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.

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.

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.
