reverberation

A minute later the street door, four flights down, rang out in jarring reverberation.

The air was calm, and the reverberation rolled far over the forest.

Just before dawn he was assisted in waking by the abnormal reverberation of familiar music.

They were like the reverberation of some far-off tutored circle.

Suddenly a voice boomed at them, like an echo, more than the reverberation that the cave would give.
