ABSTRACT
Participation in complex listening situations such as group conversations in noisy environments sets high demands on the auditory system and on cognitive processing. Reports of hearing-impaired people indicate that strenuous listening situations occurring throughout the day lead to feelings of fatigue at the end of the day. The aim of the present study was to develop a suitable test sequence to evoke and measure listening effort (LE) and listening-related fatigue (LRF), and, to evaluate the influence of hearing aid use on both dimensions in mild to moderately hearing-impaired participants. The chosen approach aims to reconstruct a representative acoustic day (Time Compressed Acoustic Day [TCAD]) by means of an eight-part hearing-test sequence with a total duration of approximately 2½ h. For this purpose, the hearing test sequence combined four different listening tasks with five different acoustic scenarios and was presented to the 20 test subjects using virtual acoustics in an open field measurement in aided and unaided conditions. Besides subjective ratings of LE and LRF, behavioral measures (response accuracy, reaction times), and an attention test (d2-R) were performed prior to and after the TCAD. Furthermore, stress hormones were evaluated by taking salivary samples. Subjective ratings of LRF increased throughout the test sequence. This effect was observed to be higher when testing unaided. In three of the eight listening tests, the aided condition led to significantly faster reaction times/response accuracies than in the unaided condition. In the d2-R test, an interaction in processing speed between time (pre- vs. post-TCAD) and provision (unaided vs. aided) was found suggesting an influence of hearing aid provision on LRF. A comparison of the averaged subjective ratings at the beginning and end of the TCAD shows a significant increase in LRF for both conditions. At the end of the TCAD, subjective fatigue was significantly lower when wearing hearing aids. The analysis of stress hormones did not reveal significant effects.

BACKGROUND: Incomplete partition type II (IP-II) malformation is often accompanied by a large vestibular aqueduct (LVA). In IP anomalies, the patient's auditory rehabilitation requirements are decided according to the presence of inner ear structures and the degree of hearing loss (HL). There has been limited research on auditory rehabilitation (AR) requirement selection in patients diagnosed with IP-II and LVA. This study investigated the typical characteristics of HL and AR choices in patients diagnosed with IP-II and LVA. METHODS: Patients with IP-II and LVA (n=55; 25 women and 30 men) were identified, and audiological evaluations were performed. The patient's demographic characteristics, the type and degree of HL, the AR method, age at diagnosis, and educational status were retrospectively compared. RESULTS: The distribution of our 55 patients according to cochlear implants, hearing aids (HA), and bimodal applications was 29.1% (n=16), 43.6% (n=24), and 27.3% (n=15), respectively. Statistical analyses using chi-square tests found no significant differences in the incidence of dizziness/imbalance, tinnitus, HL progression, or the degree and onset of HL among the patients. CONCLUSION: The data revealed different audiological characteristics among patients with IP-II and LVA, as well as different AR solutions. The most widely used AR modality was found to be HA. Prediction of sudden versus progressive HL development among patients is challenging, and the characteristics of IP-II vary. Therefore, they should be interpreted with caution.

During the last decade, there has been a move towards consumer-centric hearing healthcare. This is a direct result of technological advancements (e.g., merger of consumer grade hearing aids with consumer grade earphones creating a wide range of hearing devices) as well as policy changes (e.g., the U.S. Food and Drug Administration creating a new over-the-counter [OTC] hearing aid category). In addition to various direct-to-consumer (DTC) hearing devices available on the market, there are also several validated tools for the self-assessment of auditory function and the detection of ear disease, as well as tools for education about hearing loss, hearing devices, and communication strategies. Further, all can be made easily available to a wide range of people. This perspective provides a framework and identifies tools to improve and maintain optimal auditory wellness across the adult life course. A broadly available and accessible set of tools that can be made available on a digital platform to aid adults in the assessment and as needed, the improvement, of auditory wellness is discussed.

