Question
What is the difference between echo and a reverberation?
Solution
Echo: An echo is formed when sound wave reflects and comes back after an interval ≥ 0.1s. Therefore in an echo, the original and reflected sound is heard separately.
Reverberation: It consists of successive reflections at intervals very small as compared to 0.1 second so that they cannot produce separate echoes.
Reverberation: It consists of successive reflections at intervals very small as compared to 0.1 second so that they cannot produce separate echoes.
