Hearing impairment is highly prevalent, but little known about hearing health care among older minority adults.We analyzed nationally representative, cross-sectional data from 1,544 adults ≥ 70 years with audiometry and the 2005-2006 2009-2010 National Health Nutritional Examination Surveys.After adjusting for age speech frequency pure tone average, Blacks (odds ratio [OR] = 1.68, vs. Whites) those greater education (OR 1.63, college < high school) were more likely to report recent testing,...
This study investigated the interaction between hearing loss, reverberation, and age on benefit of spatially separating multiple masking talkers from a target talker. Four listener groups were tested based status age. On every trial listeners heard three different sentences spoken simultaneously by female talkers. Listeners reported keywords sentence, which was presented at fixed known location. Maskers colocated with or separated symmetrically placed loudspeakers, creating situation no...
As international research studies become more commonplace, the importance of developing multilingual instruments continues to increase and with it that translated materials. It is therefore not unexpected assessing quality materials (e.g., instruments, questionnaires, etc.) has essential cross-cultural research, given reliability validity findings crucially depend on instruments. In some fields public health medicine), can also impact effectiveness success interventions campaigns....
Spatial release from masking was studied in a three-talker soundfield listening experiment. The target talker presented at 0 degrees azimuth and the maskers were either colocated or symmetrically positioned around target, with different masker on each side. symmetric placement greatly reduced any "better ear" advantage. When separated by +/-15 , average spatial 8 dB. Wider separations increased to more than 12 This large effect eliminated when binaural cues perceived separation degraded...
This study examined spatial release from masking (SRM) when a target talker was masked by competing talkers or other types of sounds. The focus on the role interaural time differences (ITDs) and time-varying level (ILDs) under conditions varying in strength informational (IM). In first experiment, two that were either colocated with symmetrically spatially separated stimuli presented through loudspeakers. sounds filtered into different frequency regions to restrict available cues. largest...
Age-related hearing loss negatively affects health outcomes, yet disparities in care, such as aid use, exist based on race/ethnicity and socioeconomic position. Recent national efforts highlight reduction of care a public imperative. This study a) describes community engagement approach to addressing disparities, b) reports preliminary outcomes novel intervention, c) discusses implementation processes potential for wide-scale testing use.
This study examines individual differences in producing the sibilant contrast American English and relation of those to 2 speaker characteristics: (a) use a quantal biomechanical effect (called "saturation effect") sibilants (b) performance on test discrimination. Twenty participants produced /s/ /∫/ normal-, clear-, fast-speaking conditions. The degree which used saturation was assessed with custom-made sensor that measured contact underside tongue tip lower alveolar ridge; such normally...
Perceptual skills can be improved even in adulthood, but this learning seldom occurs by stimulus exposure alone. Instead, it requires considerable practice performing a perceptual task with relevant stimuli. It is thought that performance permits the stimuli to drive learning. A corresponding assumption same do not contribute improvement when encountered separately from because of absence permissive signal. However, these ideas are based on only two types studies, which was either always...
This study tested the hypothesis that reduction in spatial release from masking (SRM) resulting sensorineural hearing loss competing speech mixtures is influenced by characteristics of interfering speech. A frontal target was presented simultaneously with two intelligible or time-reversed (unintelligible) maskers were either colocated symmetrically separated horizontal plane. The difference SRM between listeners impairment and normal substantially larger for forward (deficit 5.8 dB) than...
In underserved areas, it is crucial to investigate ways of increasing access hearing health care. The community worker (CHW) a model that has been applied increase in various arenas. This article proposes further investigation into the application this audiology.To assess feasibility training CHWs about loss as possible approach accessibility support services an area.A specialized three-phase process for was developed, implemented, and evaluated by audiologists public researchers. included...
Untreated hearing loss is recognized as a growing global health priority because of its prevalence and harmful effects on well-being. Until recently, little progress had been made in expanding care beyond traditional clinic-based models to incorporate public approaches that increase accessibility affordability care. As demonstrated numerous countries for many conditions, sharing health-care tasks with community workers (CHWs) offers advantages complementary approach expand health-service...
The benefit of wearing hearing aids in multitalker, reverberant listening environments was evaluated a study speech-on-speech masking with two groups listeners loss (younger/older). Listeners selectively attended known spatial location room conditions (low/high reverberation) and identified target speech the presence competing talkers that were either colocated or symmetrically spatially separated from target. amount release (SRM) bilateral similar to when unaided at near an equivalent...

Method Readability levels were calculated using Fry Graph adapted for Spanish, as well Fernandez-Huerta Spaulding formulae commonly used PROMs....
Importance Age-related hearing loss that impairs daily communication is associated with adverse health outcomes, but use of aids by older adults low and disparities exist. Objective To test whether an affordable, accessible care intervention, delivered community workers using over-the-counter technology, could improve self-perceived function among compared a wait-list control. Design, Setting, Participants Open-label randomized clinical trial conducted between April 2018 October 2019 3-month...
Hearing loss is associated with cognitive decline and impairment in daily living activities. Access to hearing health care has broad implications for healthy aging of the U.S. population. This qualitative study investigated factors related socio-ecological domains a US-Mexico border community experiencing disparities access care. A multidisciplinary research team partnered Community Health Workers (CHWs) from Federally Qualified Center designing study. CHWs conducted interviews people (n=20)...
Purpose Teleaudiology helps connect patients in rural and underresourced areas to hearing health care providers, minimizing the barrier of geography (Swanepoel et al., 2010). In United States, teleaudiology is at initial stages implementation (Bush, Thompson, Irungu, & Ayugi, 2016). Telehealth researchers recommend conducting a comprehensive planning assessment optimize adoption (AlDossary, Martin-Khan, Bradford, Armfield, Smith, 2017; Alverson 2008; Krupinski, 2015). A geographic...
Language acquisition typically involves periods when the learner speaks and listens to new language, others is exposed language without consciously speaking or listening it. Adaptation variants of a native occurs under similar conditions. Here, speech learning by adults was assessed following training regimen that mimicked this common situation immersion continuous active processing. Experiment 1 focused on novel phonetic category along voice-onset-time continuum, while 2 adaptation...
The purpose of this study was to investigate the feasibility Community Health Workers (CHWs) as patient-site facilitators in teleaudiology-facilitated hearing aid services improve rehabilitation outcomes for older Hispanic/Latino adults a medically underserved, rural, US-Mexico border community.
