This study describes a binaural machine hearing system that is capable of performing auditory stream segregation in scenarios where multiple sound sources are present. The process of stream segregation refers to the capability of human listeners to group acoustic signals into sets of distinct auditory streams, corresponding to individual sound sources. The proposed computational framework mimic...

Auditory scene analysis is critical for complex auditory processing. We study auditory segregation from the neural network perspective, and develop a framework for primitive auditory scene analysis. The architecture is a laterally coupled two-dimensional network of relaxation oscillators with a global inhibitor. One dimension represents time and another one represents frequency. We show that th...

BACKGROUND This study assessed the relationship between working memory capacity and auditory stream segregation by using the concurrent minimum audible angle in children with a diagnosed auditory processing disorder (APD). METHODS The participants in this cross-sectional, comparative study were 20 typically developing children and 15 children with a diagnosed APD (age, 9-11 years) according t...

Auditory stream segregation refers to the perceptual grouping of sounds, to form coherent representations of objects in the acoustic scene, and is a fundamental aspect of hearing and speech perception. The perceptual segregation of simple interleaved tone sequences has been studied in humans and European starlings (Sturnus vulgaris) using sequences of 2 alternating tones differing in frequency ...

Auditory stream segregation is know as a process whereby sound elements are separated and integrated into some perceptual objects as a coherent whole, in the auditory scene analysis. Such a perceptual faculty is considered to be dependent on some factors in sounds such as similarity, good continuation, common fate, disjoint allocation, closure, and so on. For example, when we listen to fast alt...

Our previous research with adults suggests that pre-attentive (bottom-up) brain processes govern auditory stream segregation [Sussman et al., 1998. Brain Res. 789, 130--138; Sussman et al., 1999. Psychophysiology 36, 22--34; Winkler et al., submitted for publication]. We investigated whether the pre-attentive mechanisms underlying auditory stream segregation operate similarly in school-aged (7-...

Auditory stream segregation refers to a segregated percept of signal streams with different acoustic features. Different approaches have been pursued in studies of stream segregation. In psychoacoustics, stream segregation has mostly been investigated with a subjective task asking the subjects to report their percept. Few studies have applied an objective task in which stream segregation is eva...
