Title: Effects of Age on Within-Channel and Across-Channel Temporal Processing and Relationship to Speech Perception in Noise
Speaker: Varsha Mysore Athreya, PhD Student, SLHS
Abstract: Age-related changes in the auditory system can lead to difficulty perceiving speech in noise (SIN). Temporal processing plays a vital role in the perception of SIN, evidenced in prior behavioral studies. There are two mechanisms of temporal processing – within-channel, which is mediated by peripheral and central involvement of the auditory system, and across-channel, primarily involving the central auditory system. Animal studies suggest that with age, there are peripheral (loss of hair cells, cochlear synaptopathy) and central changes (down-regulation of inhibition). In this study, we sought to understand the relative contributions of within-channel and across-channel temporal processing mechanisms to speech perception in noise in individuals with near-normal hearing sensitivity as a function of age. In this talk, I'll be going over our preliminary data from subjects in a wide age range (18-70 years) and future goals.
