The sound of his own footsteps seemed very far away.

She looked up at the sound of footsteps outside the door.

He looked up from the fire at the sound of footsteps.

I heard the door open, and then the sound of footsteps.

As from far away, he heard the sound of footsteps.

One set of footsteps came all the way to the office.

The sound of footsteps brought him back to the present.

Where was the person who had made the sound of footsteps?