BACKGROUND: Mobile health (mHealth) solutions can improve the quality, accessibility, and equity of health services, fostering early rehabilitation. For individuals with hearing loss, mHealth apps might be designed to support the decision-making processes in auditory diagnostics and provide treatment recommendations to the user (eg, hearing aid need). For some individuals, such an mHealth app might be the first contact with a hearing diagnostic service and should motivate users with hearing loss to seek professional help in a targeted manner. However, personalizing treatment recommendations is only possible by knowing the individual's profile regarding the outcome of interest. OBJECTIVE: This study aims to characterize individuals who are more or less prone to seeking professional help after the repeated use of an app-based hearing test. The goal was to derive relevant hearing-related traits and personality characteristics for personalized treatment recommendations for users of mHealth hearing solutions. METHODS: In total, 185 (n=106, 57.3% female) nonaided older individuals (mean age 63.8, SD 6.6 y) with subjective hearing loss participated in a mobile study. We collected cross-sectional and longitudinal data on a comprehensive set of 83 hearing-related and psychological measures among those previously found to predict hearing help seeking. Readiness to seek help was assessed as the outcome variable at study end and after 2 months. Participants were classified into help seekers and nonseekers using several supervised machine learning algorithms (random forest, naïve Bayes, and support vector machine). The most relevant features for prediction were identified using feature importance analysis. RESULTS: The algorithms correctly predicted action to seek help at study end in 65.9% (122/185) to 70.3% (130/185) of cases, reaching 74.8% (98/131) classification accuracy at follow-up. Among the most important features for classification beyond hearing performance were the perceived consequences of hearing loss in daily life, attitude toward hearing aids, motivation to seek help, physical health, sensory sensitivity personality trait, neuroticism, and income. CONCLUSIONS: This study contributes to the identification of individual characteristics that predict help seeking in older individuals with self-reported hearing loss. Suggestions are made for their implementation in an individual-profiling algorithm and for deriving targeted recommendations in mHealth hearing apps.

OBJECTIVE: People with hearing handicap have to use a whole range of strategies to cope with everyday challenges - they have to self-manage their hearing impairment. While the support of self-management is well established in foreign language audiological rehabilitation programs, there are no recommendations in Germany yet. Therefore, the aim of this systematic review is first to give an overview of existing self-management interventions for people with hearing handicap and then to suggest possible applications in the German care system. METHODS: A systematic literature search was conducted on PubMed. The articles dealt with self-management interventions for people with hearing impairment. This eligibility criterion was applied to titles, abstracts, and full texts. If eligible, information on the publication, intervention, and evaluation were extracted and qualitatively summarized. The methodological quality of studies was investigated using the NIH assessment tool for interventional studies. RESULTS: 23 papers could be included and show a high heterogeneity regarding methodological quality, applied intervention, and design of evaluation. The interventions pursuing various goals include a wide range of content (e. g., communication improvement or psychosocial aspects) and have been implemented on a group-based, individual-based, or self-administered level. Despite a few studies that failed to demonstrate intervention effects, most evaluations found positive ef-fects of the intervention on hearing impairment, psychological well-being, and communication. DISCUSSION: The included studies present a high heterogeneity with regard to methodological quality, the intervention conducted, and the evaluation design. Therefore, a summary of the findings was only possible in a qualitative manner. Possibilities of adapting existing intervention programs as well as chances and limits of an implementation in the German health care system are to be discussed in the following. CONCLUSION: Overall, interventions including self-management support seem to be a profitable complement to sole technical device supply and should be further fostered in German-speaking countries as well.

OBJECTIVE: The hearing aid adoption rate among older adults in Japan is lower than that in other developed countries. Herein, a survey was conducted to identify this bottleneck and develop countermeasures. This study aimed to examine whether raising awareness of the relationship between hearing loss and dementia is significant for hearing tests and adopting hearing aids. METHODS: A questionnaire was administered to participants aged 65 or older who visited a general hospital to determine the background factors (1) for a recent history of hearing tests, (2) for the desire to visit an otolaryngologist and have a hearing test, (3) for recognizing the hearing loss-dementia relationship, and (4) for adopting hearing aids. RESULTS: A total of 517 patients (mean age, 78.06; SD 6.97), representing 2.4% of the region's older-adult population, participated in the survey. A history of hearing tests within five years was significantly associated with recognizing the hearing loss-dementia relationship (adjusted OR 2.36, 95% CI 1.49-3.72). The desire to visit an otolaryngologist or have a hearing test was significantly associated with recognizing the hearing loss-dementia relationship (adjusted OR 1.70, 95% CI 1.02-2.85). Moreover, 39.3% were aware of the hearing loss-dementia relationship. The significant associated factors were being female (OR 2.50, 95% CI 1.64-3.81) and having interpersonal hobbies (OR 1.66, 95% CI 1.11-2.49). The significant background factors for adopting hearing aids were older age (OR 6.95, 95% CI 1.90-25.40), self-reported severe hearing impairment (OR 5.49, 95% CI 2.55-11.80), and living alone (OR 2.63, 95% CI 1.18-5.89). Recognizing the hearing loss-dementia relationship was not a significant factor. CONCLUSION: Raising awareness of the hearing loss-dementia relationship was not associated with adopting hearing aids for self-reported hearing impairments. However, it may be associated with otolaryngology visits and hearing tests. Thus, steps like hearing screening for older adults are also essential.

