Auditory scene analysis, a concept created by Albert Bregman, is a process in which the auditory system takes the mixture of sound that it derives from a complex natural environment and sorts it into packages of acoustic evidence in which each package probably has arisen from a single source of sound. This grouping helps pattern recognition not to mix information from different sources. (Source - http://www.psych.mcgill.ca/labs/auditory/introASA.html)
