Room acoustic simulations usually assume the acoustic impedance of surfaces to be independent from wave incidence angle - in other words locally reacting. For most materials this is a valid assumption. Some porous absorber structures are, however, non-locally reacting: Their surface impedance expresses a dependence on the direction of an incident wave - more exactly […]

Adequate room acoustic conditions are crucial for creating comfortable communication, learning, or working environments. While acoustic simulations are an established tool for the prediction of the acoustic conditions in a room, the input data describing the acoustic properties of the surfaces and objects in rooms comes with uncertainties. In this thesis work, standardized and non-standardized […]
