| Abstract(in English) | The work has concentrated on improving the ability of audio systems to produce "images" of sound sources perceived by the listener. In short, we try to produce the illusion in a listener of being in a "virtual" acoustic environment which is entirely different from that of the space in which he (or she) is actually located. In particular we highlight the development of a very specific virtual imagine technique based on the "Stereo Dipole" which uses a pair of very closely spaced loudspeakers to produce virtual images. The major advance associated with this work is associated with the precise form of the acoustic field produced by the loudspeakers which makes it an ideal means for producing virtual images. There are many factors controlling the success of these systems, not least of which is the complex processing of acoustic signals that occurs in the auditory system of the listener. Topics addressed will include a description of the physical form of the acoustic fields produced by such imaging systems. We have introduced a spherical model to analyze the sound field around a listener in all computer simulations. On the other hand, many of the features of the performance of virtual acoustic imaging systems can be explained in terms of the known behavior of the human auditory system in localizing acoustic sources. In this paper, a model of binaural sound localization is applied to evaluate the ability to reproduce virtual sound fields based on the multi-channel recording and multiple virtual source technique. |
