Purpose: This study explores the underutilized pedagogical approach of incorporating lived experiences of parents with children possessing diverse hearing profiles and their family characteristics into the audiology curriculum for students. The aim was to investigate the impact of integrating such experiences into the classroom as an andragogical learning experience through the qualitative analysis of written student reflections.

Method: Twelve (N = 12) third-year female audiology students enrolled in a pediatric auditory (re)habilitation course attended a parent panel presentation during their regularly scheduled face-to-face class. Five parents of children with diverse hearing differences and diverse technology, communication, and educational choices participated on the panel as guest speakers via the Zoom platform. Students completed written reflections based on Rolfe's reflective framework. Written reflections were downloaded from Canvas and de-identified prior to uploading to NVivo software for coding, utilizing an inductive grounded theory coding strategy coupled with content analysis.

Findings: This study underscores the effectiveness of written reflections as an effective andragogical learning model. Through reflective practice, students gained a deeper understanding of their experiences, values, and learning journeys, enhancing their competency in pediatric audiology and auditory (re)habilitation. Students articulated previous knowledge and learning experiences, utilized newfound insights from exposure to the parent panel of shared lived experiences, and connected this knowledge with future clinical applications.

Conclusions: Key findings underscore the effectiveness of reflective practice as an andragogical learning model, facilitating the integration of prior experiences with new knowledge. Moreover, it aids the transition of the professional journey from the familiar to the unfamiliar, demonstrating the impact of combining real-world lived experiences to reinforce and highlight classroom topics. Additionally, reflective practice enhances professional efficacy by valuing patient/parent perspectives regarding clinical care and aligning with evidence-based principles.

Purpose: The purpose of this study was to determine whether providing realistic auditory or somatosensory cues to spatial location would affect measures of vestibulo-ocular reflex gain in a rotary chair testing (RCT) context.

Method: This was a fully within-subject design. Thirty young adults age 18-30 years (16 men, 14 women by self-identification) completed sinusoidal harmonic acceleration testing in a rotary chair under five different conditions, each at three rotational frequencies (0.01, 0.08, and 0.32 Hz). We recorded gain as the ratio of the amplitude of eye movement to chair movement using standard clinical procedures. The five conditions consisted of two without spatial information (silence, tasking via headphones) and three with either auditory (refrigerator sound, tasking via speaker) or somatosensory (fan) information. Two of the conditions also included mental tasking (tasking via headphones, tasking via speaker) and differed only in terms of the spatial localizability of the verbal instructions. We used linear mixed-effects modeling to compare pairs of conditions, specifically examining the effects of the availability of spatial cues in the environment. This study was preregistered on Open Science Framework (https://osf.io/2gqcf/).

Results: Results showed significant effects of frequency in all conditions (p < .05), but the only pairs of conditions that were significantly different were those including tasking in one condition but not the other (e.g., tasking via headphones vs. silence). Post hoc equivalence testing showed that the lack of significance in the other comparisons could be confirmed as not meaningfully different.

Conclusions: These findings suggest that the presence of externally localizable sensory information, whether auditory or somatosensory, does not affect measures of gain in RCT to any relevant degree. However, these findings also contribute to the increasing body of evidence suggesting that mental engagement ("tasking") does increase gain whether or not it is provided via localizable instructions.

Purpose: Cochlear implant device use, quantified by hearing hours percentage (HHP), is a known variable that impacts pediatric spoken language outcomes. Isolating specific factors that impact HHP could help clinicians intervene to reduce the implications of barriers and amplify the positive facets. The aim of this study is to identify variables that predict HHP in children.

Method: A retrospective chart review was completed using data collected from 2019 to 2023. Subjects were included if they were under the age of 18 years at the time of data collection and had data logging recorded in the clinical patient database. A mixed-effects model weighed the influence of year of the clinical visit (2019, 2020, 2021, 2022, and 2023), race/ethnicity (White, African American, Asian, Hispanic, Mixed Race, or Other), listener type (bilateral simultaneous, sequential, bimodal, unilateral hearing loss, or unilateral listener; one cochlear implant and a contralateral deaf ear), insurance type (private, Medicaid, or military, or none), age at surgery, presence of autism spectrum disorder (ASD) or an intellectual development delay (IDD), and age at test on HHP.

