✦ Synopsis

The ODEON room acoustics program is intended to be a base for research in objective and subjective room acoustics, and a useful tool.for consultants. The program uses a hybrid method, in which an initial ray tracing is carried out to determine potential reflection sequences. These may later be tested .for visibility at an), number of receiver points. For the early part of the reflectogram, stringent visibility tests are made, and visible images are treated according to normal image source theory. The ray tracing data is also used to generate a plausible reverberent energy-time function with high reflection density, by assuming a homogeneous reverberant field. The energy of each of the reverberant images found is corrected to account for the difference between the number of images found and the number expected from theory. Details of the calculation principles are presented, including a number of optimisations which can be used in man), types of model. The program version discussed here is 1"5.
