This list of videos goes through all the steps required to get acoustical results from scratch, following the appropriate setup order. Then, you can watch our other video tutorials for alternative ways to make calculations and other more specialised functions.
We also have a quicker 20-minute video showing the full workflow on a single model, going through the steps in simpler detail.
This sequence of videos is also available as a YouTube playlist.

3D room geometries are not made within ODEON, but rather, the user typically imports models created in an external CAD software.
However, 3D models for acoustic simulations in ODEON need to be made with different considerations than 3D models for architectural visualisation.
This video explains the most important guidelines to follow when creating your own rooms to import into ODEON.
0:00 Intro
0:44 Recommended room sizes
1:59 Highly-detailed models

The 3DView is the go-to window for examining the geometry in ODEON. But it contains more than the obvious options, as is shown in this video.
0:00 Intro
0:48 Viewing and changing the preview
1:31 Rotating, moving, zooming
2:37 Using and adding default views
3:36 Projection, rulers, dimension units

Just like a real measurement, to simulate an impulse response it is necessary to have at least 1 source and 1 receiver at specific positions.
Point sources can be assigned a directivity balloon and sound power by octave bands. Sources and receivers can be tabulated into an array.
Line sources and multi-surface sources are available in editions Industrial and Combined. Line sources are useful to model long sources like pipes with running water and conveyor belts, while multi-surfaces are useful to model large industrial machinery.

In order to calculate reflections, acoustic properties such as absorption and scattering must have been assigned to surfaces.
Absorption coefficients, or “materials”, can be easily assigned to groups of surfaces, making the process easy even for complicated models. ODEON comes with a library of materials ready for use, which can also be customized. The video also shows how to use scattering and transparency coefficients.
0:00 Intro

1:41 Material library
3:39 Assigning absorption coefficients
5:35 Adding new materials
7:36 Global and local room libraries

10:22 Scattering coefficient
13:06 Transparency coefficient
14:17 Bounding box for outdoor acoustics
15:10 Outro
This video covers the impulse response length and number of late rays. These are the most important calculation parameters, which should always be manually defined for every room model. Other miscellaneous parameters are also described, such as background noise for STI and air conditions for air absorption.
0:00 Intro
0:38 Impulse response length
1:35 Quick Estimate
2:48 ODEON’s calculation methods
3:36 Number of late rays
5:44 Global Estimate
6:29 Ray loss
7:10 Outdoor simulations
8:11 Background noise
Finally, time to run a simulation and calculate some results!
The multi-point response is the impulse response calculation from your active sources to all your receivers. You’ll get all the numerical values you need to comply for ISO 3382-3, as well as bar graphs and statistics. You can even overlay measured and simulated data for comparison.
The single-point response is available in editions Auditorium and Combined, and focuses on a single receiver to obtain more detailed data, such as the decay curve, reflectogram, and binaural impulse response.
