Question

What is reverberation? How can it be reduced?

Answer

Reverberation:
The persistence of sound in a big hall due to repeated reflections from the walls, ceiling, and floor is called reverberation.

How to reduce it:
Reverberation can be reduced by using sound-absorbent materials, such as:

  1. Covering the roof and walls with compressed fibreboard, rough plaster, or draperies (heavy curtains).

  2. Using seat materials that have sound-absorbing properties.
