Purpose: The aim of this study was to investigate the short- and long-term effects of a new cognitive sound exposure therapy (CSET) in patients with hyperacusis.

Method: A new therapy was developed to reduce hyperacusis using sound exposure combined with breathing and relaxation strategies from both acceptance and commitment therapy and cognitive behavioral therapy. Patients who were referred to the Speech and Hearing Centers located in Hengelo and Zwolle in the Netherlands and aged ≥ 18 years with hyperacusis as main complaint and no or mild hearing loss were included in this study. Patients were seen for CSET between June 2020 and August 2022. The sessions took place biweekly. Sessions ended when exposure reached a level with a maximum of 70-80 dB SPL. Short-term effects between the start and the end of therapy were based on tolerable level of sound exposure (dB SPL), subjective-level hinderance of hyperacusis, and sensitivity to sound using the Hyperacusis Questionnaire (HQ). The long-term effect was based on HQ 6 months after the end of therapy. Linear mixed-effects and regression models were applied to study outcomes over time.

Results: In total, 30 patients, 15 men and 15 women, aged between 24 and 76 years were included in this study. The mean number of sessions during therapy was 6 and ranged between 4 and 8. Results showed an increase of exposure level (mean change was +23.7 dB with an SD of 7.9, p < .001), a decrease in sensitivity to daily sounds (mean [SD] change was -1.6 [2.1], p < .001), and a decrease in HQ (mean [SD] change was -9.8 [4.9], p < .001), between the start and the end of therapy. There was no significant change in HQ after the end of therapy and 6 months later; mean (SD) change was 0.2 (4.3), p = .81.

Conclusions: The evaluation of CSET indicated a decrease in short- and long-term sensitivity to sound in patients with hyperacusis. Additionally, CSET has shown a positive impact, not only for the sounds used in the therapy sessions but also in transferring benefits to everyday sounds. The results of combining psychoeducation, sound exposure, and counseling are promising and warrant further evaluation.

Purpose: The objective of this study was to determine the normative vestibulo-ocular reflex gain output values of the computerized rotational head impulse test (crHIT) with stationary visual targets (earth bound) in healthy participants in each decade age band of life: 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, and 70+ years.

Method: Seventy-seven community-dwelling participants (10-85 years of age) with normal lateral semicircular canal (SCC) functioning and no symptoms or history of vestibular dysfunction were recruited through convenience sampling and assessed with the crHIT using stationary targets. These participants were assessed using two standard protocols in a randomized order.

Results: Results from 77 participants (M _age = 46 years; 43 women, 34 men) were analyzed. Pearson's correlation coefficient and simple linear regression indicated a statistically significant relationship between crHIT gain output and age (p > .05) for right gain, 1030°/s², and left gain, 1005°/s². Although a statistically significant relationship was found, the slope was minor, demonstrating that the clinical effect of age on crHIT gain output was insignificant. Furthermore, no statistically significant relationship exists between crHIT gain output and gender (p > .05). Age-dependent normative data were calculated using the 2.5th and 97.5th confidence interval (CI) percentile method. The responses of angular vestibulo-ocular reflex (aVOR) gain values for crHIT are expected to occur within the range for lower limit reference interval (RI) of 0.85-0.9 and upper limit RI of 1.11-1.18 for 1030°/s² and lower limit RI of 0.86-0.92 and upper limit RI of 1.13-1.16 for 1005°/s². It can be expected that 90% CI of the population with normal lateral SCC functioning will have aVOR gain values that fall within this range.

Conclusion: Despite a statistically significant relationship that exists with aVOR gain output and age, the changes are minor, declining by 0.0088 units per 10 years, justifying the same normative data for all decade age bands.

Purpose: The purpose of the present review was to report the effectiveness of Epley maneuver compared to other manual repositioning maneuvers (RM) for treatment of posterior benign paroxysmal positional vertigo (P-BPPV). A systematic search of PubMed, Embase, and the Cochrane Library was conducted up until June 30, 2023.

Results: Primary outcomes focused on complete resolution of vertiginous symptoms measured by either a Visual Analog Scale (VAS) or the Dix-Hallpike (DH) test. Secondary outcomes included conversion of a positive DH test to a negative DH test exclusively looking at positional nystagmus and assessment of side effects (cervical/back pain, posttreatment dizziness, and nausea). Both outcomes were assessed within a maximum of 4-week follow-up. Following systematic search and review, nine randomized controlled trials (RCTs; p = .413) were found. The studies reported on the effectiveness of the Epley maneuver compared to three other specific RM: Semont, Li, and Gans maneuvers. Results revealed a low to very low certainty of evidence. With the primary outcomes, Epley maneuver was superior to Gans maneuver 24-hr posttreatment but not after 1 week. No significant differences were found between the remaining maneuvers.

Conclusions: In summary, evidence of low to very low certainty indicates that Epley maneuver is comparable with Semont, Gans, and Li maneuvers for vertiginous symptoms in patients with P-BPPV. Further high-quality studies are needed.

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: 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: 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.
