Aspects of Auralization in Binaural Room Simulation

Abstract

Binaural room simulation is a method to accomplish listening in spaces which only exist in the form of computer models. The simulation process comprises two stages, namely, sound-field modelling and auralization. A spatial map of virtual sound sources, the interface between the two stages, represents a complete symbolic description of the auditory environment to be simulated. Psychoacoustic assessment of the validity of this symbolic description is reported, and details of the auralization procedure are discussed. As auralization is based on binaural technology, measurement of head transfer functions (HTF) is required. To this end, an appropriate measurement and equalization technique and an auditorily adequate compression algorithm for HTFs are described. Some discussion is devoted to the perceptual effect of a-priori reverberation in the input signals to the binaural room simulation process.
