      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 ...
    • 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 ...
    • 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 ...
    • Do location and context operate independently? 

      Lemmens, Paul M.C; de Haan, Ab; van Galen, Gerard P (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      To investigate if location and content operate independently, two experiments were carried out in which redundant auditory co–messages to a visual categorization task were manipulated to enable left and right ear only ...
    • 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 ...
    • ``Listenin'' to domestic enviroments from remote locations 

      Schmandt, Chris; Vallejo, Gerardo (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      This paper describes ListenIn, work in progress using audio as a monitoring medium, with emphasis on domestic environments inhabited by elder parents. The primary goal of this monitoring is to provide a continuous but ...
    • Parameters for auditory display of height and size 

      Cabrera, Densil; Tilley, Steven (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      The vertical localization, and vertical and horizontal spread, of auditory images was investigated using a vertical 5- loudspeaker array, with the noise-band signal spectrum, loudness level, number of active loudspeakers, ...
    • Optimizing the spatial configuration of a seven-talker speech display 

      Brungart, Douglas S; Simpson, Brian D (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Although there is substantial evidence that performance in multitalker listening tasks can be improved by spatially separating the apparent locations of the competing talkers, very little effort has been made to determine ...
    • Maximum listening speeds for the blind 

      Asakawa, Chieko; Takagi, Hironobu; Ino, Shuichi; Ifukube, Tohru (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
