I made some tests with charles' model (varying RT's, noise, levels, checked
Mapping vs. Aura) - there is nothing unexpected. In general.

Ok, perhaps my answer was to short.
I think the conventional horn wouldn't improve the STI in comparison with the music horn in the room you described (explanation above). And therefor I don't see, t ...

STI is a weighted sum of the MTI's (definition of STI!).
If you want a higher STI, you have to improve one MTI at least.
Since MTI is roughly speaking a SNR, without a signal (only noise left) it ...

The question is, is it rigth to set MTI=0 for bands that aren't feeded with a signal?
Yes, I think so. Under optimal conditions (no noise, no reverberation, just direct sound with an apropriate level ...

STI is calculated from the MTF. Look at the MTI-values in the View window. There you can see what happens.
The conventional horn (sensivity =0dB for low and for high frequencies) produces MTI values ...

the setting "length" I mean was on the AURA->caculation->length(ms), my question was:
Was the length means the decay time or something else?

I'm talking about the length of ...

What is " the interrupt time of the sound"?
I'm talking about the length of the simulated part of the impulse response (IR). To calculate T30, you need a decay of 40 dB (=2/3T).
I'm conf ...

Hi,
you can't find anything about rock, punk, post rock in the original paper, mentioned by alexis. But it is interesting to read anyway.

In the EASE Help I find:
Appendix A: Acoustic Formulae & ...

Don't compare simulation with the measurement result before your simulation is stable!
Ok, I don't know your room. But 25k particles aren't enough for sure!
I just tested it with a 175 m^3 shoebox ( ...

or I just go to try until the result was fit the field result?
No, first You have to look for a stable result!
Stable means here, that parameters calculated with the IR don't change
with more part ...

Hi,
note that you have to adjust the number of particles to get a
stable simulation result.
I've good experience with length(IR) approx. 2/3 T.

If you want simulation results that fit the meas ...

Hi charles,
for inserting an object (menu Insert/Object) a saved object is required.
You can save an object with the right mouse button menu ("Save As").
So using this object in different ...

Hi charles,
less calculation points (lower resolution) and/or less faces speed things up.
Perhaps you don't need the same resolution for every part of your "audience
area" and it's possib ...
