| Abstract: | Older adults, even with good audiometric thresholds, have more difficulty understanding speech in noisy environments than younger adults do. While there are several age-related changes that can affect communication, a significant body of evidence suggests that a loss of synchrony (i.e. degradation in temporal coding) in the auditory periphery can occur with age. To examine the consequences of this age-related change, several experiments using a jitter technique to simulate a loss of synchrony in an otherwise normal auditory system have been conducted. The results suggest two significant conclusions: A loss of synchrony can lead to a decrease in speech intelligibility in noise; as well, it is possible to simulate this neural aspect of auditory aging in healthy young ears using the jitter technique. |
