      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 ...
    • For those who died: A 9/11 tribute 

      Quinn, Marty; Quinn, Wendy; Hatcher, Ben (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      For Those Who Died is a 6-minute dance and music tribute to those who died on 9/11. It premiered 9/11/2002 as part of a larger event entitled ``Reflections, A Gift to the Community'' that occurred at the Music Hall in ...
    • D'Groove: A haptic turntable for digital audio control 

      Beamish, Timothy; van de Doel, Kees; MacLean, Karon; Fels, Sidney (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      In this paper, we discuss the design and implementation of D'Groove, an intelligent Disc Jockey (DJ) system that uses a haptic turntable for controlling the playback of digital audio. We begin by describing the tasks of a ...
    • Household appliances control device for the elderly 

      England, David; Salces, Fausto J Sainz; Vickers, Paul (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      An evaluation of musical earcons was carried out to see whether they are an effective and efficient method of delivering information about household appliances to elderly people. A test was carried out to explore the ability ...
    • Identifying where you are in a room: Sensitivity to room acoustics 

      Shinn-Cunningham, Barbara; Ram, Suraj (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      In a spatial auditory display, reverberation provides a reliable cue for source distance, increases the subjective realism of the display, and improves the externalization of simulated sound sources. However, relatively ...
    • The IEM-cube 

      Zmolnig, Johannes; Ritsch, Winfried; Sontacchi, Alois (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Traditional multichannel-reproduction systems are mainly used for recreation of pantophonic sound elds. Fully periphonic reproduction has been limited by computational power to manipulate large numbers of audio-channels ...
