This software is not free but, in case its use was academic, you can ask Prof. Farina for an academic license.
Thank you very much for the useful information. I already knew DISIA, I had the opportunity to use it when I worked for ARPAV (Regional Agency for Environmental Protection). Now I'm curious to try i-simpa
It's also possible to use Predictor which is a Dutch product distrubuted by Bruel & Kjaer or CADNA, LIMA, Soundplan (German products as far as I know.
I use IMMI for outdoor propagation, it's not free, distributed in Italy by www.microbel.it.
For indoor propagation I have seldom used Ramsete, developed by Prof. Farina and distributed in Italy by www.spectra.it.
My favorite is SoundPLAN. The software is sold in Italy by Spectra. I have used successfully for the evaluation of the propagation of noise emitted by road, rail, parking and industrial sources.
The Edge Diffraction Toolbox by Peter Svensson. Multiple reflections are handled with the Image Source Method and multiple edge diffractions with the Biot-Tolstoy-Medwin method, which can gives the exact solution down to very low frequencies (unlike most other software based on beam tracing).
The Edge Diffraction Toolbox is entirely written in MATLAB, easy to use, flexible, can be very fast and accurate compared to FE, BE, Beam Tracing methods. It computes time and frequency domain solutions.

This toolbox was used recently to predict the outdoor propagation of sonic booms between buildings with excellent performance compared to BEM and good accuracy compared to experimental data: http://www.sciencedirect.com/science/article/pii/S0003682X12001004
which software can be used for propagation of sound during musical concert in open? Is it available for free download?
roomsim, Two!Ears, depending what you want to simulate. there are some free frameworks out there for maxmsp. I am not aware of anything for outdoors
Most software solutions merely simulate the room, and provide you simulated measurements and performance. That's great, but it tells you very little about how to improve your room. What we need is a design tool that can help you understand why your room sounds the way it is, and figure out how could we improve it. This is where an open-source solution like Pachyderm shines.

Can you tell me which software is best for urban sound analysis and simulation?
For outdoors we like Soundplan and Cadna-A. For indoors, mostly critical listening spaces, CATT
MCroomsim developed by an australian university. But unfortunately its not a real time software
which is better to simulate acoustic of a theater ????
Comsol or CATT ??? or other ??
CATT acoustic is better for theater simulations in my experience. You may also try to use AcMus developed by a Brazilian team.
