Can I include sound transmission in an ODEON simulation?
ODEON includes airborne sound transmission through a wall via a sound reduction index. To do so, you should use the “Transmission” wall type in the Material list. Please not that flanking transmission is not included in ODEON simulations. If you know the influence of the flanking transmission you can manually include it in the sound […]
Can I make simulations in a room when there is loss of rays?
Ideally, a room should be watertight, to ensure a sufficient population of rays to model the sound decay accurately. The amount of allowed ray loss is specified in the Room setup and is 10% by default. If this percentage is exceeded, ODEON will stop the calculation. Generally, you should make sure that the reflection density […]
How to optimize Grid Response calculations?
For initial grid calculations, consider using larger distances between receivers or multi-point responses with receivers placed at strategic positions. Since version 15, ODEON interpolates colours between grid receivers, ensuring smooth visual results. However, a detailed grid calculation is recommended at the final stage for greater accuracy.
How to optimize calculation speed and quality for point responses in complex room geometries?
To speed up point response calculations (Auditorium and Combined editions only), try making a calculation at one of the most critical positions, e.g. where coupled room effects are present. If the quality of the results above is not satisfactory, increase the number of rays in the Room Setup: For example, doubling the number of rays shouldresult […]
How do I calculate Speech Transmission Index (STI) with a certain Signal to Noise Ratio (SNR)?
A proper calculation of STI requires the background noise level in the room to be specified, which determines the Signal to Noise Ratio . Click here for a video on how you can use sources in ODEON to find the total background noise level and add the background noise level in an STI calculation.
