ABSTRACT
BACKGROUND: Hearing loss is associated with increased cognitive decline and incident dementia in older adults. We aimed to investigate whether a hearing intervention could reduce cognitive decline in cognitively healthy older adults with hearing loss. METHODS: The ACHIEVE study is a multicentre, parallel-group, unmasked, randomised controlled trial of adults aged 70-84 years with untreated hearing loss and without substantial cognitive impairment that took place at four community study sites across the USA. Participants were recruited from two study populations at each site: (1) older adults participating in a long-standing observational study of cardiovascular health (Atherosclerosis Risk in Communities [ARIC] study), and (2) healthy de novo community volunteers. Participants were randomly assigned (1:1) to a hearing intervention (audiological counselling and provision of hearing aids) or a control intervention of health education (individual sessions with a health educator covering topics on chronic disease prevention) and followed up every 6 months. The primary endpoint was 3-year change in a global cognition standardised factor score from a comprehensive neurocognitive battery. Analysis was by intention to treat. This trial was registered at ClinicalTrials.gov, NCT03243422. FINDINGS: From Nov 9, 2017, to Oct 25, 2019, we screened 3004 participants for eligibility and randomly assigned 977 (32·5%; 238 [24%] from ARIC and 739 [76%] de novo). We randomly assigned 490 (50%) to the hearing intervention and 487 (50%) to the health education control. The cohort had a mean age of 76·8 years (SD 4·0), 523 (54%) were female, 454 (46%) were male, and most were White (n=858 [88%]). Participants from ARIC were older, had more risk factors for cognitive decline, and had lower baseline cognitive scores than those in the de novo cohort. In the primary analysis combining the ARIC and de novo cohorts, 3-year cognitive change (in SD units) was not significantly different between the hearing intervention and health education control groups (-0·200 [95% CI -0·256 to -0·144] in the hearing intervention group and -0·202 [-0·258 to -0·145] in the control group; difference 0·002 [-0·077 to 0·081]; p=0·96). However, a prespecified sensitivity analysis showed a significant difference in the effect of the hearing intervention on 3-year cognitive change between the ARIC and de novo cohorts (pinteraction=0·010). Other prespecified sensitivity analyses that varied analytical parameters used in the total cohort did not change the observed results. No significant adverse events attributed to the study were reported with either the hearing intervention or health education control. INTERPRETATION: The hearing intervention did not reduce 3-year cognitive decline in the primary analysis of the total cohort. However, a prespecified sensitivity analysis showed that the effect differed between the two study populations that comprised the cohort. These findings suggest that a hearing intervention might reduce cognitive change over 3 years in populations of older adults at increased risk for cognitive decline but not in populations at decreased risk for cognitive decline.

INTRODUCTION: Age-related sensory and motor impairment are associated with risk of dementia. No study has examined the joint associations of multiple sensory and motor measures on prevalence of early cognitive impairment (ECI). METHODS: Six hundred fifty participants in the Baltimore Longitudinal Study of Aging completed sensory and motor function tests. The association between sensory and motor function and ECI was examined using structural equation modeling with three latent factors corresponding to multisensory, fine motor, and gross motor function. RESULTS: The multisensory, fine, and gross motor factors were all correlated (r = 0.74 to 0.81). The odds of ECI were lower for each additional unit improvement in the multisensory (32%), fine motor (30%), and gross motor factors (12%). DISCUSSION: The relationship between sensory and motor impairment and emerging cognitive impairment may guide future intervention studies aimed at preventing and/or treating ECI. HIGHLIGHTS: Sensorimotor function and early cognitive impairment (ECI) prevalence were assessed via structural equation modeling. The degree of fine and gross motor function is associated with indicators of ECI. The degree of multisensory impairment is also associated with indicators of ECI.

INTRODUCTION: Many neurocognitive evaluations involve auditory stimuli, yet there are no standard testing guidelines for individuals with hearing loss. The ensuring speech understanding (ESU) test was developed to confirm speech understanding and determine whether hearing accommodations are necessary for neurocognitive testing. METHODS: Hearing was assessed using audiometry. The probability of ESU test failure by hearing status was estimated in 2679 participants (mean age: 81.4 ± 4.6 years) using multivariate logistic regression. RESULTS: Only 2.2% (N = 58) of participants failed the ESU test. The probability of failure increased with hearing loss severity; similar results were observed for those with and without mild cognitive impairment or dementia. DISCUSSION: The ESU test is appropriate for individuals who have variable degrees of hearing loss and cognitive function. This test can be used prior to neurocognitive testing to help reduce the risk of hearing loss and compromised auditory access to speech stimuli causing poorer performance on neurocognitive evaluation.

