A virtual auditory environment for investigating the auditory signal processing of realistic sounds

Sylvain Emmanuel Favrot

Abstract

A loudspeaker-based virtual auditory environment (VAE) has been developed to provide a realistic versatile research environment for investigating the auditory signal processing in real environments, i.e., considering multiple sound sources and room reverberation. The VAE allows a full control of the acoustic scenario in order to systematically study the auditory processing of reverberant sounds. It is based on the ODEON software, which is state-of-the-art software for room acoustic simulations developed at Acoustic Technology, DTU. First, a MATLAB interface to the ODEON software has been developed. Afterwards, different multi-channel playback algorithms have been implemented in MATLAB in order to be able to present a succession of sounds through the VAE in a fast and efficient way. A set of both objective (physical) and subjective (perception-based) measures has been selected to validate the environment and assess its quality.
