Question

what is reverberation and how it is reduced ? ​

Answer 1

Explanation:

Persistence of sound (after the source stops producing sound) due to the repeated reflection is called reverberation.

Reverberation can be reduced by absorbing the sound using some materials as it reaches the wall and ceiling of the room and thus prevent the sound from getting reflected. Some materials which are used to reduce reverberation are fibreboard, heavy curtains, plastics etc.
