Abstract As an interdisciplinary eld, hearing research combines scienti c and technical methods to gain new knowledge and understanding. Thereby modeling in an essential tool. Collected data from perceptual experiments is processed in logical structures to achieve a better understanding of the human hearing. The focus in this project is directed on modeling forced-choice experiments (specifically alternative forced choice AFC). The aim is to include the process of the experiment in the Auditory Modeling Toolbox (AMT) for Matlab and to test this experimental procedure with a model. In this work a binaural signal detection model described by [Breebaart et al., 2001a] is implemented and tested for various listening conditions. Finally, all AFC-functions are designed in such a way that they generally can be used for other models in the AMT.
