Structure-Borne Sound,sponding elastic reactions. In contrast to fluids, solids can react with elastic forces to pure deformation. The number of possible waveforms is therefore higher. And these waveforms can interact and exchange energy, depending on the geometric and elastic coupling in the specific shape of the solid

Psychoacoustics,re concerned, however, human beings as the final recipient of sound are the final authorities on sound quality, comfort or annoyance. Basic knowledge about the human hearing system, its anatomy and neurophysiology, thus, provides us with a deeper understanding of how auralization must be organized a

Characterization of Sources,vity. And the sound signal, the temporal function of the generated sound, is the main input signal for auralization technology. Physical modelling, recording, and sound synthesis can be used for obtaining signals. Databases of frequency-dependent directivities, possibly more aspects with regard to t

Convolution and Binaural Sound Synthesis,uter simulation. By adding the effects of the environment to the dry sound, we imprint the specific sound character the specific environment into the source. The classical mathematical tool to achieve this is convolution. It can be implemented in brute-force algorithms or in block processing based o

Simulation Methods,ynthesis or other spatial audio formats, and after having characterized the sources, we will now focus on the second key component of auralization. We consider the excitation signal as known and ready for convolution. Now, the propagation functions for sound and vibration must be measured or modelle

Simulation of Sound in Rooms,cy. It will be shown that pure specular models (image models) are not capable of simulating room sound fields sufficiently accurate. But combinations of models of image sources and statistical models such as Ray Tracing and radiosity will allow a simulation with acceptable plausibility. Hybrid model
