    • 3D audio as an information-environment: Manipulating perceptual significance for differentiation and pre-selection 

      Lennox, Peter P; Vaughan, John M; Myatt, Tony (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      Contemporary use of sound as artificial information display is rudimentary, with little 'depth of significance' to facilitate users' selective attention. We believe that this is due to conceptual neglect of 'context' or ...
    • Acoustic cues for 3-D shape information 

      Rocchesso, Davide (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      Three-dimensional resonators, such as cavities or rooms, affect the perceived timbral character of any sound source there enclosed. It is well understood how the resonator size, or the material of the enclosure, are conveyed ...

      A statistician (Hansen) and a media artist (Rubin) investigate the application of statistical methods and sound-design principles to the real-time sonification of Internet communications. This paper presents results from ...
    • Bliain le baisteach - sonifying a year with rain 

      Fernstrom, Mikael; Griffith, Niall; Taylor, Sean (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      In this paper the development of software for the creation of Bliain Le Baisteach is described. Over 77,000 datapoints were received from the Irish meteorological service. A neural network was designed and trained with ...
    • Directional quality of 3-D amplitude panned virtual sources 

      Pulkki, Ville; Karjalainen, Matti (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      When a listener is surrounded by multiple loudspeakers, some of which are located above and/or below him/her, an immersive threedimensional auditory display can be created with vector base amplitude panning (VBAP). In VBAP ...
    • Distance-based speech segregation in near-field virtual audio displays 

      Brungart, Douglas S; Simpson, Brian D (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      In tasks that require listeners to monitor two or more simultaneous talkers, substantial performance benefits can be achieved by spatially separating the competing speech messages with a virtual audio display. Although the ...
    • Ecological acoustics and the multi-modal perception of rooms: Real and unreal experiences of auditory-visual virtual environments 

      Larsson, Pontus; Vastfjall, Daniel; Kleiner, Mendel (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      An ecological approach to multimodal perception of virtual environments suggests that different perceptual mechanisms should cooperate in forming an impression of the complex surrounding. Traditionally, Virtual Environments ...
    • The effect of auditory rendering on perceived movement: Loudspeaker density and HRTF 

      Ballas, James A; Brock, Derek; Stroup, Janet; Fouad, Hesham (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      Until recently, multiple speaker systems for Virtual Environment (VE) applications were limited to a few front and rear speakers. Utilizing the Virtual Audio Server (VAS) with a Vector Base Amplitude Panning (VBAP) algorithm ...
    • Effect of increasing system latency on localization of virtual sounds with short and long duration 

      Wenzel, Elizabeth M (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      In a virtual acoustic environment, the total system latency (TSL) refers to the time elapsed from the transduction of an event or action, such as movement of the head, until the consequences of that action cause the ...
    • Effects of auditory icons and earcons on visual categorization: The bigger picture
