General Acoustic Simulation

Learn to use ODEON in the most efficient and correct way by watching our tutorials:

Working with Grids

Grids in ODEON part1: Define a Grid

This is a video on how to define grid area by choosing which surfaces the grid should cover, the height from the surfaces etc.

Grids in ODEON part2: Grouping Grids

This is a video on how to divide the grid response into groups, containing different surfaces.

Grids in ODEON part3: Multiple Grids on Same Surface and Grids on Vertical Surfaces

 This is a video on how to assign multiple grids to the same surface and how to have a grid on a vertical surface.

Grids in ODEON part4: Changing Scale and Colours of Grid Response

This is a video on how to customise the grid response by changing the scale and the colours to fit the purpose.

Grid features

Since version 11 the display of grid colour is based on an improved statistics. This is described in the video along with other small hints. Available in Industrial Auditorium and Combined editions.

Room Acoustic Parameter List

RAP-list visibility and save

Intro to the Room Acoustic Parameter list basic functions how chose what result parameters you can see. Room acoustics paramameters is not user definable in Odeon Basics and Odeon Industrial.

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.

Auralisation

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 separated by walls of a certain transmission.

STI calculations

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.

Advanced Tools

Using Genetic Algorithms to estimate absorption coefficient of materials

Using Genetic Algorithms to optimise materials in a room model in order to match simulations with measurements.

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.

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. Receiver grids are not available in Odeon Basics.

Materials

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.
