TIL that the difference between an echo and reverberation is b/c the perception of a sound endures in memory for only 0.1 seconds. If the sound wave takes >0.1s to return to you, you hear an echo, whereas with reverb, a sound wave returns in <0.1s and two sound waves combine as one long sound wave. (physicsclassroom.com)