This study examines the usability of communication-assistive applications for hearing-impaired users, with a focus on enhancing user experience and promoting social inclusion. Although such applications have been developed and evaluated previously, interface designs that consider the intimacy needs of hearing-impaired users remain under-explored. We performed a comprehensive usability evaluation employing a mixed-method approach, which involved hearing-impaired individuals as well as field experts. The findings revealed areas for improvement in the design, validated the feasibility of implementing these applications, and emphasized the importance of incorporating the unique needs and preferences of hearing-impaired users. Furthermore, this paper discusses the importance of introducing guidelines and evaluation scales for the "Design for Emotion and Life Knowledge" levels to facilitate smooth and effective human-computer interactions. Such measures will promote the development of intelligent assistive technologies that reflect the qualitative needs of people with disabilities and contribute to social rights for hearing-impaired users. With the growing demands of artificial-intelligence-powered assistive technologies, the inclusion of individuals with disabilities in the design and research process is anticipated to increase. In future, studies should be conducted to blend the culturally shared experiences and emotional bonds expressed by users (having mild-to-severe hearing impairment) with the design and development process of assistive devices or services.

BACKGROUND: The role of patients in healthcare research is slowly evolving, although patient roles in the research process are limited. This paper reports on a patient-led research project aiming to develop a musical hearing training programme for patients with a cochlear implant (CI): the Musi-CI programme. A CI is an inner ear prosthesis that allows people with severe hearing loss to hear. However, while speech can be understood, CI users cannot fully enjoy music or feel aversion to it. The Musi-CI programme aims to reduce this music aversion to ultimately improve music enjoyment and social participation. The development of the Musi-CI programme was supported by a consortium of professionals in CI rehabilitation and research. The aim of this paper is to describe and evaluate the Musi-CI programme development process and its impact on professional CI rehabilitation and research. METHODS: Programme development was described using a 3-layered process model of action research, distinguishing the CI user process, the healthcare professional process and the research process. To evaluate perceptions on the programme development process, consortium partners provided written comments and participated in a reflexive evaluation session that was video-recorded. Reflexive evaluation aims for collective learning and strengthening collaboration among participants. Written comments and video data were analysed using template analysis. RESULTS: The involvement of an expert by experience was perceived as challenging but rewarding for all consortium partners, opening up new perspectives on CI-rehabilitation practice and research. Data analysis revealed two themes on the programme development process, professional space and acknowledgement, and two themes on the outcomes on CI rehabilitation and research: critical reflection and paradigm shift. CONCLUSION: Experts by experience represent a different knowledge domain that may contribute to change in rehabilitation and research. PATIENT OR PUBLIC CONTRIBUTION: The development of the programme was initiated by a professional musician and CI user who organized the funding, had a leading role throughout the research process, including the write-up of the results, and co-authored this paper.

