2.   She walked through the large hall, her footsteps echoing off the stone-flagged floor, but then she suddenly stopped.

3.   Our footsteps echoed as though there were other people walking to meet us from the far end.

4.   His footsteps echoed as he left.

5.   The air seemed dank and strangely chill, and her footsteps echoed eerily in the silence.

6.   Footsteps echo in the hallway.

7.   My lone footsteps echoed through the near-empty terminal building as I set out for operations, a quarter of a mile down the vacant corridor.

8.   Your footsteps echo.

9.   Then he walked away, preparing to show off yet another unused meeting room, his footsteps echoing in the empty corridor.
