    • Effect of beacon sounds on navigation performance in a virtual reality environment 

      Walker, Bruce N.; Lindsay, Jeff (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Navigating without vision can be quite a daunting task. This study details an auditory interface to deal with this situation and then describes initial validation experiments. Ss were assigned to conditions with differing ...
    • Evaluating soundscapes as a means of creating a sense of place 

      Turner, Phil; McGregor, Iain; Turner, Susan; Carroll, Fiona (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      We report an empirical study into the creation of, and response to, a soundscape of a computer centre. We contrast the use of presence questionnaires, as means of assessing the sense of being-there, against a more ...
    • Extending SMIL with 3D audio 

      Pihkala, Kari; Lokki, Tapio (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      This paper describes how SMIL can be extended to support 3D audio in a similar fashion than AABIFS does it for MPEG-4. The SMIL 2D layout is extended with an extra dimension to support a 3D space. New audio elements are ...
    • Extracting significant features from the HRTF 

      Raykar, Vikas C; Duraiswami, Ramani; Davis, Larry; Yegnanarayana, B (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      The Head Related Transfer Function (HRTF) characterizes the auditory cues created by scattering of sound off a person's anatomy. While it is known that features in the HRTF can be associated with various phenomena, such ...
    • Focalisation on the temporal context of complex sequences 

      Guillaume, Anne; Drake, Carolyn (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Studies of the perception of sound sequences indicate the existence of an optimal processing rate [1]: sequences in which sound events occur at rates within this range are processed in more depth than events within faster ...
