Reverberation - Wikipedia, the free encyclopedia
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 ...

In order to provide a reproducible parameter, a standard reverberation time has been defined as the time for the sound to die away to a level 60 decibels below its original level. The reverberation time can be modeled to permit an approximate calculation. ... What is a desirable reverberation time?

Reverberation time (RT60) is defined as the time required, in seconds, for the average sound in a room to decrease by 60 decibels after a source stops generating sound. Reverberation time is the primary descriptor of an acoustic environment.

In theory, it is easy to determine the reverberation time of a room. It depends on the volume of the room and the rate at which the sound energy is absorbed by the wall surfaces and the objects in the room. In a bare room, the reverberation time is thus proportional to the ratio of volume to surface.

Finally, the room will possess a reverberation time RT60. This is the time in seconds required for the steady state sound level to drop 60 dB after the sound source has been turned off. ... We will also calculate and measure the reverberation time in McKinnon Theater (a small auditorium in the GMI Academic Building).

Reverberation time refers to the amount of time required for the sound field in a space to decay 60dB, or to one millionth of the original power.

In audio, a decay by (one time-constant) is not enough to become inaudible, unless the starting amplitude was extremely small. ... Thus, is about seven time constants. See where is marked on Fig.4.7 compared with .

Wallace Clement Sabine was the first to quantify this subjective quality in the early 1900s. He developed the quantity Reverberation Time (RT), which is defined as the time it takes for sound energy to decay 60 decibels (dB). One can measure this in an existing room, by measuring the length of time for sound to decay 20...
