Implementierung eines Modells zur Messung und Darstellung binauraler Lokalisation

Project

Accurate assessment of acoustic situations with respect to human sound localization may require an extensive effort. In order to obtain representative and insightful results, a minimum number of test persons is needed for subjective psychoacoustic evaluation . To circumvent this intensive process this work elaborates on a technical estimation of human sound localisation.

The goal of this student´s project is to implement an efficient software application that evaluates the human source localization in given acoustic situations. Using a functional model of binaural sound localization, the application should be able to create a graphical representation of the localization probability. As a main input, signals recorded by a dummy head, i.e. binaural signals, will be used. In terms of the model, a particular approach shall be selected from various existing models of human hearing in literature, and correspondingly modified or extended, if necessary.

The hereby created software serves as estimator of human sound localization, and can therefore not fully replace proper listening tests. However, it will be highly suitable to obtain and repeatable, quick and illustrative results if listening tests are not feasible.
