Purpose To establish the range of talker variability for vowel intelligibility in clear versus conversational speech for older adults with hearing loss and to determine whether talkers who produced a clear speech benefit for young listeners with normal hearing also did so for older adults with hearing loss. Method Clear and conversational vowels in /bVd/ context produced by 41 talkers were presented in noise for identification by 40 older (ages 65–87 years) adults with sloping sensorineural hearing loss. Results Vowel intelligibility within each speaking style and the size of the clear speech benefit varied widely among talkers. The clear speech benefit was equivalent to that enjoyed by young listeners with normal hearing in an earlier study. Most talkers who had produced a clear speech benefit for young listeners with normal hearing also did so for the older listeners with hearing loss in the present study. However, effects of talker gender differed between listeners with normal hearing and listeners with hearing loss. Conclusion The clear speech vowel intelligibility benefit generated for listeners with hearing loss varied considerably among talkers. Most talkers who produced a clear speech benefit for normal-hearing listeners also produced a benefit for listeners with hearing loss.

AbstractThe interaction of audition and cognition has been of interest to researchers and clinicians, especially as the prevalence of hearing loss and cognitive decline increases with advancing age. Cognitive screening tests are commonly used to assess cognitive status in individuals reporting changes in memory or function or to monitor cognitive status over time. These assessments are administered verbally, so performance may be adversely affected by hearing loss. Previous research on the impact of reduced audibility on cognitive screening test scores has been limited to older adults with sensorineural hearing loss (SNHL) or young adults with normal hearing and simulated audibility loss. No comparisons have been conducted to determine whether age-related SNHL and its impact on cognitive screening tests is successfully modeled by audibility reduction.The purpose of this study was to examine the effects of reduced audibility on the Mini-Mental State Examination (MMSE), a common bedside cognitive screening instrument, by comparing performance of cognitively normal older adults with SNHL and young adults with normal hearing.A 1:1 gender-matched case–control design was used for this study.Thirty older adults (60–80 years old) with mild to moderately severe SNHL (cases) and 30 young adults (18–35 years old) with normal hearing (controls) served as participants for this study. Participants in both groups were selected for inclusion if their cognitive status was within normal limits on the Montreal Cognitive Assessment.Case participants were administered a recorded version of the MMSE in background noise at a signal-to-noise ratio of +25-dB SNR. Control participants were administered a digitally filtered version of the MMSE that reflected the loss of audibility (i.e., threshold elevation) of the matched case participant at a signal-to-noise ratio of +25-dB SNR. Performance on the MMSE was scored using standard criteria.Between-group analyses revealed no significant difference in the MMSE score. However, within-group analyses showed that education was a significant effect modifier for the case participants.Reduced audibility has a negative effect on MMSE score in cognitively intact participants, which contributes to and confirms the findings of earlier studies. The findings suggest that observed reductions in score on the MMSE were primarily due to loss of audibility of the test item. The negative effects of audibility loss may be greater in individuals who have lower levels of educational attainment. Higher levels of educational attainment may offset decreased performance on the MMSE because of reduced audibility. Failure to consider audibility and optimize communication when administering these assessments can lead to invalid results (e.g., false positives or missed information), misdiagnosis, and inappropriate recommendations for medication or intervention.

Perceived Emotion

Purpose In this study, we investigated the emotion perceived by young listeners with normal hearing (YNH listeners) and older adults with hearing impairment (OHI listeners) when listening to speech produced conversationally or in a clear speaking style. Method The first experiment included 18 YNH listeners, and the second included 10 additional YNH listeners along with 20 OHI listeners. Participants heard sentences spoken conversationally and clearly. Participants selected the emotion they heard in the talker's voice using a 6-alternative, forced-choice paradigm. Results Clear speech was judged as sounding angry and disgusted more often and happy, fearful, sad, and neutral less often than conversational speech. Talkers whose clear speech was judged to be particularly clear were also judged as sounding angry more often and fearful less often than other talkers. OHI listeners reported hearing anger less often than YNH listeners; however, they still judged clear speech as angry more often than conversational speech. Conclusions Speech spoken clearly may sound angry more often than speech spoken conversationally. Although perceived emotion varied between YNH and OHI listeners, judgments of anger were higher for clear speech than conversational speech for both listener groups.

Abstract Background Older adults with hearing loss often report difficulty understanding British-accented speech, such as in television or movies, after having understood such speech in the past. A few studies have examined the intelligibility of various United States regional and non-U.S. varieties of English for American listeners, but only for young adults with normal hearing. Purpose This preliminary study sought to determine whether British-accented sentences were less intelligible than American-accented sentences for American younger and older adults with normal hearing and for older adults with hearing loss. Research Design A mixed-effects design, with talker accent and listening condition as within-subjects factors and listener group as a between-subjects factor. Study Sample Three listener groups consisting of 16 young adults with normal hearing, 15 older adults with essentially normal hearing, and 22 older adults with sloping sensorineural hearing loss. Data Collection and Analysis Sentences produced by one General American English speaker and one British English speaker were presented to listeners at 70 dB sound pressure level in quiet and in babble. Signal-to-noise ratios for the latter varied among the listener groups. Responses were typed into a textbox and saved on each trial. Effects of accent, listening condition, and listener group were assessed using linear mixed-effects models. Results American- and British-accented sentences were equally intelligible in quiet, but intelligibility in noise was lower for British-accented sentences than American-accented sentences. These intelligibility differences were similar for all three groups. Conclusion British-accented sentences were less intelligible than those produced by an American talker, but only in noise.

