      Practical applications for auditory virtual environments (AVEs) are ever increasing. The achievable quality of AVEs has reached a level, where realworld problems can often be solved in a convenient way by using AVEs, meaning ...
    • Perceptual structure of everyday sounds: A multidimensional scaling approach 

      Bonebright, Terri L (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      The present study was designed to provide insight into the perceptual structure of everyday sounds. A large stimulus set of 74 sounds was used to gather sorting data, attribute ratings, and acoustic measurements for analysis ...
