The principle of calculations is shown in Figure D2. Statistically 10% of the balls (rays) are transmitted and 90% are reflected. However this is compensated for in the calculations, so the energy losses in the two rooms are determined by the absorption coefficients and reduction indexes, as used. Figure D3 The Transmission Rooms.par sample is installed with ODEON. The Figure illustrates how transmission data are assigned to transmission walls, when transmission walls are composed from a single surface, two surfaces and three surfaces. Once the room has been loaded into ODEON, additional information is available in the Notes editor using the Shift+Ctrl+N shortcut. In the Joblist, some example setups have been prepared for calculations in source rooms as well as in receiver rooms. 12-134
