Aging and Auditory Temporal
Processing
Sandra Gordon-Salant, Ph.D.
The University of Maryland, College Park, MD
As people age, their perception of rapid changes
in acoustic signals may decline. These age-related alterations in auditory
temporal processing have been observed for speech and non-speech signals
presented in isolation or within a sequence. The range of performance of
older listeners on auditory temporal processing tasks in which stimulus
duration or presentation rate is the variable will be discussed, as well
as implications of findings for older listeners' perception of temporally
altered speech signals.
The Aging Ear: Speech \ in Older
Adults
Judy R. Dubno, Ph.D.

Department of Otolaryngology-Head and Neck Surgery, Charleston, SC
As part of a large, ongoing study of age-related
hearing loss in humans and animals, audiometric data, including several
measures of speech recognition, have been obtained from more than 600 human
subjects over the age of 60 years. Some measures were repeated every 2-3
years over a 15-year period. Here, we report on age-related and gender-related
changes in speech recognition and their association with changes in pure-tone
thresholds and other audiometric findings. Work supported by the NIH.
Hearing-Aid Outcome Measures
in Older Adults
Larry E. Humes, Ph.D.
Department of Speech and Hearing Sciences
Indiana University, Bloomington, IN
In this presentation, recent research that
has identified several factors affecting hearing-aid outcome, and representative
measures of each dimension, will be identified. Next, research on the stability
of these outcome measures over time will be reviewed. Finally, variables
predictive of individual differences in performance on each of the outcome
dimensions will be examined. (Work supported, in part, by the NIA).
Understanding Age-Related Hearing
Loss Through Epidemiology
George Gates, M.D.
Department of Otolaryngology-HNS

Although nearly all people experience some degree of hearing decrement
with age, there is wide variation in the rate, type, and degree of impairment.
This variability suggests that non-uniform processes are involved. Our
observations of age-related hearing loss in the Framingham Heart Study
Cohort and Offspring suggest that strial presbycusis is an important factor
and that the strial pattern of loss is hereditary, more dominant in women,
and affected by cardiovascular disorders. Central auditory performance
also declines with age and is strongly affected by disorders causing dementia,
in particular Alzheimer's dementia. One test of central auditory function,
the Synthetic Sentence Identification with Ipsilateral Competing Message
is sensitive to the presence of dementia and in some cases may be abnormal
years before the dementia is diagnosed.
