Thank you Thomas... That's what I thought from the very beginning! Now I understand my mistake - as you correctly pointed out - alfa is unit-less.
Thanks again,
A. |

My question was rather how to reverse-engineer the absorption coefficients from imperial to metric. Is it even possible?
I don't get what you mean here:
"If there are no different data for th ... |

| Hi again everyone! In my latest model, I need to simulate large audience area consisting of upholster seating. I found the right material in the EASE database, but it's american and all the coefficien ... |

| I swear that RT changed after I added scattering coefficients. Well, I guess that explains a lot of my problems... |

Thank you very much for these hints!
I have a problem with good calibration, because the hall will be split in thirds (to make the space smaller) and I simulated only 1/3 of the physical building t ... |

I can send you Eyring RT if that's okay:

| Okay. Finally I produced some graphs to show you how big is the issue. I've already spent hours looking for the cause and still have no idea how to troubleshoot. I still hope that you could help me gu ... |

Surely I know about the range limitations Thomas.
I designed two different panels for the bass frequencies - one tuned for 50Hz and then the ceiling one affecting 125Hz band. Still - these coeffic ... |

This is what I get from the SoundFlow (example structure):

Do you have any idea why is that guys?  |

Cool. Thanks for that Agustin!  |
|

|

Yeah, but should I scale all the coefficients in a "smooth way" or just "clip" the ones that are bigger than 1?
I'm testing the AFMG SoundFlow and when I specify the sample siz ... |

Thank you Pedro!
I'm still working on my model guys. As soon as I finish, I'll try to post the reflectogram.
PS. Do you know how to deal with coefficients bigger than 1? I've been trying to fin ... |

Thanks Thomas! I'll give it a go...
Btw. Could you guys recommend any books that are addressing simulation issues? I can find a lot of books on general acoustics, but there is not so much 'simulati ... |

Thanks for your reply! Unfortunately my budget doesn't allow for the AURA module.  |
