Are Echo and Reverberation?

Here's a quick explanation: An echo is a single reflection of a soundwave off a distance surface. Reverberation is the reflection of sound waves created by the superposition of such echoes. ... An echo is usually clear and can be easily distinguished because of the distance and time the sound wave travels.
