Bachelor Thesis of Klein, Simon

Nowadays, head-mounted displays (HMD) like the Oculus Rift or the HTC Vive allow an immersive experience of virtual environments even for the consumer market. To present a correct audio stimulus beside these visual reproductions loudspeaker-based reproduction methods can be used. In this thesis such loudspeaker-based reproduction method should be optimized in terms of computational efficiency by investigating the possibilities of simplifying or shortening the used filters. Furthermore the results of such an optimization will be investigation in terms of subjective audibility (i.e. a short listening experiment) and objective parameters (e.g. change in energy of the filters). Both the optimization and listening test can be coded in MATLAB using the ITA-Toolbox. Requirements - Programming skills (MATLAB) - Work independendly - Interest in the topic - Basics of Acoustics (e.g. ‘Einführung in die Akustik’)