We aimed to assess the associations of peripheral neuropathy (PN) with vision and hearing impairment among adults aged ≥40 years who attended the lower-extremity disease exam for the National Health and Nutrition Examination Survey (United States, 1999-2004). Overall, 11.8% (standard error (SE), 0.5) of adults had diabetes, 13.2% (SE, 0.5) had PN (26.6% (SE, 1.4) with diabetes, 11.4% (SE, 0.5) without diabetes), 1.6% (SE, 0.1) had vision impairment, and 15.4% (SE, 1.1) had hearing impairment. The prevalence of vision impairment was 3.89% (95% CI: 2.99, 5.05) among adults with PN and 1.29% (95% CI: 1.04, 1.60) among adults without PN (P < 0.001). After adjustment, PN was associated with vision impairment overall (odds ratio (OR) = 1.48, 95% confidence interval (CI): 1.03, 2.13) and among adults without diabetes (OR = 1.80, 95% CI: 1.17, 2.77) but not among adults with diabetes (P for interaction = 0.018). The prevalence of hearing impairment was 26.5% (95% CI: 20.4, 33.7) among adults with PN and 14.2% (95% CI: 12.4, 16.3) among adults without PN (P < 0.001). The association of PN with moderate/severe hearing impairment was significant overall (OR = 2.55, 95% CI: 1.40, 4.64) and among adults without diabetes (OR = 3.26, 95% CI: 1.80, 5.91). Overall, these findings suggest an association between peripheral and audiovisual sensory impairment that is unrelated to diabetes.

AIMS: Hearing impairment (HI) is prevalent among middle-aged and older adults, but few studies have examined its mental health consequences in China. This study investigated the association of HI with depressive symptoms and whether family financial support moderated the association among adults aged 45 in China. METHODS: Data were obtained from three waves of the China Health and Retirement Longitudinal Study (2011, 2013 and 2015). Hearing impairment was defined as a self-reported hearing problem in one or both ears. Depressive symptoms were measured with CESD-10. Associations between HI and depressive symptoms were modeled using fixed-effect models. RESULTS: People with self-reported hearing loss were more likely than those without hearing loss to have depressive symptoms, with an odds ratio of 1.25 [1.07-1.47]. The association remained significant after adjusting for socio-demographic characteristics, lifestyle behaviors, and health conditions. Family financial support moderated this association. Among those with HI, adults with a higher level of family financial support tend to have better performance on symptoms of depression. CONCLUSIONS: HI was positively associated with depressive symptoms among adults aged ≥45 in China, and family financial support played a buffering role in the relationship between HI and depressive symptoms.

OBJECTIVE: Studies investigating hearing interventions under-utilise and under-report treatment fidelity planning, implementation, and assessment. This represents a critical gap in the field that has the potential to impede advancements in the successful dissemination and implementation of interventions. Thus, our objective was to describe treatment fidelity planning and implementation for hearing intervention in the multi-site Ageing and Cognitive Health Evaluation in Elders (ACHIEVE) randomised controlled trial. DESIGN: Our treatment fidelity plan was based on a framework defined by the National Institutes of Health Behaviour Change Consortium (NIH BCC), and included strategies to enhance study design, provider training, and treatment delivery, receipt, and enactment. STUDY SAMPLE: To assess the fidelity of the ACHIEVE hearing intervention, we distributed a checklist containing criteria from each NIH BCC core treatment fidelity category to nine raters. RESULTS: The ACHIEVE hearing intervention fidelity plan satisfied 96% of NIH BCC criteria. Our assessment suggested a need for including clear, objective definitions of provider characteristics and non-treatment aspects of intervention delivery in future fidelity plans. CONCLUSIONS: The ACHIEVE hearing intervention fidelity plan can serve as a framework for the application of NIH BCC fidelity strategies for future studies and enhance the ability of researchers to reliably implement evidence-based interventions.

