Fundamentals and Software
Simulation

Emphasis is on sound transmission loss and vibrations of building components. According to requirements the physical basis of the calculations is the theory of thin plates or - for the more general problems - anisotropic elastodynamics. The developed software tools are used for analysis, prediction and optimization of building components.

 
Auralization

How good is the sound reduction of a construction or a building component? How good are the accoustics of a room? Questions, which experts answer with rating numbers and diagrams. But how does the room sound, how does exterior noise sound inside the room?

Auralization translates complex acoustic facts into close-to-reality hearing experiences. The acoustic effect of planning will become audible already in the design stage. A virtual acoustic test drive is reality.

 
Virtual Prototyping

Why only build three prototypes? Our simulation program allows to calculate hundreds of construction options over night and then compare them with the development aims definded in advance. Furthermore by means of auralization it is possible to listen to the acoustic properties of these prototypes, which are only available on the computer and to evaluate them subjectively. Despite a multiple of options, the development time as well as costs is considerably lower in comparison to the classical method of real prototyping.
