The authors of this paper investigated the ways to decrease the time of calculating an echogram in the computer simulation of the distribution of the sound field in a room. The authors emphasize the existence of a limiting moment tst up to which the simulation must be completed. The remaining part of the echogram may be treated as a stochastic amplitude (temporal distribution). The authors related the moment tst to the reverberation time RT and the early decay time, EDT, of a room.
