where the voice vanishes quickly.

Key standards

Visual physical commonsense (V-PC)

  • A person shouts inside a tunnel.
  • The same person walks fully out of the tunnel and shouts again in clearly open air.

Audio physical commonsense (A-PC)

  • The tunnel shout carries a sustained reverberation tail.
  • The open-air shout decays rapidly with negligible reverberation.

Cross-modal physical commonsense (AV-PC)

  • Each shout sound aligns in time with the person's visible shouting action.
  • The reverberation character of each shout matches the visible space in which it occurs.