PURPOSE: The study examines the effect of hearing loss and hearing aid (HA) amplification on the conversational dynamics between hearing-impaired (HI) and normal-hearing (NH) interlocutors. Combining data from the current and a prior study, we explore how the speech levels of both interlocutors correlate and relate to HI interlocutors' degree of hearing loss. METHOD: Sixteen pairs of younger NH and elderly HI interlocutors conversed in quiet, with the HI interlocutor either unaided or wearing HAs. We analyzed the effect of hearing status and HA amplification on the conversational dynamics, including turn-taking times (floor-transfer offsets), utterance lengths, and speech levels. Furthermore, we conducted an in-depth analysis of the speech levels using combined data sets from the current and previously published data by Petersen, MacDonald, and Sørensen (2022). RESULTS: Unaided HI interlocutors were slower and more variable at timing their turns, but wearing HAs reduced the differences between the HI and NH interlocutors. Conversations were less interactive, and pairs were slower at solving the conversational tasks when the HI interlocutor was unaided. Both interlocutors spoke louder when the HI interlocutor was unaided. The speech level of the NH interlocutors was related to that of the HI interlocutors, with the HI speech levels also correlating with their own degree of hearing loss. CONCLUSIONS: Despite typically being unchallenging for HI individuals, one-on-one conversations in quiet were impacted by the HI interlocutor not wearing HAs. Additionally, combining data sets revealed that NH interlocutors adjusted their speech level to match that of HI interlocutors.

OBJECTIVE: The aim of this study was to investigate the effect of a visual cognitive additional task on balance performance in young adults with hearing aids (HAs). METHOD: Twenty young adult HA users and 20 controls were recruited for the study. Participants were asked to stand on a force plate using computerized dynamic posturography and perform a Sensory Organization Test (SOT) as a balance task under single-task (ST) and dual-task (DT) conditions. The DT condition involved performing a visual cognitive task (Backward Digit Recall) while maintaining balance. Balance performance was measured using equilibrium scores under four different conditions. RESULTS: The results showed that SOT scores of HA users decreased significantly in the DT compared to the ST (p of Condition 1: < .001; p of Condition 4: < .001; p of Condition 6: = .001). HA users' SOT scores in the DT condition were statistically significantly lower than controls (p of Condition 1: < .003; p of Condition 4: < .009; p of Condition 6: = .004). This suggests that the presence of a visual cognitive additional task has a negative impact on balance performance in young adults with HAs. CONCLUSIONS: These findings highlight the importance of considering the impact of cognitive tasks on balance performance in young adults with HAs. Further studies should investigate the specific needs of hearing loss patients in multitasking conditions, including age, degree of hearing loss, and cognitive ability, to develop effective interventions to reduce the risk of falls.

PURPOSE: Technology-enabled care, including the use of mobile health (mHealth), is emerging as a viable hearing health care delivery method. While the integration of mHealth with adult populations currently supports a wide array of hearing services, a better understanding of the implementation across the lifespan is needed. Literature surrounding the unique population of adolescent hearing aid users is currently lacking. Research is needed to highlight factors important to the use and clinical integration of mHealth hearing aid applications (apps) with adolescents. This study explored two primary objectives: (a) audiologists' perceptions around the use of mHealth apps to enable collaborative, child-inclusive hearing aid personalization, and (b) person-centered ideation around potential app design components to benefit users aged 12 to 17 years. METHOD: Twelve audiologists participated in virtual synchronous focus groups, across three group sessions using Cisco Webex. Sessions were recorded, transcribed, and analyzed using an inductive, codebook thematic analysis approach. RESULTS: Six main themes resulted from group discussion analyses: (a) client candidacy: characteristics impacting suitability for mHealth use; (b) clinical implementation: organizational, professional, or patient-level strategies for mHealth adoption; (c) collaboration: the use of two or more individuals working together; (d) empowerment: process of acquiring and using knowledge, skills, and strategies; (e) remote technology: technologies enabling remote hearing aid personalization; and (f) application functionality and design: features and characteristics important to an adolescent-focused app. CONCLUSIONS: Findings identified the potential for clinical integration of hearing aid apps with adolescents in a collaborative care model, including consideration of child-specific use patterns, outcomes, and key design and technology components to support real-world implementation and use. Results may guide development and tailoring efforts around existing and future hearing aid apps for use with adolescent populations.

