Topic: Age-related Differences in Auditory Grouping and Segregation
The abilities to group sounds together based on shared acoustic features and to separate target sounds from background are important for speech perception in noise. Age-related hearing loss deteriorates these abilities, leading to a degradation in speech perception in noise. Few studies have aimed to tease apart the independent effects of age and hearing loss on changes in auditory grouping and segregation. Little is known about how age uniquely contributes to the degradation of auditory grouping and segregation. We evaluated these abilities in clinically normal-hearing listeners from 20-84 years of age. In this talk, I will share findings on age-related differences in a monaural modulation detection interference task and a binaural interference task that both assess grouping and segregation.
