The simulation of audio-visual performance is despite technological advancements still a challenging task which usually requires researchers to simplify problems in order to reduce computational complexity, sacrificing both auditory and visual fidelity. This raises the question as to what degree a model can be simplified without a noticable loss of quality. In order to analyze the impact of varying sound sources and visual stimuli on users‘ perception, listening experiments are performed in Virtual Reality (VR) in which participants describe their impression of scenes using a number of attributes.

The goal of this work is to create a framework in which such experiments can be easily designed and efficiently analyzed. In order to achieve this an interface between Unreal Engine (UE) and Matlab is created where Matlab serves both as a data capturing tool and as an application that can be used to control different parameters of listening experiments. As a proof of concept a listening experiment will be designed in which participants explore a VR model of the IHTA Park in three different levels of detail and provide a vocabulary to describe and rate their experience.
