Hey Guys,
any one using any good acoustic modelling/simulation software out there?

LOTS of it!!!

Ulysses www.ifbsoft.de
free demo easy learning curve

Lara from integral acoustics
cheap, easy to learn

pricey, but industry standard
relatively easy to learn, when you don't have software bugs

expensive! free demo
Best quality!!! Great software no bugs
steep learning curve

D&B has a new prediction program for their loudspeakers specifically for line arrays and sub arrays.

EV has RACE, which is really easy and free.

Vdosc had Vision, but its dongle limited.

Odeon, hardware assisted pricey.

Ramseta from Angelo Farina
Not professionally used but gets good results.

Modeler from Bose

Extinct = Acousti-CAD, PHD, Elephant

If I missed any please let me know.

I would start out with Ulysses. Download the demo version and open one of the example files. predict the direct coverage and away you go. I also have three tutorials on using Ulysses on www.youtube.com/jevans111

I just used Ulysses to predict over 300 loudspeakers in about 5 minutes just last month! It told me which areas are intelligible, what areas would have an audible echo, and what areas just simply didn't have coverage. Much easier to fix these problems no rather than a year later when I cant pull cable.
