Execution parameters in a sound ray computer program (time discretization step,...) can influence the calculated echograms and their associated room acoustics parameters. An improved procedure is proposed to control this influence through a numerical processing of the raw calculated echograms. This procedure replaces the less accurate part of the echogram by a suitable theoretical decay. Examples are presented.
