Question

1) What is echo and reverberation ?​

Answer 1

Answer:

Echo echo is a reflection of sound that arrives at the listener with a delay after the direct sound.

A reverberation, or reverb, is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air
