Figure D2 3DBilliard display illustrating Transmission through a double sided wall – as can be
seen, ODEON understands correctly that balls should jump through the wall, from one surface
to another.
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.
