General acoustic simulation

Odeon intro An intro video that starts with import of room and finish with small auralisation.

The Point Response in the Joblist
A short video that navigates throughout the tabs of the point response within the job list. The video teaches you how to interpret the different displays and which keyboard short-cuts to use.

Diffraction of wall types
A video on when to use fractional, exterior or normal wall types to compensate for curved surfaces modelled as many plane surfaces or detailes that are not actually in the room model. see how ODEON looks differently on exterior and interior surfaces in a room.

STI with background noise
How to use the noise sources modelled in the Room acoustic modelling software ODEON as a basis for calculating the Speech Transmission Index STI.

Grid layout (before version 11)
Define a receiver grid in the room acoustic modelling software ODEON from www.odeon.dk. See how to change the color scale of the acoustical parameters in a grid, like speech transmission index STI, SPL(A), T30 etc.

Version 11 Grid features
In version 11 the the display of grid color is based on an improved statistics. This is described in the video along with other small hints.

Material library data
How to create a spreadsheet from which acoustic absorption data can be imported into the room acoustic simulation software ODEON. And how to import from this spredsheet into the material library. See more

Sound transmission
How to add sound transmission as a reduction index [ISO 140, part 4] in 1/3 octave bands to single or double walls in ODEON for calculation of the resulting room acoustics with transmission of sound.

Auralisation with mixer
How to mix a soundscape or a multipoint auralisation with use of the ODEON mixer. This example makes auralisation with several sources some being in the same room and some in an adjacent room seperated by walls of a certain transmission.

RAP-list visibility and save
Intro to the Room Acoustic Parameter list basic functions how chose what result parameters you can see.

RAP-list adding and editing parameters
How to ad and edit a room acoustics frequency parameter or a Room acoustic wide band parameter in the RAP-list to customise your results.

How to trace a flutter echo. Queens Hall, Copenhagen, Denmark.




Room modelling and import

SU2Odeon
Model rooms with SketchUp and make them available for ODEON with SU2ODEON. The SU2ODEON plug-in makes SU-models compatible with the requirements set by ODEON so you can manage geometries in SU and acoustics in ODEON.

Making an Auditorium with SketchUp
A series of tutorials on how to build a complete project in SketchUp. We start by making a primitive shape and then we modify it. Only the most important details are kept, so that the room is suitable for acoustic simulations. The model can be imported into ODEON with the SU2ODEON plug-in.

From IFC models via SketchUp to ODEON
Use SU2ODEON as a tool for handling Building Information Models from the IFC format in ODEON.

Introduction to the Extrusion Modeller
Introduction to the Odeon Extrusion Modeller - version 3.0

Combine two Extrusion models
Video describing how to combine a cross section and a plane section of two extrusion models with the parametric editor in ODEON.

Importing a .3ds or .dxf model and trimming it.
How to draw surface in the modelling view.
Find the Z-coordinates, relative to a sloped roof.
How to manage room modelling in ODEON


Loudspeaker simulation

Array Loudspeaker modelling
How to use the array source editor in ODEON for creating array loudspeakers by setting loudspeaker units distances delays and gains. Also showing a variety of available graphical display options.

Place array loudspeaker in room model
Tools to make it easier to place an array in a room model for calculation of the combined room acoustics and electro acoustics.

HAAS effect
How to use the HAAS effect to acheive localization towards a speaker or performer with several loudspeakers present in a room. How to download loudspeakers from the Common Loudspeaker Format. Auralisation og loudspeaker setup with and without use of the HAAS effect function.


Impulse Response Measurements

Measure Room Impulse Responses with ODEON
A short video describing how to use the sweep generator in ODEON for obtaining high-quality impulse responses.


Acoustic theory behind

Rays and particles
Hybrid methods in ODEON combines ray tracing, image source modelling, and secondary source modelling.

Scattering
The Reflection Based Scattering Method applied in ODEON makes sure details in models such as chairs and table will automatically be taken into account in simulations- making it much easier to apply scattering in the model.