Results: There were a total of 5,106 data points from 958 subjects. The mean HHP of the cohort was 64.2% (SD = 26.94%). Lower HHP was associated with the presence of IDD or ASD, use of Medicaid, and older age at surgery. HHP increased with age. Subjects of color did not have a significantly different HHP than those who were White. There was an interaction between year of data collection and listener type. Each listener type's HHP was impacted differently by the year of data collection; however, years of the COVID-19 pandemic yielded lower HHP for all listener types.

Conclusions: The group mean of 64.9% is lower than the recommended 80% HHP goal, indicating that pediatric cochlear implant recipients have slightly more than half the access to sound as their age-matched typically hearing peers. Several variables that impact HHP were identified in this study. Cochlear implant teams can utilize these data to support vulnerable patients to increase HHP. Additional investigation is needed to determine what interventions most effectively improve HHP.

Background: Benign paroxysmal positional vertigo (BPPV) patients may experience balance problems in various environmental conditions other than positional dizziness. Therefore, there is a need to investigate the postural control abilities and the ability to use sensory inputs in BPPV patients in different conditions.

Objective: The aim of this study was to examine the postural control performance of middle-aged adult BPPV patients in easy and difficult balance tasks, the effect of vestibular stimulation on the maintenance of balance, and the risk of falling, by posturographic evaluation in various conditions.

Method: A total of 26 patients diagnosed with posterior canal BPPV and 26 controls were included in the study. Sensory Organization Test (SOT), Vestibular Stimulation Test (VST), and fall risk assessment (FRA) were applied to the participants, respectively.

Results: Significant difference was observed in SOT medio-lateral (ML) plane in Conditions 2 and 5 (p < .05). A significant difference was observed in the vestibular score in the SOT ML plane. No significant difference was observed in VST test scores (p > .05). In the FRA test, a significant difference was observed in the energy and gain parameters in the anterio-posterior plane (p < .05).

Conclusions: The current study examined postural control abilities of patients with BPPV in extensive external conditions and in both planes, using various sensory perturbations and stimulation. It was thought that while BPPV patients were in the active phase of the disease, their postural control skills in the ML plane decreased and they might be at risk of falling.

Purpose: The purpose of this study was to evaluate the benefits of a Bluetooth self-fitting device using an in situ hearing screening test and self-fitting processes.

Method: Thirty Mandarin-speaking individuals (16 men and 14 women) with mild-to-moderate hearing loss participated in this study. The hearing screening test was conducted using neckband earphones of a Bluetooth self-fitting device controlled by a smartphone app. The hearing screening tests were compared with the pure-tone audiometry in an audiometric booth. The amplification benefits of the self-fitting program-aided condition were evaluated and compared with those of unaided and preset program-aided conditions using the Mandarin Hearing in Noise Test (MHINT) and questionnaires.

Results: The pure-tone audiometry and hearing screening test results exhibited strong positive correlations at all test frequencies. In the environment with 90° noise, the sentence reception thresholds (SRTs) obtained for the self-fitting program-aided condition were significantly lower (p = .032) than those obtained for the unaided condition, whereas no significant difference was observed between the preset program-aided and the unaided conditions. Moreover, the participants' satisfaction ratings for the devices were consistent with their MHINT results, with a strong positive correlation observed between satisfaction with self-fitting and user satisfaction in smartphone app's control, functionality, and learning. Younger participants were significantly more satisfied in learning to use the app.

Conclusions: Bluetooth self-fitting devices can be used for simplified in situ hearing screenings with a sensitivity of 90.4%. The satisfaction ratings and improvements in SRTs indicate significant clinical benefits of the self-fitting program compared with the preset program, particularly in the 90°-noise environments.

