My own words echoed hollowly as that voice had not.

Yet, though that one word echoed hollowly, there was no trace of fear in it.

She could hear it echoing hollowly in the cold stone space.

The sound of his boots echoed hollowly off the high ceiling.

It echoed hollowly, as though he was in some sort of a big hall or arena.

My steps echoed hollowly as I climbed to the third floor.

The church was half empty, and every sound in it echoed hollowly.

Her voice echoed hollowly off the water from the high ceiling.

The sound of his footsteps echoed hollowly in the station.

The voice that came back to me out of the darkness echoed hollowly.
