What is reverberation time?

The reverberation time is expressed in seconds and is determined by a couple of factors:

  • The dimensions of the room
  • The composition of the materials in the room (hard surfaces will yield more sound reflections)
  • The position of materials and walls in the room

When the reverberation time is too long, poor intelligibility and a rise in sound pressure will result in the problem of ambient noise. The installation of sound-absorbing materials ensures a reduction in sound pressure and better intelligibility.
