Answer 2

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

To reduce reverberations, sound must be absorbed as it reaches the walls and the ceiling of a room. Sound absorbing materials like fibre board, rough plastic, heavy curtains and cushioned seats can be used to reduce reverberation.
