Abstract

To be a successful participant in a single conversation during difficult listening conditions, the listener has to segregate incoming sounds into separate conversations and focus on the conversation in which he or she is engaged, a skill commonly referred to as concurrent sound segregation. Research has shown that the decline in speech perception in noise in individuals with hearing impairment is greater than predicted based on hearing sensitivity levels alone; hence peripheral hearing loss by itself cannot account for the observed difficulties with auditory segregation skills. Indeed, some individuals with normal hearing also complain of difficulties understanding speech in complex listening conditions. Finally, attention of the listener plays an important role in concurrent sound segregation and changes in attentional skills due to aging and hearing status may alter sound segregation abilities.
