So far, we have never had the need to read the manual. This entire workflow chain outputs not only the weighted sound reduction index but frequency dependent results: using CadnaA for outdoor noise, Insul for inhomogeneous constructions, SONarchitect for building acoustics and Odeon for room acoustics. Looking at the workflow for acoustical prediction from outdoor noise over to building acoustics ending with room acoustics, SONarchitect is the missing piece in the puzzle.
No more quirky graphical user interfaces, but a well designed software that delivers good results. To put it in a nutshell, it is now not only possible to predict complex buildings' acoustics, but it is much more fun to simulate building acoustics than ever before. We recently changed from other building acoustics software and our own tools to SONarchitect.