Purpose: The aim of the current scoping review is to identify the studies reporting ototoxicity monitoring in individuals with head and neck cancer (HNC) undergoing radiation therapy and/or chemoradiation therapy across the world. The specific objectives were to identify and report the test protocol used, identify the most common timeline of follow-up, and identify barriers and facilitators influencing the implementation of the monitoring program.

Method: A comprehensive search was conducted across six electronic databases, including PubMed, Embase, Web of Science, Scopus, Google Scholar, and ProQuest. The scoping review method adhered to relevant guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) and frameworks. The database search was carried out by two independent researchers, and studies were selected based on specific inclusion and exclusion criteria.

Results: This scoping review identified 13 studies that fulfilled the inclusion criteria of this study. Only one study reported findings from the perspective of ototoxicity monitoring. Another study explicitly mentioned that ototoxicity monitoring was a standard of care in their hospital. Only one study reported using the relevant guidelines for monitoring ototoxicity. Specialized tests such as high-frequency audiometry, distortion product otoacoustic emissions, and vestibular tests were rarely used. Ototoxicity monitoring was influenced by awareness-related factors, technical factors, treatment-related factors, and organizational factors.

Conclusions: Research on ototoxicity monitoring programs is in its early stages, highlighting the need for standardized practices and multidisciplinary collaboration to enhance health care services for HNC patients. A standardized approach, improved awareness, and the incorporation of patient perspectives are crucial to enhancing ototoxicity monitoring in HNC patients.

Purpose: Hearing aids play a pivotal role in mitigating the impact of hearing loss, yet their adoption and consistent usage remains suboptimal. Understanding the hearing aid needs of individuals with hearing loss is important to support uptake, use, and outcomes. The current study describes users' perspectives on how hearing aids can be improved.

Method: A cross-sectional, qualitative, content analysis design was used for an open-ended question from an online survey, exploring user perspectives on hearing aid improvements. Participants were adult hearing aid users in the United States, surveyed from the HearingTracker and Lexie Hearing user database.

Results: A total of 628 participants (M_age = 66 years) were surveyed. The majority of participants used bilateral, behind-the-ear hearing aids that were obtained either through a hearing health care professional or online. Three domains, highlighting areas for hearing aid improvement, were identified. (a) The hearing aid features domain described user issues surrounding physical appearance and fit, general features, streaming, battery functionality, adjustments, smartphone applications, and hearing aid-related accessories. There was dissatisfaction with aesthetics and functionality, with a notable desire for improvements in physical appearance and fit (n = 161), and features to improve self-efficacy. (b) The sound quality domain described user issues surrounding sound perception and difficult situations. Participants highlighted unmet needs for clarity, especially in noisy environments (n = 143). (c) The service-delivery domain described user issues surrounding audiology services and general satisfaction, with criticisms centered on the high cost of hearing aids (n = 193) and the credibility of hearing health care professionals.

Conclusions: Hearing aid users appreciated current technological advances but expressed a need for improvements, to better align devices with their requirements. Key areas included physical aesthetics, user control over device adjustments, sound clarity, cost accessibility, and trust between the user and hearing health care professional. Future designs should focus on features enhancing user autonomy and self-efficacy.

Purpose: Audiological services are underused, possibly because patients need to drive long distances to see a provider. In this study, we measured the association of drive times to the nearest audiologist with population density, income, ethnicity, race, and distance to the nearest audiology graduate program.

Method: Drive times for each census block group to the nearest audiologist were measured using census data, the National Provider Identifier Registry, and a geographic analyzing tool called ArcGIS for all block groups within the United States. The association between drive times and population density, income, ethnicity, race, and audiology program distance was evaluated with a population density-matched case-control study and multiple linear regression analyses.

