Topic: Age-related Changes in Auditory Processing and Perception
Abstract: Individual differences in auditory perception result from experience and injury, but also from the normal physiological changes that occur during development and aging. Children undergo a period of dynamic neurobiological development that parallels performance improvements on many psychoacoustic tasks. Older adults, even those without hearing loss, exhibit declines in auditory perception that coincide with poorer auditory system function and less precise neural synchrony. In this talk, I will discuss evidence for differences in auditory processing between children and adults who use cochlear implants. I will also describe studies in normal hearing adults that may support a relationship between age-related changes in the auditory periphery and challenges understanding speech in noisy listening environments.
Findings from these investigations encourage age-specific approaches to treatment of auditory perceptual impairments.
