AB  - Within the project VIA2mobiL, we developed signal processing algorithms and methods for a dynamic headphone-based binaural synthesis, with a special focus on radio communication in mobile control centers. Our aim was to achieve a better speech intelligibility in radio communication through the binaural presentation of a conversation scene with several separately locatable interlocutors. In our investigations, a method for determining word recognition rates and 50 % speech reception thresholds (SRTs) was developed on the basis of the methodology of the Oldenburg sentence test (OLSA). By means of conducted listening experiments, we examined whether the application of a dynamic binaural synthesis results in a gain in speech intelligibility if compared to monophonic or stereophonic reproduction, in particular for TETRA-coded speech. We present the study design and the results of the experiments which show that considerably higher word recognition rates can be achieved with a binaural synthesis compared to a monophonic and stereophonic reproduction at the same level, for both TETRA-coded and uncoded speech. Furthermore, significantly lower 50 % SRTs in the presence of noise were observed for 3D audio compared to a monophonic and stereophonic reproduction.
