    Evaluating the spatial sonification of the molecular structures of amino acids using multiple concurrently sounding sources
    (Georgia Institute of Technology, 2021-06) Liu, Danyi ; van der Heide, Edwin ; Leiden Institute of Advanced Computer Science
    We have designed an interactive form of sonification in which the listener navigates through the molecular structures of amino acids over the network of carbon atoms. We use pitch and density as the two main features for the sound design of the four common chemical elements (H, C, N, O).We use multiple concurrently sounding sources to spatially sonify the atoms around a certain carbon atom of the amino acids. The main goal of this paper is to evaluate this sonification approach. We cover the design, execution and evaluation of two separate cycles of experiments that aim to evaluate our sonification approach and get insight in factors that may influence the individual performance of the concurrently sounding source identification and localization.

    An audio mixer based on 3D acoustical simulation of architectural models
    (Georgia Institute of Technology, 2009-05) Rindel, J.H ; Christensen, C.L. ; Odeon
    The acoustic illusion of music being performed in any room, being virtual or real, is possible with today’s advanced room acoustic software, Odeon. Recently, a music CD has been released with the simulated acoustics of the famous Hagia Sophia in Istanbul, although the recordings were originally made in an anechoic room. The quality and realism of the 3D sound is believed to be unparalleled. The acoustic simulation technique has also been applied for the simulation of a complete symphony orchestra using multi-source-auralisation and an integrated mixing of the sound from all the instruments. The room acoustic software Odeon was originally developed at the Technical University of Denmark with the purpose of making acoustic simulations as a tool for the design of concert halls and other acoustic venues. The simulation technique is based on theoretical models and approximations of the physical behaviour of sound in rooms such as reflection, absorption, scattering, and diffraction. The directional characteristic of the sound sources is also taken into account. The presentation will include music examples combined with the acoustics of a reconstructed Roman theatre, a Byzantine church, and a new concert hall.

    Exploratory Sound Analysis: Sonifying Data About Sound
    (International Community for Auditory Display, 2008-06) Ferguson, Sam ; Cabrera, Densil ; University of Sydney. Acoustics Research Laboratory, Faculty of Architecture, Design and Planning
    Sound is commonly analysed subjectively by listening to it. However, when we want to analyse a sound objectively, we often switch domains, and change to visual or numerical displays. While it is likely that, generally speaking, the visual sense dominates other senses, when the data being explored are sound the question naturally arises as to whether these data may be statistically represented in that same domain. This paper describes and demonstrates a general scheme for building statistical representations of sound that exist entirely within the auditory domain, and use the original audio data to present descriptive data.

    Sonified Aerobics - Interactive Sonification of Coordinated Body Movements
    ( 2011-06) Hermann, Thomas ; Zehe, Sebastian ; Biefeld University. Center of Excellence in Cognitive Interaction Technology. Ambient Intelligence Group
    This paper introduces a new hard-/ and software system for the interactive sonification of sports movement involv- ing arm- and leg movements. Two different sonifications are designed to convey rhythmical patterns that become au- ditory gestalt so that listeners can identify features of the underlying coordinated movement. The Sonification is de- signed for the application to enable visually impaired users to participate in aerobics exercises, and also to enhance the perception of movements for sighted participants, which is useful for instance if the scene is occluded or the head pos- ture is incompatible with the observation of the instructor or fitness professional who shows the practices in parallel. Furthermore, the system allows to monitor fine couplings in arm/leg coordination while jogging, as auditory feedback may help stabilizing the movement pattern. We present the sensing system, two sonification designs, and interaction examples that lead to coordination-specific sound gestalts. Finally, some qualitative observations are reported from the first uses of the prototype.

    Localization of a moving virtual sound source in a virtual room, the effect of a distracting auditory stimulus
    (Georgia Institute of Technology, 2002-07) Groehn, M. ; Helsinki University of Technology. Telecommunications Software and Multimedia Laboratory
    An audio localization test of moving virtual sound sources was carried out in a spatially immersive virtual environment, using loudspeaker array with vector based amplitude panning for reproduction of sound sources. Azimuth and elevation error in localization was measured. In this experiment the main emphasis was to explore the effect of a distracting auditory stimulus. Eight subjects accomplished a set of localization tasks. In these tasks they perceived the azimuth more accurately than the elevation. The distracting auditory stimulus decreased the localization accuracy. There was large variation between the subjects. The median error in azimuth for the most inaccurate subject was approximately twice as much as for the most accurate subject. The amount of the localization blur was dependent on angular distance from virtual sound source position to the nearest loudspeaker. The localization blur increased while the angular distance increased. Results of this experiment were compared with the results achieved in our previous experiment without the distracting stimulus.

