✦ Synopsis

The paper concerns extrapolation of number of visible image sources and average image source distances to higher-order specular reflections from loworder calculated results. For closed rooms, the number of visible sources follows a second-order function while the distance curve approaches a straight line. Comparisons are made with results from a parallelepipedic room, Jbr which it is possible to efficiently calculate image sources correctly up to high reflection orders. To establish the extrapolation functions it is desirable to calculate the positions of images for as many low-order reflections as possible. The paper therefore also discusses methods that might be used to accelerate such calculations.
