Tutorials about Materials and Wall Types

In order to do simulations in ODEON, all surfaces in the room need to get acoustics properties. In the material list you can choose absorption coefficients from our material library and add scattering. You can also add transparency or transmission for the surfaces.

Material List Overview

Overview of the Material List and the options you have there.


Material libraries and adding materials

The Material Libraries contains absorption coefficients for a huge range of materials available in ODEON. 


Importing material absorption coefficients from Excel sheet

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 spreadsheet into the material library.

Setting scattering and transparency coefficients

​Manually set absorption coefficients, scattering and transparency.

Quick estimate of reverberation time

Make a quick (not 100% accurate) estimate during the setting of material, in order to follow the development of the acoustics in relation to the material. 


Wall types

Walls can be configured under different types in ODEON Room Acoustics Software. It is important to know when each of these types are applicable in order to obtain accurate results.

In this video, we take a look at:

• Wall type options
• Exterior walls vs. interior walls
• Interior margin
• Visualising exterior and interior walls
• Fractional walls
• Scattering for different wall types
• Selecting type for many surfaces at once
• Wall type effects visualised with 3D billiards

Sound transmission & industrial noise auralisation

If you have your reduction indices/transmission loss values in 1/3 or full octave bands, you can add transmission properties to walls in your model. And if you have ODEON Auditorium or Combined, you can also listen to the result of adding transmission to your model. Here, we show an example in an industrial scenario.

This video covers:

  • Configuring transmission wall type
  • Number of transmitted rays
  • Entering reduction indices from Excel
  • Manually entering/generating reduction indices
  • Adding reduction indices to double walls
  • Setting up auralisation of transmission
  • Adjusting and listening to auralisation
  • Setting acoustically transparent surfaces
