The primary objective of this thesis was to model primary school classroom noises in acoustic virtual reality of the three activity-based acoustic situations (ABAS): silent work, group work, and classroom break. In a subsequent step, the objective was to evaluate how close these noises resemble real-life primary school classroom soundscapes. Currently, there is no freely […]

Geometrical acoustics has been widely used to simulate sound propagation in various environments because it has a lower computational cost than wave-based numerical simulations. An acoustic radiosity model (Sparrowpy) with a tabulated BRDF extension, which discretises reflections into finite cones based on random incidence or bidirectional scattering coefficients, is compared to an alternative ARE-based implementation […]

Humans often miss otherwise obvious unexpected events when they are focused on a demanding task. This can occur in the auditory as well as visual domain – inattentional deafness and blindness, respectively. These phenomena can pose a danger in everyday life, such as not noticing a child crossing the street while focusing on other aspects […]
