Reverberation
Reverberation (reverb) is the term used for a persistence of sound after a sound is produced. Itis created when an audio signal or a sound is reflected and results in multiple reflections. The sound can be built up or decayed as it is absorbed by the surfaces. This can be noticed specially when the reflections persist even after the source stops generating the sound.
Reverberation is frequency dependent: the length of the decay, or reverberation time, receives special consideration in the architectural design of spaces which need to have specific reverberation times to achieve optimum performance for their intended activity.
The observation of reverberation at different locations are different from each other and there are several causes and circumstances that lead to it.
These observations can be modelled using the functions in the audacity application, to observe the effect of reverberation under different circumstances.
