The propagation of sound can be effectively and accurately modelled using geometrical simulation techniques. Traditional techniques, such as ray tracing and radiosity, generate energy decay responses that characterize acoustic interactions within specific environments. These responses can be transformed into impulse responses based on room acoustic models, facilitating a realistic sound reproduction. Filter synthesis approaches for […]

The optoacoustic effect describes the creation of sound by means of radiation, mainly through the effects of differing temperature inside a target material. The full physical mechanisms behind the phenomenom are currently being studied, with the goal of using the effect among other things to the advantage of creating sound perception in humans directly at […]

Children spend much of their day in classrooms where understanding speech is often challenged by background noise . This thesis reanalyzes data from two studies to investigate how efficiently primary school children listen in classroom settings, using the metrics "Direct Listening Efficiency" , "Linear Integrated Speed–Accuracy Score" , "Balanced Integration Score" and "Inverse Efficiency Score" […]
