Question

what is reverbration how it can be produced

Answer 1

HI mate GM here is your answer...,

Reverberation,in  psychoacoustics  and  acoustics, is a persistence of sound after the sound is produced. A reverberation, or reverb, is created when a sound or signal is reflected causing a large number of 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. This is most noticeable when the sound source stops but the reflections continue, decreasing in amplitude, until they reach zero amplitude. Suppose a source produces sound which gets scattered in all directions in a closed room. Under these circumstances, repeated reflection of sound causes source to stop the producing sound. Reverberation canbe reduced if we can place some sound absorbing materials inside the room like curtains, plastic fireboard etc.

I hope it will help you and mark me as a brain list answer plz.
