      In this paper, we select the application domain of earthquake engineering for utility of sonification, where signals are of random frequency and amplitude content. In particular, we focus on the response of structures to ...
    • Analytic listening: A case study of radio production 

      Barbour, J. (Georgia Institute of TechnologyInternational Community for Auditory Display, 2004-07)
      Radio is the ultimate auditory display: all information is conveyed aurally to a listener. Sound from a radio invokes visual images in the imagination of a listener, the theatre of the mind. Listening to a radio voice ...
    • Interacting with sound: An interaction paradigm for virtual auditory worlds 

      Roeber, N.; Masuch, M. (Georgia Institute of TechnologyInternational Community for Auditory Display, 2004-07)
      The visual and the auditory field of perception respond on different input signals from our environment. Thus, interacting with worlds solely trough sound is a very challenging task. This paper discusses methods and ...
    • Designing sound: Towards a system for designing audio interfaces using timbre spaces 

      Gray, P.; Brewster, S.; Nicol, C. (Georgia Institute of TechnologyInternational Community for Auditory Display, 2004-07)
      The creation of audio interfaces is currently hampered by the difficulty of designing sounds for them. This paper presents a novel system for generating and manipulating non-speech sounds. The system is designed to generate ...
    • Individual differences, cognitive abilities, and the interpretation of auditory graphs 

      Walker, Bruce N.; Mauney, Lisa M. (Georgia Institute of TechnologyInternational Community for Auditory Display, 2004-07)
      Auditory graphs exploit pattern recognition in the auditory system, but questions remain about the relationship between cognitive abilities, demographics, and sonification interpretation. Subjects completed a magnitude ...
    • How long does it take to identify everyday sounds 

      Guillaume, A.; Drake, C.; Blancard, C.; Chastres, V.; Pellieux, L. (Georgia Institute of TechnologyInternational Community for Auditory Display, 2004-07)
      Previous studies of alarm design have concluded that the faster a mental representation of the cause of the alarm is activated, the quicker the adapted reaction. In order to select sounds that are quick to identify, an ...
