N2 - 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 is 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 intelligibility thresholds 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 compared to monophonic or stereophonic reproduction.We present the study design and the results of the experiments. They show that up to 44 % and 9 % higher word recognition rates can be achieved with a binaural synthesis compared to a monophonic and stereophonic reproduction at the same level. A similar increase in speech intelligibility/word recognition rate can also be observed for TETRA-coded speech. The threshold, in terms of level, for a speech intelligibility of 50 % in noise is approx. 15 dB and 13 dB below the threshold of monophonic and stereophonic reproduction.
