Question

distinguish between echo and reverberation

Answer 1

echo is reflecting of sound and reviberation is the heared sound due to repeated reflection

Answer 2

Echo is a single reflection of a sound wave off a surface. Reverberation is the sound or the pattern created by the superposition of such echoes.

2. An echo can be heard only when the distance between the source of sound and the reflecting body is  at least 17 m. A reverberation can occur when sound wave is reflected by a nearby wall also.

3. An echo is usually clear and can be clearly distinguished. A reverb is not a clear replica of the original sound sample.
4. An echo can be heard in open area and close spaces. Reverberation is usually experience in closed spaces with multiple reflecting objects.
