The time taken by the sound energy to ""fade away"" or decline in a confined or closed space is called reverberation.
Reverberation decreases when reflections strike surfaces that absorb sound like curtains, chairs, and even people.
The time required by the sound to minimize by 60 db is called reverberation time of a space.
The reverberation time for an hall without things is longer because many sound absorbers are present in a room which is crowded.
The sound in an empty room is reflected back by the walls because there is no absorbers present in the empty room.
