  • Reverberation is the phenomenon of persistence of sound after it has been stopped as a result of multiple reflections from surfaces like furniture, people, air, etc within a closed surface area.
  • Reverberation time depends on the size and shape of the room. It is directly proportional to the volume of the room, the more the volume, the more the reverberation time.
