The persistence of sound in large halls or auditoriums due to repeated reflection from the surfaces is called Reverberation
To reduce reverberation, the roof and walls of the auditorium are generally covered with sound-absorbent materials like compressed fibreboard, rough plaster or draperies. The seat materials are also selected on the basis of their sound absorbing properties.
