The gap between direct sound and reverberation encodes the perceived size of a space
Evidence
The time taken for reverberation to occur is a function of the size of the room and will be shorter for smaller rooms, due to the shorter time between reflections and the losses incurred on each impact with a sur face. In fact the time gap between the direct sound and reverberation is an important cue to the size of the space that the music is being performed in. Because some of the sound is absorbed at each reflection it dies away eventually. The time that it takes for the sound to die away is called the reverberation time and is dependent on both the size of the space and the amount of sound absorbed at each reflection. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1776
