      Cohen, Jonathan (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)

      Abel, Jonathan S; Foster, Scott (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Virtual audio displays control the apparent location of sound sources by applying left-ear and right-ear filters designed to mimic the acoustic properties of the human torso, head, and pinnae. These filters, called ...
    • MagicMikes - multiple aerial probes for sonification of spatial datasets 

      Grohn, Matti; Takala, Tapio (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      We present a method for sonification of data sets located in spatial environments in such a way that both individual point sources and overviews of larger data areas can be observed.
    • Dynamical resonances and synchronization of auditory stimuli and evoked reponses in multi-channel EEG 

      Mayer-Kress, Gottfried (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Perceptions of complex structures or other cognitive events are associated with synchronous oscillation of neural cell assemblies which take place in the 40 Hz domain and last for about 100 ms. We use EEG signals from 31 ...
    • LSL: A specification language for program auralization 

      Mathur, Aditya P.; Boardman, David B.; Khandelwal, Vivek (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The need for specification of sound patterns to be played during program execution arises in contexts where program auralization is useful. We present a language named LSL (Listen Speciikation Language) designed for ...
    • Design and evaluation of an auditory glance at algebra for blind readers 

      Stevens, R.D; Brewster, S.A; Wright, P.C; Edwards, A.D.N (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      An overview or glance is important in planning the reading process. Such a high-level view is not possible for a blind person when reading by listening. This paper describes the sonification of algebra notation to provide ...
    • The 'GUIB' spatial auditory display - generation of an audio-based interface for blind computer users 

      Crispien, Kai; Petrie, Helen (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      In order to provide access to graphical-based user interfaces (GUI's) for blind computer users, a screen-reader program system is under development which conveys the GUI into auditive and/or tactile form. The spatial ...
    • The importance of head movements for localizing virtual auditory display objects 

      Wightman, Frederic L; Kistler, Doris J (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      In most of our research we produce virtual sound sources by filtering stimuli with head-related transfer functions (HRTF's) measured from discrete source positions and present the stimuli to listeners via headphones. With ...
    • Perception of virtual auditory shapes 

      Hollander, Ari J.; Furness III, Thomas A. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Virtual environments may help us to understand and eventually extend the domain of auditory perception. The authors performed two experiments which verified the ability of subjects to recognize geometric shapes and ...
    • Task-oriented quantitative testing for synthesized 3-D auditory displays 

      Julig, Louise Frantzen; Kaiwi, Jerry L. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Current human machine interfaces in Navy systems which incorporate headphone listening fail to take full advantage of human binaural sensory processing capabilities. These interfaces can be improved by providing the ...
    • Using audio windows to analyze music 

      Cohen, Michael (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Alternative nonimmersive perspectives enable new paradigms of perception, especially in the context of frames-of-reference for musical audition and groupware. "maw," acronymic for multidimensional audio windows, is an ...
    • Sound localization in varying virtual acoustic environments 

      Zahorik, Pavel; Kistler, Doris J; Wightman, Frederic L (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