Purpose Seeing the talker's face improves speech understanding in noise, possibly releasing resources for cognitive processing. We investigated whether it improves free recall of spoken two-digit numbers. Method Twenty younger adults with normal hearing and 24 older adults with hearing loss listened to and subsequently recalled lists of 13 two-digit numbers, with alternating male and female talkers. Lists were presented in quiet as well as in stationary and speech-like noise at a signal-to-noise ratio giving approximately 90% intelligibility. Amplification compensated for loss of audibility. Results Seeing the talker's face improved free recall performance for the younger but not the older group. Poorer performance in background noise was contingent on individual differences in working memory capacity. The effect of seeing the talker's face did not differ in quiet and noise. Conclusions We have argued that the absence of an effect of seeing the talker's face for older adults with hearing loss may be due to modulation of audiovisual integration mechanisms caused by an interaction between task demands and participant characteristics. In particular, we suggest that executive task demands and interindividual executive skills may play a key role in determining the benefit of seeing the talker's face during a speech-based cognitive task.

The present investigation examined the effect of reverberation and noise on the perception of nonsense syllables by four groups of subjects: younger (≤35 years of age) and older (>60 years of age) listeners with mild-to-moderate sensorineural hearing loss; younger, normal-hearing individuals; and older adults with minimal peripheral hearing loss. Copies of the Nonsense Syllable Test (Resnick, Dubno, Huffnung, & Levitt, 1975) were re-recorded under four levels of reverberation (0.0, 0.6, 0.9, 1.3 s) in quiet and in cafeteria noise at + 10 dB S:N. Results suggest that both age and amount of pure-tone hearing loss contribute to senescent changes in the ability to understand noisy, reverberant speech: pure-tone threshold and age were correlated negatively with performance in reverberation plus noise, although age and pure-tone hearing loss were not correlated with each other. Further, many older adults with minimal amounts of peripheral hearing loss demonstrated difficulty understanding distorted consonants.

The purpose of this study was to assess the consonant and vowel identification abilities of 12 children with minimal high-frequency hearing loss, 12 children with normal hearing, and 12 young adults with normal hearing using nonsense syllables recorded in a classroom with reverberation time of 0.7 s in two conditions of: (1) quiet and (2) noise (+13 dB S/N against a multi-talker babble). The young adults achieved significantly higher mean consonant and vowel identification scores than both groups of children. The children with normal hearing had significantly higher mean consonant identification scores in quiet than the children with minimal high-frequency hearing loss, but the groups performances did not differ in noise. Further, the two groups of children did not differ in vowel identification performance. Listeners’ responses to consonant stimuli were converted to confusion matrices and submitted to a sequential information analysis (SINFA, Wang & Bilger, 1973). The SINFA determined that the amount of information transmitted, both overall and for individual features, differed as a function of listener group ad listening condition.

The Test of Basic Auditory Capabilities (TBAC) is a battery of auditory-discrimination tasks and speech-identification tasks that has been normed on several hundred young normal-hearing adults. Previous research with the TBAC suggested that cognitive function may impact the performance of older adults. Here, we examined differences in performance on several TBAC tasks between a group of 34 young adults with a mean age of 22.5 years (SD = 3.1 years) and a group of 115 older adults with a mean age of 69.2 years (SD = 6.2 years) recruited from the local community. Performance of the young adults was consistent with prior norms for this age group. Not surprisingly, the two groups differed significantly in hearing loss and working memory with the older adults having more hearing loss and poorer working memory than the young adults. The two age groups also differed significantly in performance on six of the nine measures extracted from the TBAC (eight test scores and one average test score) with the older adults consistently performing worse than the young adults. However, when these age-group comparisons were repeated with working memory and hearing loss as covariates, the groups differed in performance on only one of the nine auditory measures from the TBAC. For eight of the nine TBAC measures, working memory was a significant covariate and hearing loss never emerged as a significant factor. Thus, the age-group deficits observed initially on the TBAC most often appeared to be mediated by age-related differences in working memory rather than deficits in auditory processing. The results of these analyses of age-group differences were supported further by linear-regression analyses with each of the 9 TBAC scores serving as the dependent measure and age, hearing loss, and working memory as the predictors. Regression analyses were conducted for the full set of 149 adults and for just the 115 older adults. Working memory again emerged as the predominant factor impacting TBAC performance. It is concluded that working memory should be considered when comparing the performance of young and older adults on auditory tasks, including the TBAC.
