Listener Auditory Perception Enhancement using Virtual Sound Source Design for 3D Auditory System

Auditory Perception and Spatial (3D) Auditory Systems

In order to enable the user of a virtual reality system to be fully immersed in the virtual environment, the user must be presented with believable sensory input. Although the majority of virtual environments place the emphasis on visual cues, replicating the complex interactions of sound within an environment will benefit the level of immersion and hence the user’s sense of presence. Three dim...

An Auditory System Modeling in Sound Source Localization

Sound localization of the auditory system is useful in the industrial and military applications such as game, sonar, sound quality measurement. Two main key features that the auditory system utilizes for sound source localization are interaural intensity differences (IID’s) and interaural time differences (ITD’s). Both become the cues for the estimation of the elevation and azimuth of the sound...

Auditory Display of Sound Source Distance

Although the majority of research on spatial sound reproduction has concentrated on the directional components of source location, it is clear that full 3-dimensional rendering also requires an understanding of how to reproduce sound source distance. This article reviews and describes recent psychophysical research on distance perception of sound sources, with emphasis on how various acoustical...

Authoring of 3D virtual auditory Environments

Auditory authoring is an essential component in the design of virtual environments and describes the process of assigning sounds and voices to objects within a virtual 3D scene. In a broader sense, auditory authoring also includes the definition of dependencies between objects and different object states, as well as timeand user-dependent interactions in dynamic environments. Our system unifies...
