Investigations on the Impact of Listener Movement to the Perception of Source Directivity in Virtual Acoustic Environments
* Presenting author
An authentic and plausible simulation of virtual acoustic environments requires, among many other aspects, a thorough understanding of how a listener perceives the directivity of a sound source. State-of-the-art VR applications allow the user to explore a virtual scenario while walking around freely. We assume that the translation of the listener in the scene contributes to the understanding of the scene and the source directivity. The aim of the research is to examine this impact of listener translations to the perception more closely.In this contribution, we present a new test method to evaluate the perception using listener translation in virtual acoustic environments. The experiment was conducted with binaural real-time auralisation for tracked listener movements. As test conditions a free-field scenario and a simulated room were chosen. The derived results show, that the test method is suitable to determine the assumed perceptual influences.
