Sound waves that are reflected off of a surface and returned to the listener produce an echo. The listener hears it sometime after the direct sound because it is the reflection of sound.
An echo is a distinct sound wave that is reflected from a surface. For example, the echo principle is used in echo sounders to determine the depth of a sea or the location of the shoals of fish. A delayed reflection of sound arrives at the listener after the direct sound. A true echo is a single reflection of the source of the sound.
