A: In order to speed up point response calculations, try making a calculation at one of the most critical positions, e.g. where coupled room effects are present. (Auditorium and Combined editions only)
Before calculating the point response, set the calculation parameters in the Room Setup. Use the standard Engineering setup as a basis. Set the Impulse Response Length to a value between 2/3 and 1 times the expected Reverberation time. Set the Impulse Response Resolution to a value around 1/1000 – 1/500 of the Impulse Response Length.
Calculate the point response in the selected critical position.
Check the following in the Single Point Response (Auditorium and Combined editions only)
If the quality of the results above is not satisfactory, the Room Setup should be changed as follows
If the quality of the results above is satisfactory, but you want to minimize the calculation time, try decreasing the number of rays and shortening the Impulse response length.
If you are in doubt whether the results are good enough or not, try to run a point response calculation using the Precision setup. In most cases this will create a very high reflection density, but in rare cases like an open air theatre the number of rays may need to be set even higher. Use the calculation results as a reference, i.e. the results obtained with the optimized setup should not deviate significantly from these results.
Grid Response calculations
For initial calculations consider using a grid with large distances between receivers or instead use Multi point responses with discrete receivers at strategic positions. Only for the final calculations make a detailed grid calculation.