Importance: Age-related hearing loss that impairs daily communication is associated with adverse health outcomes, but use of hearing aids by older adults is low and disparities exist. Objective: To test whether an affordable, accessible hearing care intervention, delivered by community health workers using over-the-counter hearing technology, could improve self-perceived communication function among older adults with hearing loss compared with a wait-list control. Design, Setting, and Participants: Open-label randomized clinical trial conducted between April 2018 and October 2019 with 3-month data collection completed in June 2020. The trial took place at 13 community sites, including affordable independent housing complexes (n = 10), senior centers (n = 2), and an older adult social club (n = 1) in Baltimore, Maryland. A total of 151 participants aged 60 years or older with hearing loss were randomized. Interventions: Participants were randomized to receive a community health worker-delivered hearing care intervention (n = 78) or to a wait-list control group (n = 73). The 2-hour intervention consisted of fitting a low-cost amplification device and instruction. Main Outcomes and Measures: The primary outcome was change in self-perceived communication function (Hearing Handicap Inventory for the Elderly-Screening Version [HHIE-S]; score range, 0-40; higher scores indicate poorer function) from baseline to 3 months postrandomization. The average treatment effect was estimated using the doubly robust weighted least squares estimator, which uses an outcome regression model weighted by the inverse probability of attrition to account for baseline covariate imbalance and missing data. Results: Among 151 participants randomized (mean age, 76.7 [SD, 8.0] years; 101 [67.8%] women; 65 [43%] self-identified as African American; 96 [63.6%] with low income [<$25â¯000 annual household income]), 136 (90.1%) completed 3-month follow-up for the primary outcome. In the intervention group, 90.5% completed the intervention session and reported at least 1 hour of daily amplification use at 3 months postrandomization. Mean scores for the HHIE-S were 21.7 (SD, 9.4) at baseline and 7.9 (SD, 9.2) at 3 months (change of -13.2 [SD, 10.3]) in the intervention group, and 20.1 (SD, 10.1) at baseline and 21 (SD, 9.1) at 3 months (change of 0.6 [SD, 7.1]) in the control group. Self-perceived communication function significantly improved in the intervention group compared with the control group, with an estimated average treatment effect of the intervention of a -12.98-point HHIE-S change (95% CI, -15.51 to -10.42). No study-related adverse events were reported. Conclusions and Relevance: Among older adults with hearing loss, a community health worker-delivered personal sound amplification device intervention, compared with a wait-list control, significantly improved self-perceived communication function at 3 months. Findings are limited by the absence of a sham control, and further research is needed to understand effectiveness compared with other types of care delivery models and amplification devices.

BACKGROUND/OBJECTIVES: Nearly 38 million Americans have hearing loss. Understanding how sensory deficits such as hearing loss, which limit communication, impact satisfaction has implications for Medicare value-based reimbursement mechanisms. The aim of this study was to characterize the association of functional hearing loss and dissatisfaction with quality of health care over the past year among Medicare beneficiaries. METHODS: Cross-sectional study of satisfaction with quality of health care among Medicare beneficiaries with self-reported trouble hearing from the 2015 Medicare Current Beneficiaries Survey. There were 11,441 Medicare beneficiaries representing a 48.6 million total weighted nationally representative sample. RESULTS: Forty-eight percent of Medicare beneficiaries reported a little or a lot of trouble hearing. Medicare beneficiaries with a little trouble hearing (odds ratio=1.496; 95% confidence interval, 1.079-2.073; P=0.016) and a lot of trouble hearing (odds ratio=1.769; 95% confidence interval, 1.175-2.664; P=0.007) had 49.6% and 76.9% higher odds of being dissatisfied with the quality of their health care over the previous year, respectively. CONCLUSIONS: Medicare beneficiaries with functional hearing loss had higher odds of dissatisfaction with health care over the past year compared to those without functional hearing loss. Given Medicare's reliance on patient satisfaction as a value-based measure for hospital reimbursement, interventions to address hearing loss in the health care system are needed.

