Perception and rendering of three-dimensional surround sound
نویسنده
چکیده
Recent technological trends facilitate threedimensional stereophony. To this day, no internationally agreed standard for three-dimensional sound reproduction exists. Fundamental research is needed to define basic system parameters and ensure compatibility between different formats. Background in spatial audio perception, stereophonic audio reproduction, and automatic channel format conversion is summarized. The current state of the art in sound processing for loudspeaker playback and objective evaluation of sound field quality features is discussed based on three selected papers. Future research necessary to cope with stereophonic reproduction using arbitrary loudspeaker arrangements is motivated and outlined.

متن کاملVirtual Reality Motion Parallax with the Facebook Surround-360 using a Depth Augmented Stereo Panorama
Recent interest in virtual reality has led to the development of 360-degree media platforms. In general, 360-degree images or videos can be observed using a head-mounted display (HMD) which tracks head position and renders images for each eye with low latency. Three-dimensional scenes can be portrayed by such displays by incorporating depth cues important to human perception of 3D position. Suc...
متن کاملRough-Neuro Approach to Testing Influence of Visual Cues on Surround Sound Perception
The paper aims at revealing in which way and how the surround sound interferes or is associated with the visual context. Such parameters as distance, angle or level of sound source were tested with and without video image presence in the screen. For that purpose subjective testing was applied. Processing of the obtained results has been done on the basis of the combined neural network and rough...

Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...
