The purpose of this presentation is to introduce to the NDE community an empirical modeling technique which has been under development during the past thirteen years and applied particularly to many problem areas in the last five. The application of interest to today's audience is that of classification of flaw geometry from ultrasonic signals. Disciplines Materials Science and Engineering | St...

In echolocating bats, the primary cue for determining distance to a target is the interval between an emitted orientation sound and its echo. Whereas frequency is represented by place in the bat cochlea, no anatomical location represents of primary range. Target range is coded by the time interval between grouped discharges of primary auditory neurons in response to both the emitted sound and i...

All sound separation systems based on perception assume a bottom-up or Marr-like view of the world. Sound is processed by a cochlear model, passed to an analysis system, grouped into objects, and then passed to higher level processing systems. The information flow is strictly bottom up, with no information flowing down from higher level expectations. Is this the right approach? This paper summa...

Short-term Time Structure of Cochlear Filtered Sound Leslie S. Smith CCCN, Dept. of Computing Science and Mathematics, University of Stirling Stirling FK9 4LA, Scotland. Abstract Auditory modelling uses the architecture of the auditory system to guide early sound processing. The advantage of this approach is (i) timeresolution is better and (ii) many bandpassed channels are available and can be...

There has been much debate over whether music can convey extra-musical meaning. The experiments presented here investigated whether low level musical features, specifically the timbre of a sound, have a direct access route to meaningful representations. Short musical sounds with varying timbres were investigated with regard to their ability to elicit meaningful associations, and the neural mech...

In this paper we describe and analyze The Argus Project, a sound installation involving the real-time processing and spatialized projection of sound sources from beneath a pond’s surface. The primary aim of The Argus Project is to project the natural sound sources from below the pond’s surface while tracking the changes in the environmental factors above the surface so as to map this data onto ...

Title of dissertation: NEURAL BASIS AND COMPUTATIONAL STRATEGIES FOR AUDITORY PROCESSING Mounya Elhilali, Doctor of Philosophy, 2004 Dissertation directed by: Professor Shihab A. Shamma Department of Electrical and Computer Engineering Our senses are our window to the world, and hearing is the window through which we perceive the world of sound. While seemingly effortless, the process of hearin...

Speech communication involves integration and coordination of sensory perception and motor production, requiring precise temporal coupling. Beat synchronization, the coordination of movement with a pacing sound, can be used as an index of this sensorimotor timing. We assessed adolescents' synchronization and capacity to correct asynchronies when given online visual feedback. Variability of sync...
