A complex of many reflected sounds occurring in an enclosed space such as a building or cave. The effect is often confused with echo which, strictly, is a discrete repeat of a sound event. Reverberation occurs to some extent in any place where a sound can occur, but is most noticeable in very large places with many hard reflective surfaces which are at complex angles to one another, such as large churches etc. Most people are able to recognise particular types or reverberation and can associate these with imaginary rooms of varying sizes. Devices for the artificial creation of reverberation ( sometimes called "room simulation") have been available for some time. Initially based on electromechanical devices such as reverb springs or reverb plates, these are now usually digital devices. Several distinct phases are observed in the evolution of a reverberative sound and these include pre delay, early reflections, high & low frequency damping, decay. |
