Q
Sound

Question:

What is reverberation? How can it be reduced?

Answer:

Reverberation: The repeated reflection of a sound from the walls, ceiling and floor of the hall that results in this persistence of sound is called reverberation.

To reduce reverberation, the roof and walls are generally covered with sound-absorbent materials like compressed fibreboard, rough plaster or loose woollens. The seat materials are selected based on their sound-absorbing properties.
