Abstract:
Audio-visual virtual reality is a very useful tool when studying pedestrian perception of vehicles in street-crossing scenarios. It allows reproducible and safe experimental conditions and also allows for running experiments in different labs. However, as with any tool, it is vital to test the performance. As such, in this experiment we compared various acoustic simulations of approaching cars. For the comparison, we used two different Higher Order Ambisonics (HOA) rendering approaches (16 loudspeakers and 40 loudspeakers plus subwoofer) as well as a Wave Field Synthesis (WFS) approach (using more than 460 loudspeakers). The rendered vehicle scenes were recorded with an artificial head. In a listening test, participants evaluated these binaural recordings with regard to subjective attributes. In addition, the signals were analyzed using psychoacoustic metrics. The perceptual ratings and psychoacoustic metrics were compared between the different rendering methods. The results provide an insight into the perceptual similarities and differences between different dynamic auditory VR simulation approaches.
