Hi,
I'm new here and have a question to the performance of Acousto. We have to design a sliencer for an exhaust fan in a metro system. We know the sound power of the fan. Is it possible designing the silencer and compute the sound pressure at the shaft outlet in 1m distance of the outlet?
Between the fan and the shaft outlet a more or less complex duct system has to be considered. The silcencer has to guarantee a limited sound preassure at a defined point (1m distance of outlet).
Is Acousto a software to solve that problem?
THX for your help!

Hi,
current version of acousto (1.6) does not support moving boundaries, moving sources nor background flow. If this is your case, then Acousto can address the problem. The only limitation comes from the highest frequency of interest. We have done a lot of simulations of wind musical instruments, which is a problem very similar to a muffler, with excellent results up to 6 kHz. Geometry complexity is not an issue, provided that your coimputing system hs enough RAM memory.
Hope this help.

PS: v2.0 is about to be released. Stay tuned...