Neuropsychiatric symptoms (NPS) in persons with dementia (PWD) are common and can lead to poor outcomes, such as institutionalization and mortality, and may be exacerbated by sensory loss. Hearing loss is also highly prevalent among older adults, including PWD. OBJECTIVE: This study investigated the association between hearing loss and NPS among community- dwelling patients from a tertiary memory care center. DESIGN, SETTING, AND PARTICIPANTS: Participants of this cross-sectional study were patients followed at the Johns Hopkins Memory and Alzheimer's Treatment Center who underwent audiometric testing during routine clinical practice between October 2014 and January 2017. OUTCOME MEASUREMENTS: Included measures were scores on the Neuropsychiatric Inventory-Questionnaire and the Cornell Scale for Depression in Dementia. RESULTS: Participants (nâ¯=â¯101) were on average 76 years old, mostly female and white, and had a mean Mini-Mental State Examination score of 23. We observed a positive association between audiometric hearing loss and the number of NPS (bâ¯=â¯0.7 per 10 dB; 95% confidence interval [CI]: 0.2, 1.1; tâ¯=â¯2.86; pâ¯=â¯0.01; dfâ¯=â¯85), NPS severity (bâ¯=â¯1.3 per 10 dB; 95% CI: 0.4, 2.5; tâ¯=â¯2.13; pâ¯=â¯0.04; dfâ¯=â¯80), and depressive symptom severity (bâ¯=â¯1.5 per 10 dB; 95% CI: 0.4, 2.5; tâ¯=â¯2.83; pâ¯=â¯0.01; dfâ¯=â¯89) after adjustment for demographic and clinical characteristics. Additionally, the use of hearing aids was inversely associated with the number of NPS (bâ¯=â¯-2.09; 95% CI -3.44, -0.75; tâ¯=â¯-3.10; pâ¯=â¯0.003; dfâ¯=â¯85), NPS severity (bâ¯=â¯-3.82; 95% CI -7.19, -0.45; tâ¯=â¯-2.26; pâ¯=â¯0.03; dfâ¯=â¯80), and depressive symptom severity (bâ¯=â¯-2.94; 95% CI: -5.93, 0.06; tâ¯=â¯1.70; pâ¯=â¯0.05; dfâ¯=â¯89). CONCLUSION: Among patients at a memory clinic, increasing severity of hearing loss was associated with a greater number of NPS, more severe NPS, and more severe depressive symptoms, while hearing aid use was associated with fewer NPS, lower severity, and less severe depressive symptoms. Identifying and addressing hearing loss may be a promising, low-risk, non-pharmacological intervention in preventing and treating NPS.

INTRODUCTION: Hearing impairment is associated with poor cognitive test performance in older adults. However, hearing's impact on cognitive test completion is poorly described, and missing cognitive data due to hearing impairment could misestimate the association. METHODS: We investigated if hearing impairment is associated with missing neurocognitive scores in 3678 adults (72-94 years). Hearing impairment was defined by the better-ear pure tone average of speech-frequency thresholds (0.5-4 kHz) >25 decibels. RESULTS: Hearing impairment was associated with greater missingness on all auditory-only tests, including Logical Memory (prevalence ratio [PR] comparing ≥ moderate impairment vs normal hearing:1.68, 95% confidence interval [CI] 1.26, 2.25) and Digits Backwards (PR 1.62; 95% CI 1.21, 2.17); and two non-auditory tests, Boston Naming (PR 1.61; 95% CI 1.21, 2.17) and Trail Making B (PR 1.55; 95% CI 1.29, 1.86). Models that imputed missing cognitive scores showed the strongest hearing-cognition associations. DISCUSSION: Older adults with hearing impairment are less likely to complete cognitive testing, thereby underestimating the hearing impairment-cognition relationship.

