In this paper the interactive approaching motion towards a virtual loudspeaker created with dynamic binaural synthesis is subject to research. A realization based on a given set of measured binaural room impulse responses (BRIRs) was rated as plausible by all participants in a previous experiment. In this study the same BRIR-data is systematically simplified to investigate the consequences for the perception. This is of interest in the context of position-dynamic reproduction, related interpolation and extrapolation approaches as well as attempts of parameterization. The potential of inaudible data simplification is highly related to the human sensitivity to position-dependent changes in room acoustics. The results suggest a high potential for simplification, while some kinds of BRIR-impairment clearly affect the plausibility.
