Odeon is used for many acoustic research purposes, which brings up questions like the ones below

Q: I would like to divide my room-model with curtains or a thin plastic material and analyze the absorption. Can I use sound reduction Index for this?

A: If you are not particularly interested in the result in receiver positions on the other side of the "walls", we cannot recommend to use the sound transmission modelling. Particularly with low sound insulation (R < 10 dB) the method has some drawbacks, please see paper from BNAM 2008.
You can either use absorption only, or a combination of transparancy (same for all frequencies) and absorption; this will work as shown on the last page of this old Powerpoint presentation.

Q: I use Odeon to simulate the spatial sound field distribution at a receiver. Odeon's reflectogram reports the incident sound field distribution for the early part only. Is the rest of the response stored somewhere for me to access?

A: If you do text export from the Decay Curve in the Single point response (Ctrl A), Odeon will not only export the normal energy-time histogram (with the resolution given in the ‘Room Setup’, also the intensity given by X,Y,Z composants are given: This text-export include early (specular as well as scattered) and late energy. It is not the individual reflections rather a sampling with a selected time resolution.
