| Hi, i have a problem with a face.
I have create my room, and all work. now i need simulated a "moved barries" in wood.
So add a "face" without a thickness, and declare it as a "two fold".
if i check speaker aming, i can see that "line" interrupt when find "orange" face of my barrier... so ... i thought that is sufficent for Ease for understand that is a "wall". but if i go to analyze my room, on area behind my barrier, sound "arrives" as no wall/barrier is present...
so what i wrong? i have just checked "shadow cast" option.
i need create face with thickness? but in this case i need modify all my project. And i cant use "coat of" option, beacase barriers trought more face.
can you help me, plz? |

| really thanks, now is more clear (and with flag in Calculation tab, works 
but ... now, nothing pass throught my face, indipendent of material that i choose for it.
If i add a "barrier" and need mappig how many "sound" pass throught this face/wall ... what i need do? |

| i have a "mobile" wall, that divide my room in two o three indipendent hall.
so i'd like calculate how many "sound" of first hall "arrived" in my second hall, when i "close" it with mobile wall.
This "barrier/wall" is in wood, "have two fold", declare as wood grid.
(i have try o change material with ABSORBED, ma mapping doesn't change) |

| Hi Marco,
EASE is mainly concerned with architectural acoustics problems in a single acoustic environment. Wich means that it won't model the transmission of sound through surfaces or structures. But only how much sound it absorbs and reflects back, based on the material absorption coefficients.
This means that the barrier in your room will either stop sound completely or be 100% transparent, depending on your Shadow Cast setting. This might be accurate or not depending on the frequency of interest. For instance, small surfaces could be transparent to sound waves with large wavelengths, whereas large surfaces could actually block the same frequency. So, the question is really about the importance of that surface (or barrier) in your room.
Do not model coupled, separated rooms. Make one model for each different acoustical environment.
Hope this helps,
Pedro Lima |
