Lyngby Denmark Tel: +45 8870 8845 Fax: +45 8870 8090 www.odeon.dk Thank you for using ODEON, the Room Acoustic Software package that helps you make complete studies of room acoustics for any space through simulations and measurements! We hope you will enjoy working with ODEON and that you will find it extremely useful in the acoustical design of new spaces and improvement of existing ones. ODEON has a very user- friendly interface, which allows setting up a project very fast, and elegant presentation of results. This manual is intended to serve as an introduction on modelling room geometries in ODEON software, on the facilities for measurement and simulations, and the applied calculation principles behind. It will not cover in depth all facilities included in the ODEON software; explanations of displays, calculation parameters, results, etc. are available as context sensitive help from within the ODEON applications (shortcut F1). It is recommended to use the online help to learn about the specific features available from the different displays, the interpretation of results, calculation parameters, etc. The contents of this manual are as follows: Chapter 1 covers installation of the program, changes from previous versions etc. Chapter 2 covers geometry modelling. New releases of ODEON often include new facilities which can speed up the modelling process as well as tools for verification of geometries. Some of the facilities are; a plug-in for Trimble SketchUp, extensive support for import of CAD models in the .dxf as well as the .3ds (3D Studio) format and a stand-alone drawing program for modelling of the so called extrusion models. Tools for verification of room models are also covered in this chapter. With improved support for 3rd party tools for geometry modelling, knowledge about ODEON parametric modelling language is becoming of less importance. The advanced user will find that the description of the .par format has been moved to Appendix E. The format features support for symmetric and semi-symmetric rooms, use of constants, variables, counters, loops etc. and can be useful when studying geometrical parameters such as angle of reflectors, etc. As all geometry, also imported ones, are stored in the .par format, it is possible to add features described in terms of parameters to an imported geometry if familiar with this format. Chapter 3 describes the type of sources and receivers, how to extend the library of directivity patterns available for point sources, and the use of directivity patterns in the Common Loudspeaker Format, CLF. Chapter 4 deals with the materials to assign to the surfaces of the rooms; absorption, scattering and transparency coefficients as well as transmission data. Special materials that may speed up the modelling process and how to manage the material library are also covered in this chapter. Chapter 5 deals with the auralisation options in ODEON Auditorium and Combined; the hardware requirements, how to publish calculated sound examples on the Internet or on audio CD's etc. Chapter 6 introduces the calculation principles used in ODEON, giving an idea on the capabilities and limitations of the simulation part of the program. Chapter 7 describes important calculated room acoustic parameters available in ODEON, how they are calculated and how to interpret the results. 1 Chapter 8 describes the various calculation parameters available in the program. Most of the parameters are automatically set to reasonable values by ODEON; however for special cases you may need to adjust some of the calculation parameters. Chapter 9 is the discussion on quality of results and how to achieve good results. This chapter may be relevant once familiar with the program. Chapter 10 introduces the line array sources discussing some basic principles behind array source design. Chapter 11 presents the integrated impulse response measuring system in ODEON. The chapter explains which measuring methods are used, how to obtain a healthy impulse response and how to obtain room acoustic parameters as the results. The chapter ends with an annex giving examples of good and bad impulse responses. Chapter 12 describes how to use ODEON’s Genetic Material Optimizer for calibrating a room model towards a real room. The Genetic Material Optimizer makes use of genetic algorithms in order find the list of materials (absorption coefficients) that lead several simulated parameters to match with measured ones. 2 This legal document constitutes the complete agreement between you, the end user (either an individual or a single entity) and Odeon A/S.

As the licensee, you own the magnetic or other physical media on which the ODEON program is subsequently recorded or fixed. This Agreement is not a sale of the original ODEON software or any copy thereof. All rights are reserved by Odeon A/S. In consideration of payment of the License fee, Odeon A/S grants each customer (a private person or a company registered in a country) a non-exclusive right to use the ODEON software. This Agreement grants you the right to make copies of the software for archival purposes, and to copy the software on the hard disk of your computer. The software may be loaded onto multiple computers, but can only be fully operational on a single computer at any given time. The computer operating the ODEON software needs to have the hardware key delivered with the software attached to the USB port. Granting of a license is bound to ODEON software use with a hardware key. The hardware key holds the license information and determines the version and edition of the ODEON software that can run when the hardware key is attached to the computer. If a hardware key is defective during the warranty period (first licensed year), Odeon A/S will replace the hardware key. The customer will pay the hardware key fee for replacing the hardware key should it become defective after the warranty period. The hardware key contains the name and country of the licensee which are displayed in the software, on print outs from the software and on graphics exchanged from the software. The ODEON Combined Demo version of ODEON has limited functionality and runs without a dongle. 3 The modification, adaptation, translation, reverse engineering, de-compiling, disassembling, attempt to discover the source code of the software, or the creation of derivative work based on ODEON software is strictly prohibited. In no way may you transfer, assign, rent sublicenses, lease, sell, or otherwise dispose of any portion of the software on a temporary or permanent basis. The ODEON software is licensed only to the licensee. In no way may you transfer, assign, rent sublicenses, lease, sell, or otherwise transfer any portion of the license on a temporary or permanent basis (this includes transfer between branches of international companies that are registered in different countries). The license may only be transferred to anyone if Odeon A/S accepts (e.g. in the case of merging two companies) and with the prior written consent of Odeon A/S. Any authorized transfer of the ODEON software shall be bound by the terms and conditions of this Agreement. This license is effective until termination. This license will terminate automatically without notice from ODEON A/S if you fail to comply with any provision of this Agreement. Upon termination, you shall destroy the written materials and all copies of the ODEON software, including archival copies, if any.
