Modulation Detection Interference

This study was designed to examine age effects on various auditory perceptual skills using a large group of listeners (155 adults, 121 aged 60–88 years and 34 aged 18–30 years), while controlling for the factors of hearing loss and working memory (WM). All subjects completed 3 measures of WM, 7 psychoacoustic tasks (24 conditions) and a hearing assessment. Psychophysical measures were selected to tap phenomena thought to be mediated by higher-level auditory function and included modulation detection, modulation detection interference, informational masking (IM), masking level difference (MLD), anisochrony detection, harmonic mistuning, and stream segregation. Principal-components analysis (PCA) was applied to each psychoacoustic test. For 6 of the 7 tasks, a single component represented performance across the multiple stimulus conditions well, whereas the modulation-detection interference (MDI) task required two components to do so. The effect of age was analyzed using a general linear model applied to each psychoacoustic component. Once hearing loss and WM were accounted for as covariates in the analyses, estimated marginal mean thresholds were lower for older adults on tasks based on temporal processing. When evaluated separately, hearing loss led to poorer performance on roughly 1/2 the tasks and declines in WM accounted for poorer performance on 6 of the 8 psychoacoustic components. These results make clear the need to interpret age-group differences in performance on psychoacoustic tasks in light of cognitive declines commonly associated with aging, and point to hearing loss and cognitive declines as negatively influencing auditory perceptual skills.

Hearing Assessment

Abstract Background The population of older people in residential homes is projected to rise. There are unrecognized hearing difficulties among residents and prevalence of hearing loss in this population is underreported. This can result in an overestimation of levels of cognitive impairment. Untreated hearing loss is associated with social isolation, depression, disruptive behaviour and cognitive decline. This study aimed to explore the provision of hearing care (hearing assessment, rehabilitation and staff training) in Scottish care homes for older people. Methods A survey comprising 18 questions was distributed to the managers (or designated staff members) of 659 care homes across Scotland. Results Responses were obtained from 154 care homes. The results support existing evidence that hearing is not assessed in the majority of homes, resulting in under detection of hearing loss. Staff lack training in supporting residents’ hearing needs. Access to hearing care in residential homes differs across health board areas. Conclusions There is an urgent requirement for hearing assessment of older adults on admission to residential care. Care providers require this information to construct effective care plans and mitigate the effects of hearing loss. Those responsible for providing hearing rehabilitation services require information about service users to address any unmet need.

Auditory Systems

Masking-level differences in quiet at 500 Hz were used to demonstrate evidence of elevated noise levels within the auditory systems of subjects with assumed neural presbycusis. The following five groups of subjects were evaluated: normal-hearing young and old adults; and older adults with metabolic, sensory, or neural presbycusis. The group with assumed neural presbycusis—that is, bilateral high-frequency sensorineural hearing loss and poor word-recognition performance—had masking-level differences (a) in quiet that were significantly larger than those for the other groups and (b) in noise that were significantly smaller than those for the other groups. The data suggest that elevated internal noise levels accompany neural presbycusis.

Modulation Detection Interference

This study compared Modulation Detection Interference (MDI) in listeners with cochlear hearing loss and in listeners with normal hearing. The study was motivated by questions of temporal resolution in the listeners with cochlear hearing loss as well as by their general difficulty in monitoring target sounds in the presence of competing background noise. The first experiment was similar to the MDI paradigm of Yost and Sheft (1989) and showed an equivalence in performance between the two groups of listeners: MDI brought about by an interfering tone comodulated with the target tone at 10 Hz was about 11 dB in both groups. There was also no difference in MDI magnitude when the modulation rate of the interferer changed to 25 Hz, indicating a lack of tuning to differential modulation rate in the gated paradigm employed here. The second experiment was analogous in concept to the measurement of a psychophysical tuning curve; the depth of modulation of the interfering carrier was adjusted to just interfere with the detection of a suprathreshold degree of modulation on the target carrier. The listeners with cochlear hearing loss performed quite similarly to the normal group, and the general lack of a frequency effect for the carrier tones suggested that MDI was relatively insensitive to presumed differences in auditory filter bandwidth between listeners. Because the basis of MDI has been hypothesized to be the fusion of the interfering tone with the target tone, the results of this study suggest that the auditory grouping factors presumed to underlie MDI are intact in listeners with hearing loss of cochlear origin.

Age Related Hearing Loss

Objectives Older adults are at risk for age-related hearing loss and for dementia. Hearing loss increases the risk of dementia and accelerates cognitive decline. There is no cure for dementia, but hearing loss is treatable. Medical professionals who work with individuals with dementia are surveyed to explore whether recommendations made to individuals diagnosed with dementia include hearing assessments. Method A convenience sample of 85 medical professionals in California, Illinois, and Indiana responded to paper surveys in October 2018–April 2019. Results Of the 85 participants, 69 had some level of involvement with dementia. Of these, 16 (23%) reported recommending hearing assessment, and only one (1.45%) reported considering hearing assessment in the top three priorities of recommendations. Conclusions Hearing assessment is not currently a priority for the surveyed medical professionals who work with dementia populations. Advocacy is needed to close the gap between research and practice.

Audiologic Evaluation

For this exploratory cross-disciplinary study, a speech-language pathologist and an audiologist collaborated to investigate the effects of objective and subjective hearing loss on cognition and memory in 11 older adults without hearing loss (OAs), 6 older adults with unaided hearing loss (HLOAs), and 16 young adults (YAs). All participants received cognitive testing and a complete audiologic evaluation including a subjective questionnaire about perceived hearing difficulty. Memory testing involved listening to or reading aloud a text passage then verbally recalling the information. Key findings revealed that objective hearing loss and subjective hearing loss were correlated and both were associated with a cognitive screening test. Potential clinical implications are discussed and include a need for more cross-professional collaboration in assessing older adults with hearing loss.
