“…Listeners with hearing loss (both young and old) also demonstrated poorest performance among the selective time-compression conditions for STC of consonants. This finding is in agreement with previous results showing that listeners with hearing loss have substantial difficulty perceiving consonant place if transition duration or burst duration is reduced (Dubno et al, 1987;Schum & Collins, 1990;Turner et al, 1997). Time compression of consonant segments may also have altered the relative-amplitude cue for consonant perception that is used by listeners with hearing loss (Hedrick, Schulte, & Jesteadt, 1995).…”

Older people frequently show poorer recognition of rapid speech or time-compressed speech than younger listeners. The present investigation sought to determine if the age-related problem in recognition of time-compressed speech could be attributed primarily to a decline in the speed of information processing or to a decline in processing brief acoustic cues. The role of the availability of linguistic cues on recognition performance was examined also. Younger and older listeners with normal hearing and with hearing loss participated in the experiments. Stimuli were sentences, linguistic phrases, and strings of random words that were unmodified in duration or were time compressed with uniform time compression or with selective time compression of consonants, vowels, or pauses. Age effects were observed for recognition of unmodified random words, but not for sentences and linguistic phrases. Analysis of difference scores (unmodified speech versus time-compressed speech) showed age effects for time-compressed sentences and phrases. The forms of time compression that were notably difficult for older listeners were uniform time compression and selective time compression of consonants. Indeed, poor performance in recognizing uniformly time-compressed speech was attributed primarily to difficulty in recognizing speech that incorporated selective time compression of consonants. Hearing loss effects were observed also for most of the listening conditions, although these effects were independent of the aging effects. In general, the findings support the notion that the problems of older listeners in recognizing time-compressed speech are associated with difficulty in processing the brief, limited acoustic cues for consonants that are inherent in rapid speech.

“…Relatedly, phonemic boundaries of phonetic contrasts cued by spectral changes occurring in short-duration transitions are shifted toward larger spectral differences for older adults (Dorman, Marton, Hannley, & Lindholm, 1985). Various studies have also demonstrated that listeners with sensorineural hearing loss, a common problem among older adults, must process information over longer speech segments in order to identify consonants (Dubno, Dirks, & Schaefer, 1987; Shum & Collins, 1990). An age-related decline in using the spectral and temporal information carried by short-duration segments may contribute to erroneous phoneme categrization among older listerners (Revoile et al, 1991).…”

The authors assessed age differences on self-reported hearing problems on the performance of auditory tasks in the natural environment. The Your Hearing questionnaire was administered to 265 respondents (aged 20-94 years). Both the degree and variability of self-reported hearing problems were found to increase significantly with age, including those associated with listening to speech under conditions of background noise, the perception of normal and distorted speech, and the perception of short segments of speech and the perception of high-pitched sounds. Experienced hearing problems were greater for Ss who judged their hearing as being of poor quality. Findings suggest that self-report measures can provide valuable insights into the impact of age-related hearing disability on daily life that are not provided by more traditional laboratory-based studies.

The present investigation examined the ability of children with and without a hearing loss to correctly reproduce sequences of acoustic stimuli that varied in number, temporal spacing, and type. Forty-eight children took part in the investigation. They were divided into four groups: two groups of 6- and 7-year-old children, 12 with normal hearing and 12 with a sensorineural hearing loss; and two groups of 9- and 10-year-old children, 12 with normal hearing and 12 with a sensorineural hearing loss. All of the children completed auditory temporal sequencing tasks with verbal (/ba/ and /da/) and nonverbal (a 1-kHz pure tone and a wide band noise) acoustic stimuli. For the 6- and 7-year-old children, the results revealed a significant difference between the children with a hearing loss and their peers with normal hearing for immediate recall of verbal sequences. There were no significant differences in performance between the children with a hearing loss and their peers with normal hearing on the nonverbal sequencing tasks or on the nonverbal and verbal memory span tasks. For the 9- and 10-year-old children, the results did not show any significant differences in performance between the two groups of children for the reproduction of sequences containing more than two verbal or nonverbal elements nor for the auditory memory span task when the sequences consisted of verbal stimuli. For the recall of two verbal stimuli with a variable interstimulus interval (ISI) duration, the results showed that the children with a hearing loss experienced more difficulty than the children with normal hearing. Overall, the results indicated that on the auditory sequential organization tasks, the poorer performance of the children with a hearing loss is likely attributable to auditory perceptual processing deficits rather than to poorer short-term memory capabilities. Also, an analysis of the data revealed that the older children obtained significantly better results than the younger children on auditory sequential organization tasks.
