Distance Perception in Loudspeaker-Based Room Auralization

Authors: Favrot, Sylvain; Buchholz, Jörg M.

AES Convention 127 · Paper 7854 · October 2009

Abstract

A loudspeaker-based room auralization (LoRA) system has been recently proposed which efficiently combines modern room acoustic modeling techniques with high-order Ambisonics (HOA) auralization to generate virtual auditory environments (VAEs). The reproduction of the distance of sound events in such VAE is very important for its fidelity. A direct-scaling distance perception experiment was conducted to evaluate the LoRA system including the use of near-field control (NFC) for HOA. Experimental results showed that (i) loudspeaker-based auralization in the LoRA system provides similar distance perception to that of the corresponding real environment and that (ii) NFC-HOA provides a significant increase in the range of perceived distances for near sound sources as compared to standard HOA.
