“…Under steady-state conditions, the energy balance requires just knowledge of the mean energy, the mean losses and the coupling mechanisms of the systems. The basic publications which were used for the development of the European harmonized standard EN 12354 (European Standard EN, 2000) are papers by Gerretsen (1986Gerretsen ( , 1979. As an illustration, Figure 7 shows the energy paths for a typical room-to-room situation.…”

Over the last decades, powerful prediction models have been developed in architectural acoustics, which are used for the calculation of sound propagation in indoor and/or outdoor scenarios. Sound insulation is predicted rather precisely by using direct and flanking transmission models of sound and vibration propagation. These prediction tools are already in use in architectural design and consulting. For the extension towards virtual reality (VR) systems, it is required to accelerate the prediction and simulation tools significantly and to allow an adaptive and interactive data processing during the simulation and 3D audio stimulus presentation. This article gives an overview on the current state-of-the-art of acoustic VR and discusses all relevant components in terms of accuracy, implementation and computational effort. With the progress in processing power, it is already possible to apply such VR concepts for architectural acoustics and to start perceptual studies in integrated architectural design processes.

Vibration transmission through structural connections is modelled in a deterministic way by means of modal analysis. This model is used first to study the effect of elastic joints across the floor in the transmission of impact noise. They are an effective means of reducing impact noise propagation, and can almost eliminate it for small values of the joint stiffness. The method is also used to study the acoustic relevance of studs in lightweight floor transmission. Different ways of modelling the studs are presented and compared. For the examples developed, the best option is to use springs for modelling the studs rather than more complex models involving springs and beams. Also the different behaviour of point and line connections is verified, as well as the influence of the position of the studs.

“…The simulation times in the beginning were in the ranged of hours but meanwhile they arrived at fractions of seconds (Savioja et al, 1999). In parallel to the progress in room acoustics, complex models for simulating vibro-acoustic problems such as sound insulation of buildings and transfer path analysis and synthesis in automotive industry were developed (Lyon, 1994;Gerretsen, 1986;Vorländer, Thaden, 2000). Thus the variety of applications have broadened as not only music and the quality of concert halls, or other performance spaces, are to be evaluated but also the perception of sound and noise in general (Vorländer, 2008).…”

Virtual Reality (VR) systems are used in engineering, architecture, design and in applications of biomedical research. The component of acoustics in such VR systems enables the creation of audio-visual stimuli for applications in room acoustics, building acoustics, automotive acoustics, environmental noise control, machinery noise control, and hearing research. The basis is an appropriate acoustic simulation and auralization technique together with signal processing tools. Auralization is based on time-domain modelling of the components of sound source characterization, sound propagation, and on spatial audio technology. Whether the virtual environment is considered sufficiently accurate or not, depends on many perceptual factors, and on the pre-conditioning and immersion of the user in the virtual environment. In this paper the processing steps for creation of Virtual Acoustic Environments and the achievable degree of realism are briefly reviewed. Applications are discussed in examples of room acoustics, archeological acoustics, aircraft noise, and audiology.
