background :older adults with cerebrovascular accident (cva) show evidence of auditory and speech perception problems. in present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds. methods : concurrent auditory seg...

The peripheral and central auditory systems undergo tremendous changes with normal aging. In this review, we focus on the effects of age on processing complex acoustic signals (such as speech and music) amid other sounds, which requires a set of computations known as auditory scene analysis. Auditory scene analysis is the process whereby the brain assigns parts of the acoustic wave derived from...

Computational audition has always been a subject of multiple theories. Unfortunately very few place audition in the grander scheme of perception, and even fewer facilitate formal and robust definitions as well as efficient implementations. In our work we set forth to address these issues. We present mathematical principles that unify the objectives of lower level listening functions, in an atte...

Music can evoke powerful emotions in listeners. Here we provide the first empirical evidence that the principles of auditory scene analysis and evolutionary theories of emotion are critical to a comprehensive theory of musical emotion. We interpret these data in light of a theoretical framework termed "the source dilemma hypothesis," which predicts that uncertainty in the number, identity or lo...