OBJECTIVES: This work describes the development of a manualized best-practice hearing intervention for older adults participating in the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) randomized controlled clinical trial. Manualization of interventions for clinical trials is critical for assuring intervention fidelity and quality, especially in large multisite studies. The multisite ACHIEVE randomized controlled trial is designed to assess the efficacy of a hearing intervention on rates of cognitive decline in older adults. We describe the development of the manualized hearing intervention through an iterative process that included addressing implementation questions through the completion of a feasibility study (ACHIEVE-Feasibility). DESIGN: Following published recommendations for manualized intervention development, an iterative process was used to define the ACHIEVE-hearing intervention elements and create an initial manual. The intervention was then delivered within the ACHIEVE-Feasibility study using one-group pre-post design appropriate for assessing questions related to implementation. Participants were recruited from the Tampa, Florida area between May 2015 and April 2016. Inclusion criteria were cognitively healthy adults aged 70 to 89 with symmetrical mild-to-moderately severe sensorineural hearing loss. The ACHIEVE-Feasibility study sought to assess the implementation of the manualized hearing intervention by: (1) confirming improvement in expected outcomes were achieved including aided speech-in-noise performance and perception of disease-specific self-report measures; (2) determining whether the participants would comply with the intervention including session attendance and use of hearing aids; and (3) determining whether the intervention sessions could be delivered within a reasonable timeframe. RESULTS: The initial manualized intervention that incorporated the identified best-practice elements was evaluated for feasibility among 21 eligible participants and 9 communication partners. Post-intervention expected outcomes were obtained with speech-in-noise performance results demonstrating a significant improvement under the aided condition and self-reported measures showing a significant reduction in self-perceived hearing handicap. Compliance was excellent, with 20 of the 21 participants (95.2%) completing all intervention sessions and 19 (90.4%) returning for the 6-month post-intervention visit. Furthermore, self-reported hearing aid compliance was >8 hr/day, and the average daily hearing aid use from datalogging was 7.8 hr. Study completion was delivered in a reasonable timeframe with visits ranging from 27 to 85 min per visit. Through an iterative process, the intervention elements were refined, and the accompanying manual was revised based on the ACHIEVE-Feasibility study activities, results, and clinician and participant informal feedback. CONCLUSION: The processes for the development of a manualized intervention described here provide guidance for future researchers who aim to examine the efficacy of approaches for the treatment of hearing loss in a clinical trial. The manualized ACHIEVE-Hearing Intervention provides a patient-centered, yet standardized, step-by-step process for comprehensive audiological assessment, goal setting, and treatment through the use of hearing aids, other hearing assistive technologies, counseling, and education aimed at supporting self-management of hearing loss. The ACHIEVE-Hearing Intervention is feasible in terms of implementation with respect to verified expected outcomes, compliance, and reasonable timeframe delivery. Our processes assure intervention fidelity and quality for use in the ACHIEVE randomized controlled trial (ClinicalTrials.gov Identifier: NCT03243422).

BACKGROUND: Hearing loss, a highly prevalent sensory impairment affecting older adults, is a risk factor for cognition decline. However, there were very limited studies on this association in low-resource countries. This study aimed to assess the association between self-reported hearing loss and cognitive decline, and whether engagement in leisure activities moderated this association among older adults in China. METHODS: Data were obtained from two waves of the nationally representative survey of China Longitudinal Healthy Longevity Survey (CLHLS) between 2011/12-2014. Eight thousand eight hundred forty-four individuals aged 65 years old or above with a dichotomized measure of self-reported hearing status were included. Modified Mini-Mental Examination (MMSE) was used to measure global cognition. Fixed-effects models were used to estimate whether leisure activity engagement moderated the association of self-perceived hearing loss with global cognitive change in the overall sample and sex subsamples. RESULTS: Self-reported hearing loss was associated with cognitive impairment, with an odds ratio of 2.48 [1.22, 5.06]. Sex difference in the association of hearing loss and cognitive impairment was not found. Self-reported hearing loss was associated with cognitive decline, with 8% increase in risk compared with those with normal hearing. Frequent engagement in leisure activities moderated the association between hearing loss and cognitive decline for the whole and male samples. CONCLUSION: Hearing loss was associated with cognitive decline, and leisure activities engagement moderated the association among males rather than females.

INTRODUCTION: As hearing loss has been identified as an important risk factor for dementia, we aimed to assess the association between hearing loss and microstructural integrity of the brain. METHODS: A total of 1086 dementia-free participants (mean age = 75.2 [standard deviation: 4.9], 61.4% female) of the population-based Atherosclerosis Risk in Communities (ARIC) study underwent hearing assessment (2016-2017) and magnetic resonance imaging of the brain (2011-2013). Microstructural integrity was determined with diffusion tensor imaging. Multivariable linear regression was used to investigate associations between hearing loss and microstructural integrity of different brain regions and white matter (WM) tracts. RESULTS: Hearing loss was associated with lower WM microstructural integrity in the temporal lobe, lower gray matter integrity of the hippocampus, and with lower WM microstructural integrity of the limbic tracts and the uncinate fasciculus. CONCLUSION: Our results demonstrate that hearing loss is indepedently associated with lower microstructural integrity in brain regions that are important for different cognitive processes.

