Factors associated with individual differences in clinical measures of speech recognition among the elderly.

چکیده
In the present study, the speech-recognition performance of 50 subjects aged 63 to 83 years was measured for a wide range of materials (nonsense syllables, monosyllabic words, sentences) and listening conditions (presentation levels of 70 and 90 dB SPL, both in quiet and in a noise background). In addition to complete audiologic evaluations, measures of auditory processing (the Test of Basic Auditory Capabilities [TBAC], Watson, 1987) and cognitive function (Wechsler Adult Intelligence Scale-Revised [WAIS-R], and the Wechsler Memory Scale-Revised [WMS-R], Wechsler, 1981, 1987) were obtained from all subjects. Principal component analyses were applied to each of the three sets of measures (speech-recognition, auditory, and cognitive) prior to examining associations among the sets using canonical analyses. Two principal components captured most of the systematic variation in performance sampled by the set of 20 speech-recognition measures. Hearing loss emerged as the single largest factor associated with individual differences in speech-recognition performance among the elderly, accounting for 70-75% of the total variance in speech-recognition performance, with the measures of auditory processing and cognitive function accounting for little or no additional variance.

Factors affecting the recognition of reverberant speech by elderly listeners.
Elderly listeners have been shown to experience greater difficulty with speech understanding than young listeners. The greater difficulty with speech understanding in elderly listeners has been attributed, primarily, to their typical high-frequency sensorineural hearing impairment. However, not all of the observed difficulty can be accounted for by hearing thresholds, leaving the likelihood of ...

متن کاملCorrelation between Auditory Spectral Resolution and Speech Perception in Children with Cochlear Implants
Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
متن کاملReliability of Interaural Time Difference-Based Localization Training in Elderly Individuals with Speech-in-Noise Perception Disorder
Background: Previous studies have shown that interaural-time-difference (ITD) training can improve localization ability. Surprisingly little is, however, known about localization training vis-à-vis speech perception in noise based on interaural time difference in the envelope (ITD ENV). We sought to investigate the reliability of an ITD ENV-based training program in speech-in-noise perception a...
