A B S T R A C T Introduction:We investigated differential role of cortical and subcortical regions in verbal and non-verbal sound processing in ten patients who were native speakers of Persian with unilateral cortical and/or unilateral and bilateral subcortical lesions and 40 normal speakers as control subjects. Methods: The verbal tasks included monosyllabic, disyllabic dichotic and diotic tas...

Recent activation and electrophysiological studies have demonstrated that sound recognition and localization are processed in two distinct cortical networks that are each present in both hemispheres. Sound recognition and/or localization may be, however, disrupted by purely unilateral damage, suggesting that processing within one hemisphere may not be sufficient or may be disturbed by the contr...

Modern music production systems provide a plethora of sound resources, e.g. hundreds or thousands of sound patches on a synthesizer. The more the number of available sounds grows, the more difficult it becomes for the user to find the desired sound resource for a particular purpose, thus demanding for advanced retrieval techniques based on sound classification. This paper gives a short survey o...

Cochlear implants are devices designed to provide a measure of hearing to the deaf. Most deaf individuals have lost the ability to translate sound into the patterns of electric activity normally present on the 30,000 fibers of the auditory nerve. Because these patterns of activity are the inputs to the brain that result in sound sensation, cochlear implants deliver electric stimuli to these fib...

High-quality electret microphones and single-chip processors are economical enough to be used in large numbers. This latitude opens opportunities for dynamic source location and sound capture with spatial selectivity in three dimensions, This report discusses algorithms for matched-filter processing of microphone arrays and for coordinate tracking of moving talkers. A prototype conferencing sys...

We propose a novel model-concept of selective sound segregation based on Auditory Scene Analysis and then describe implementation of a prototype model for selectively segregating a target musical instrument sound from the mixed sound of various musical instruments. This model is extended from our previously proposed model of segregating two acoustic sources (Unoki and Akagi, Speech Communicatio...
