Answer 1

What is Reverberation?

Answer :

The persistence of sound due to repeated reflection and its gradual fading away is called Reverberation of sound.

Since a concert hall is designed to reflect sound from multiple surfaces, the sound produced on stage arrives at the listener through different path.

since the sound waves travel on different paths, they take different amounts of time to reach the listener. If the waves of the same sound arrive after a distinct interval, the listener will find it disturbing. However, the same sound arriving in quick succession will appear to fade away in a pleasing way, i.e that the sound will appear rich and pleasent.

Reverberation is the phenomenon of persistence of sound in a big hall due to repeated reflection from the wall, ceiling and floor of the hall

Reverberation exists in all closed environments where air exists and there are sound reflecting walls/bodies.
