What is reverberation time?

The reverberation time for a sound is the time it takes for the echoing sound to diminish by a factor of 60 decibels, that is, to 1/1,000,000th of its original intensity. The longer the reverberation time, the more echoing is heard because the sound has reflected off walls and other surfaces. The shorter the reverberation time, the less echo is heard.
