Calculation parameters, noise & air conditions

After a calculation, it is important to take a look at some of the preliminary results to gauge whether your calculation parameters were appropriate. Then, you can adjust the calculation parameters and re-run the calculations so that your results are more reliable.

The most important calculation parameters are the impulse response length and the number of late rays. Other miscellaneous parameters are also described, such as background noise for STI and air conditions for air absorption.

Specialist settings

Many users do not need to change the values in the specialist settings, but for the experienced user it can be a way to change the calculations in ODEON.