    A sonification experience to portray the sounds of portuguese consumption habits
    (Georgia Institute of Technology, 2019-06) Seica, Mariana ; Martins, Pedro ; Roque, Licinio ; Cardoso, F. Amilcar ; University of Coimbra. Department of Informatics Engineering
    The stimuli for consumption is present in everyday life, where major retail companies play a role in providing a large range of products every single day. Using sonification techniques, we present a listening experiment of Portuguese consumption habits in the course of ten days, gathered from a Portuguese retail company. We focused on how to represent this time-series data as a musical piece that would engage the listenerメs attention and promote an active listening attitude, exploring the influence of aesthetics in the perception of auditory displays. Through a phenomenological approach, ten participants were interviewed to gather perceptions evoked by the piece, and how the consumption variations were understood. The tested composition revealed relevant associations about the data, with the consumption context indirectly present throughout the emerging themes: from the idea of everyday life, routine and consumption peaks to aesthetic aspects as the passage of time, frenzy and consumerism. Documentary, movie imagery and soundtrack were also perceived. Several musical aspects were also mentioned, as the constant, steady rhythm and the repetitive nature of the composition, and sensations such as pleasantness, satisfaction, annoyance, boredom and anxiety. These collected topics convey the incessant feeling and consumption needs which portray our present society, offering new paths for comprehending musical sound perception and consequent exploration.

    Creating functional and livable soundscapes for peripheral monitoring of dynamic data
    (Georgia Institute of Technology, 2004-07) Mauney, Bradley S. ; Walker, Bruce N. ; Georgia Institute of Technology. School of Psychology ; Georgia Institute of Technology. Sonification Lab ; Brazil, Eoin
    Sonifications must be studied in order to match listener expectancies about data representation in the form of sound. In this study, a system was designed and implemented for dynamically rendering sonifications of simulated real-time data from the stock market. The system read and parsed the stock data then operated unit generators and mixers through a predefined sound mapping to create a `soundscape' of complementary ecological sounds. The sound mapping consisted of a threshold-based model in which a percentage change in price value was mapped to an ecological sound to be played whenever that threshold or gradient had been reached. The system also provided a generic mechanism for fading and transitioning between gradients. The prototype system was presented to stock trader test subjects in their work-listening environment for evaluation as a stand-alone system and in comparison to their preferred tools.

    Investigating the effect of earcon and speech variables on hybrid auditory alerts at rail crossings
    (Georgia Institute of Technology, 2021-06) Nadri, Chihab ; Lee, Seul Chan ; Kekal, Siddhant ; Li, Yinjia ; Li, Xuan ; Lautala, Pasi ; Nelson, David ; Jeon, Myounghoon ; Virginia Tech.

    Despite rail industry advances in reducing accidents at Highway Rail Grade Crossings (HRGCs), train-vehicle collisions continue to happen. The use of auditory displays has been suggested as a countermeasure to improve driver behavior at HRGCs, with prior research recommending the use of hybrid sound alerts consisting of earcons and speech messages. In this study, we sought to further investigate the effect of auditory variables in hybrid sound alerts. Nine participants were recruited and instructed to evaluate 18 variations of a hybrid In-Vehicle Auditory Alert (IVAA) along 11 subjective ratings. Results showed that earcon speed and pitch contour design can change user perception of the hybrid IVAA. Results further indicated the influence of speech gender and other semantic variables on user assessment of HRGC IVAAs. Findings of the current study can also inform and instruct the design of appropriate hybrid IVAAs for HRGCs.

    Sonification of a real-time physics simulation within a virtual environment
    (Georgia Institute of Technology, 2012-06) Perkins, Rhys ; Anglia Ruskin University. Dept. of Music and Performing Arts
    There has been an increasing amount of research in utilising 3D virtual environments as a core component of interactive sonifications. While showing considerable potential for their ability in producing both real-time visualisation and sound, they often come with constraints as a result of their design decision processes. This paper presents developments of a prototype that have arisen out of my attempts to address some of the issues involved in bringing sonification to a wider audience through a universal metaphor. These new additions allow for an intuitive, elementary introduction into to the world of auditory display, while providing a more flexible and immersive environment for composition and sound design.