As the proportion of older adults in the world's total population continues to grow, the adverse health outcomes of age-related hearing loss are becoming increasingly recognized. While research has shown that age-related hearing loss is the single greatest modifiable risk factor for dementia, use of hearing aids remains low worldwide, even in many middle- and high-income countries. Reasons for poor uptake of hearing aids are likely to involve a combination of factors, ranging from increasing costs of hearing aid technology to a widespread lack of insurance coverage. This article aims to identify the current state of access to hearing aids, focusing on eight middle- and high-income countries. We discuss how to facilitate greater access to hearing aids for patients by addressing changes in how devices are regulated, technological advancements in hearing devices, the need to adjust reimbursement schemes and the importance of adaptation among the community workforce for hearing-care.
Alors que la proportion de personnes âgées au sein de la population mondiale totale continue à croître, les effets néfastes sur la santé de la perte de l'acuité auditive liée à l'âge sont de plus en plus reconnus. Bien que la recherche ait démontré que la perte de l'acuité auditive liée à l'âge est le principal facteur de risque modifiable de la démence, l'utilisation de prothèses auditives reste limitée à l'échelle mondiale, y compris dans de nombreux pays à revenu intermédiaire et élevé. Les raisons de ce recours limité aux prothèses auditives tiennent probablement à une combinaison de facteurs qui vont des coûts croissants de la technologie des appareils auditifs à un manque généralisé de couverture médicale. Cet article vise à déterminer l'état actuel de l'accès aux prothèses auditives en se concentrant sur huit pays à revenu intermédiaire et élevé. Nous étudions comment permettre aux patients d'accéder plus facilement aux prothèses auditives en tenant compte de la réglementation applicable aux appareils, des progrès technologiques relatifs aux appareils auditifs, de la nécessité d'ajuster les systèmes de remboursement et de l'importance de l'adaptation au sein de la main-d'Åuvre locale pour les soins auditifs.
A medida que la proporción de adultos mayores en la población total del mundo continúa creciendo, los resultados adversos para la salud de la pérdida de audición relacionada con la edad son cada vez más reconocidos. Aunque las investigaciones han demostrado que la pérdida de audición relacionada con la edad es el mayor factor de riesgo modificable para la demencia, el uso de audífonos sigue siendo bajo en todo el mundo, incluso en muchos países de ingresos medios y altos. Las causas de la escasa aceptación de los audífonos pueden ser una combinación de factores, que van desde el aumento de los costes de la tecnología de los audífonos hasta la falta generalizada de cobertura de seguro. Este artículo pretende identificar el estado actual del acceso a los audífonos, centrándose en ocho países de ingresos medios y altos. Discutimos cómo facilitar un mayor acceso a los audífonos para los pacientes abordando los cambios en cómo se regulan los dispositivos, los avances tecnológicos en los audífonos, la necesidad de ajustar los esquemas de reembolso y la importancia de la adaptación entre los trabajadores de la comunidad para el cuidado de la audición.

Objective: While hearing loss is associated with loneliness, the long term impact of hearing loss interventions remains unknown. We investigated levels of loneliness in adults at baseline, 6-months, 1-year and 5-years after receiving a hearing aid (HA) or cochlear implant (CI). Design: In this 5-year follow-up to the Studying Multiple Outcomes after Aural Rehabilitative Treatment study, participants completed the University of California, Los Angeles (UCLA) Loneliness Scale at baseline, 6-months, 1-year, and 5-year time points. Generalized estimating equations modeled the population average UCLA score over time. Study Sample: Analytic cohort of 115 participants (74% of original 156) 50 years or older who received a HA or CI at baseline and completed at least one follow up visit. Results: Loneliness scores were not different at 5 years versus baseline for HA users. CI users showed significantly reduced loneliness at 6-months and 1-year from baseline and with no significant difference at 5 years. Conclusion: Over 5 years, we observed no increase in loneliness from baseline in a cohort of adults receiving HAs and CIs. Short-term reduction in loneliness in CI users was demonstrated. Future randomized trials are needed to definitively assess the impact of treated versus untreated hearing loss on loneliness.

Ensuring that older adults in long-term care settings can effectively communicate is important. The goal of this study was to characterize key modifiable factors that could affect verbal communication in an adult day care setting, namely prevalence of audiometric hearing loss and the acoustic characteristics in the activity hall. The prevalence of age-related hearing loss among participants (n=51) was 71%, although only 15% of enrollees at the group care setting (n=21 of 140) used amplification. The noise and reverberation characteristics of the activity hall revealed signal-to-noise ratios of -3.1 decibels (dB) and -2.4 dB during morning activity and lunch, respectively, which are poorer than the recommended levels for understanding speech in background noise. Older adults attending adult day services are likely to spend the day in a room with acoustics that are too challenging to understand speech clearly. Opportunities to improve listening environments in group care settings for older adults are discussed.
