2.3 Pre-calculated Rooms – Round Robins Odeon©1985-2005 4 6 1 calculated by ODEON with those measured in the real rooms: P1 3 P2 5 2 At this point you have tried the basic functions in ODEON and may want to view results for more realistic rooms. In the room directory you will find pre-calculated results in the rooms Elmia RoundRobin2 detailed.par and PTB_Studio open curtains detailed model.par which were the rooms used as test objects in the 2 nd and 3 rd Round Robins (Bork, 2000; Bork, 2005). Geometry, absorption data, source and receiver positions as well as the measured room acoustical parameters are those supplied to all participants in the Round Robins, by the PTB in Germany - these data are publicly available at www.ptb.de. To compare results Open the room in question. Open the JobList – the Shift+Ctrl+J shortcut. Select one of the pre-calculated Multi point response jobs (job one or two) in the Joblist and open it – the Alt+M shortcut. Select the Measured versus simulated tab-sheet in the Multi Point display. 1 P2 P1 3 2 Odeon©1985-2005 A couple of other examples Hagia Irene.par is a model of a Byzantine church in Istanbul which like the examples above also includes the measured room acoustical parameters. 10 9 7 3 8 2 1 P1 11 4 5 6 Odeon©1985-2005 22 20 S29 S27 S25 S26 19 S31 S32 S34 S35 S24 S30 S33 S37 S38 18 S36 S40 P41 P22 P23 P42 13 17 S39 21 S28 15 14 23 16 Odeon©1985-2007 24 11 12 10 8 S8S6 S4 7 S10 S11S13 S14 6 S3 S9 S12 S16 S17 P21 S15 S20 P19P21 P44 1 5S18 9 S7 3 2 4 Another example Studstrup.par is also available; this is a model of a turbine hall at a power plant – measured SPL(A) is included in that example. This example is only available for the Industrial and Combined editions. If you wish to carry out faster calculations, you may enter the Room setup and select the Engineering setting this will provide results approximately 2 times faster without much loss in quality in results. 2-33
2-34 Copenhagen Central Station Array.par is available in the Auditorium and Combined editions of ODEON. This example demonstrates the newly installed PA system which utilizes 20 beam steered line arrays. Several measured parameters are available including STI.