Results: Approximately 5.29 million Americans need to drive at least 1 hr to visit their closest audiologist. The 10% most rural-dwelling Americans drive an average of 33.8 min. The population density-matched case-control study demonstrated that percent below poverty, percent identifying as Hispanic, and travel times to the nearest audiology program were all significantly higher in census block groups with high drive times to the nearest audiologist. An average of 7.96% of individuals in census block groups with low drive times identified as Hispanic, but 18.8% identified as Hispanic in high drive time groups. The multiple linear regression showed that the effect of demographics and distance to the nearest audiology program was highest in rural areas. In both analyses, adjusting for poverty did not drastically change the effect of percent identifying as Hispanic on drive times.

Conclusions: Long drive times restrict access to audiological care for those who live in rural areas. This restriction disproportionately affects those in rural areas who identify as Hispanic or have low income.

Purpose: Cauliflower ear in wrestlers can lead to hearing impairment. This study primarily aims to assess the hearing of wrestlers with bilateral cauliflower ears and determine their external ear canal (EEC) resonance frequencies. Our second aim is to evaluate their hearing quality, speech, and spatial perception.

Method: This study included 28 male wrestlers aged 18-35 years with bilateral cauliflower ears, as well as 27 male participants in the control group with no wrestling history. The participants' hearing thresholds were determined across the frequency range of 125-16000 Hz for air-conduction and 500-4000 Hz for bone conduction. EEC resonance frequencies were measured. Additionally, all participants completed the Turkish version of the Speech, Spatial, and Qualities of Hearing Scale (SSQ) questionnaire.

Results: Wrestlers with cauliflower ears exhibited significantly higher hearing thresholds, particularly at frequencies above 4000 Hz (p < .05). Analysis of EEC resonance showed a shift to higher frequencies in the second resonance peak of the right ear (p < .001) and the first resonance peak of the left ear (p = .045). SSQ scores revealed that wrestlers had higher spatial perception (p = .046), hearing quality (p = .004), and general scores (p = .042) in comparison to the control group.

Conclusions: Blunt traumas in wrestlers, leading to cauliflower ear, can result in hearing loss. Moreover, deformities in the external ear affect the resonance frequencies of the EEC. Therefore, it is crucial to advocate for the use of ear protection equipment among wrestlers. When fitting hearing aids, attention should be given to changes in the EEC resonance frequency.

Purpose: Inspired by a preliminary survey of the Scholarship of Teaching and Learning (SoTL) literature conducted by Friberg et al. (2014), the current study aimed to expand the original study's findings-that SoTL was rarely published in the communication sciences and disorders (CSD) literature from 2009 to 2013-to the subsequent 8-year period (2014-2021). The latter period was of particular relevance considering the dissolution of one American Speech-Language-Hearing Association (ASHA)-affiliated publication and the addition of another non-ASHA-affiliated publication during that time.

Method: Ten peer-reviewed CSD journals and the articles published in them were identified via a survey of the literature that used narrowly defined criteria developed in collaboration with a librarian. Five trained CSD graduate student raters compared a definition of SoTL to article abstracts to determine whether each should have been categorized as SoTL. Part 1 of the study investigated an 8-year time span, Part 2 investigated the remaining nine journals in the subsequent 5 years, and Part 3 investigated publication rates of SoTL in Teaching and Learning in Communication Sciences & Disorders (TLCSD) alone.

Results: Part 1 of the study revealed that publication rates of SoTL were extremely low in the 10 surveyed CSD journals in the 8-year time span investigated. A similar and diminishing trend was found in Part 2. Even smaller percentages of journals were dedicated to SoTL. Part 3 confirmed that relatively large amounts of CSD-specific SoTL have been published in TLCSD since its inception in 2017.

Conclusions: As of 2021, SoTL articles continued to be uncommonly published in CSD journals. Until recently, scholarly teachers attempting to apply SoTL in the classroom had limited resources. Beginning in 2017, TLCSD has provided an outlet for SoTL, whereas other CSD journals seem to have published less of it. Reform of publication, peer review, tenure, and promotion policies and procedures is called for so that SoTL might be included as a valid scientific endeavor.
