Abstract
The augmented-reality virtual-diffusion system presented here aims to evaluate the comfort of a subject listening to a nearby speaker located in a room filled with a diffuse crowd. The main parameter to be studied is sound field diffusion and its relation to comfort. To this purpose a virtual diffusion system, based on electro acoustic transducers mounted on the walls, is employed to actively change the properties of the diffuse sound field. The augmented reality factor is introduced through the interaction of the virtual diffusion system with the acoustics of the room. The present paper presents a brief description of the approach chosen to implement the augmented-reality virtual-diffusion system. Diffusion measurements obtained with both virtual and real diffusers are compared. Results regarding auditory events location evoked by different sound fields and predictions from a cross-correlation-based binaural model employed to model these results are discussed. Initial results relative to comfort evoked by the different sound fields as well as a possible relation between auditory events location and listener comfort are discussed.
