==Origin==
[[Latin]] reverberatus, past participle of reverberare, from re- + verberare to lash, from verber rod
*[http://en.wikipedia.org/wiki/15th_century 15th Century]
==Definitions==
''transitive verb''
*1 : [[reflect]]
*2: repel
*3: [[echo]]
''intransitive verb''
*1a : to become driven back
:b : to become [[reflected]]
*2: to continue in or as if in a series of [[echoes]] : resound <an historic [[event]] that still reverberates today>
==Description==
'''Reverberation''' is the [[persistence]] of [[sound]] in a particular [[space]] after the [[original]] sound is removed. A reverberation, or reverb, is created when a sound is produced in an enclosed [[space]] causing a large [[number]] of [[echoes]] to build up and then slowly decay as the sound is [[absorbed]] by the walls and air. This is most noticeable when the [[sound]] [[source]] stops but the [[reflections]] continue, decreasing in amplitude, until they can no longer be heard. The length of this sound decay, or reverberation time, receives special [[consideration]] in the [[architectural]] [[design]] of large chambers, which need to have specific reverberation times to achieve optimum [[performance]] for their intended [[activity]]. In [[comparison]] to a distinct [[echo]] that is 50 to 100ms after the [[initial]] [[sound]], reverberation is many thousands of [[echoes]] that arrive in very quick [[succession]] (.01 – 1 ms between echoes). As time passes, the volume of the many echoes is reduced until the echoes cannot be heard at all.[http://en.wikipedia.org/wiki/Reverberation]
