✦ Synopsis

This paper presents a means of solving equations of the form used in statistical energy analysis of sound transmission. It deals with the calculation of the sound transmission for the case of several acoustic power sources placed in an arbitrary structure consisting of any number of rooms, separating panels and cavities, by using the statistical energy analysis (SEA). A set of simultaneous equations, which arise from the appli6ation of SEA to multiple path systems, can be obtained on a computer by using a particular algorithm. For this case, the sound pressure level in each room can be calculated. The method of calculation for the case of one acoustic power source, namely the calculation of the sound insulation, is explained as a.special case. The general method of solution for one or several acoustic power sources is described. A simple matrix has been established for the generalized solution. Examples for using the generalized solution are given.
