The practical calculations of the first reflections from elements comprising the boundaries of an auditorium (such as a rigid plane panel, a rigid curved panel, and a panel having reflection coefficient other than unity) have reported. Multiple reflections between two rigid plane panels, two rigid convex panels, two plane panels with reflection coefficients different from unity, and those inside a rigid concave panel have also reported, based on the calculation of the first reflection. In this report, Terai's boundary integralequation is transformed by the successive substitution where early terms correspond to the early reflections. For each term, the equivalent result reported previously is applied. Finally, the calculated pulse response of the early reflections in a scale model auditorium, which is the convolution of the calculated impulse response and the direct sound simultaneously obtained, is compared with the measured result. It is shown that the sum of the reflections in a several orders correspond well to the measured early reflections and that the details of the formation of the sound field can be discussed on this method.
