An echo is the reflection of sound from the surface of an obstacle. Sound takes time to bounce off the obstacle and return to our ears, so we hear both the original sound and the echo.
When the original sound is reflected from walls and objects in an enclosed space, we hear a series of echoes. This is called reverberation. Cathedrals, gymnasiums and indoor swimming pools are good places to hear reverberation.
