Room acoustic computer simulations are an important planning tool in this day and age. Not only are they used for concert halls and opera houses, but also for smaller performance spaces and office environments. They provide objective acoustic criteria that allow for a more precise evaluation than that provided by conventional calculation method.
We use 2D and 3D architectural designs (e.g. AutoCAD, Rhino, and SketchUp, as well as other formats) as the basis for a three-dimensional acoustic room model. The acoustically relevant spatial information is reduced using specially developed software. All of the surfaces are assigned acoustic reflection properties depending on the planned materials. We simulate the transmission of sound in the room, from the source to the listener, using state-of-the-art simulation techniques and proprietary methods. The results are evaluated both numerically and graphically and provide information on any necessary adjustments to the materials or geometry. Altogether, they help to achieve the best possible harmony between visual and acoustic design.
We also use three-dimensional spatial models for line of sight tests during planning. And last but not least, we use computer models for room acoustics auralisation, i.e. listening in virtual spaces.
