Convolution with spatial room impulse responses (RIRs) is often used to create realistic auralisations. The technique can be combined with spatial interpolation to create navigable virtual environments. This paper reports the preliminary results of an experiment designed to assess the impact of various interpolation parameters on perceived auditory source stability under various auralisation conditions. Participants freely explored a virtual scene while listening to a 3rd order Ambisonic RIR auralisation over headphones equipped with a tracked head-mounted display. They were asked to rate source stability under various conditions of RIR grid density, interpolation panning method, and room acoustics. A preliminary analysis of the results is presented.
