The acoustic propagation of sound in the open field or in the interior can be calculated efficiently and in high quality by geometric simulation methods. However, for correct simulations, accurate surface parameters such as absorption and scattering coefficients are required. In this thesis, the scattering coefficient of different facades is simulated with established numerical methods. […]

Nowadays, more and more conversations are conducted via technical aids, such as computers or mobile phones. In technology, there can be connection or processing problems that lead to disturbances in playback. As a result, audio and video signals, for example, are time-delayed, which can be noticeable and disturbing. Since short-term memory is needed, especially in […]