Background: The assumption that hearing rehabilitation could improve quality of life and reduce dementia risk in people with hearing loss is a subject that needs further studies, especially clinical trials. It is necessary to determine the effects of hearing aid use, as part of hearing rehabilitation, among people diagnosed with dementia. Objective: To systematically review the literature to evaluate the effects of hearing aid use on cognition and quality of life of people with dementia. Methods: Protocol for this systematic review was registered (CRD42023387187). The Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Scopus, CINAHL, and Web of Science databases, as well as grey literature, including Google Scholar and ResearchGate, were systematically searched for clinical trials using MeSH terms. The PICOS principle was used to develop the inclusion criteria: population (P): adults and older adults, individuals diagnosed with dementia and hearing loss; intervention (I): rehabilitation with hearing aids; control (C): not using a hearing aid; outcome (O): cognitive and/or quality of life assessment using validated tests; study design (S): clinical trial. Results: The initial search yielded 576 studies, five of which met the inclusion criteria for qualitative analyses. Two of the included studies were randomized clinical trials, and three were crossover clinical trials, demonstrating the lack of studies on the subject. Four studies included participants with Alzheimer's disease. Quality of life was found to improve with the use of hearing aids, and hearing rehabilitation was not shown to affect cognitive outcomes. Conclusions: Hearing aid use appears to have a positive impact on quality of life.

OBJECTIVE: The acoustic change complex (ACC) is a cortical auditory evoked potential (CAEP) and can be elicited by a change in an otherwise continuous sound. The ACC has been highlighted as a promising tool in the assessment of sound and speech discrimination capacity, and particularly for difficult-to-test populations such as infants with hearing loss, due to the objective nature of ACC measurements. Indeed, there is a pressing need to develop further means to accurately and thoroughly establish the hearing status of children with hearing loss, to help guide hearing interventions in a timely manner. Despite the potential of the ACC method, ACC measurements remain relatively rare in a standard clinical settings. The objective of this study was to perform an up-to-date systematic review on ACC measurements in children, to provide greater clarity and consensus on the possible methodologies, applications, and performance of this technique, and to facilitate its uptake in relevant clinical settings. DESIGN: Original peer-reviewed articles conducting ACC measurements in children (< 18 years). Data were extracted and summarised for: (1) participant characteristics; (2) ACC methods and auditory stimuli; (3) information related to the performance of the ACC technique; (4) ACC measurement outcomes, advantages, and challenges. The systematic review was conducted using PRISMA guidelines for reporting and the methodological quality of included articles was assessed. RESULTS: A total of 28 studies were identified (9 infant studies). Review results show that ACC responses can be measured in infants (from < 3 months), and there is evidence of age-dependency, including increased robustness of the ACC response with increasing childhood age. Clinical applications include the measurement of the neural capacity for speech and non-speech sound discrimination in children with hearing loss, auditory neuropathy spectrum disorder (ANSD) and central auditory processing disorder (CAPD). Additionally, ACCs can be recorded in children with hearing aids, auditory brainstem implants, and cochlear implants, and ACC results may guide hearing intervention/rehabilitation strategies. The review identified that the time taken to perform ACC measurements was often lengthy; the development of more efficient ACC test procedures for children would be beneficial. Comparisons between objective ACC measurements and behavioural measures of sound discrimination showed significant correlations for some, but not all, included studies. CONCLUSIONS: ACC measurements of the neural capacity to discriminate between speech and non-speech sounds are feasible in infants and children, and a wide range of possible clinical applications exist, although more time-efficient procedures would be advantageous for clinical uptake. A consideration of age and maturational effects is recommended, and further research is required to investigate the relationship between objective ACC measures and behavioural measures of sound and speech perception for effective clinical implementation.

PURPOSE: To analyze the performance of auditory speech perception (PF) after cochlear implant (CI) replacement surgery and associations with age, times of use of the first CI, deprivation, recovery and use of the second device. METHODS: The retrospective study analyzed the medical records of 68 participants reimplanted from 1990 to 2016, and evaluated with PF performance tests, considering as a reference, the greater auditory capacity identified during the use of the first CI. Also analyzed were: Etiology of hearing loss; the reasons for the reimplantation; device brands; age range; sex; affected ear; age at first implant; time of use of the first CI, deprivation, recovery and use of the second device. The analyzes followed with the Chi-Square and Spearman, Mann-Whitney and Kruskal-Wallis tests (CI=95%; p≤0.05; Software SPSS®.v22). RESULTS: Most were children with hearing loss due to idiopathic causes and meningitis. Abrupt stoppage of operation was the most common cause for device replacement. Most cases recovered and maintained or continued to progress in PF after reimplantation. Adults have the worst recovery capacity when compared to children and adolescents. The PF capacity showed a significant association (p≤0.05) with: age at first implant; time of use of the first and second CI. CONCLUSION: Periodic programming and replacement of the device when indicated are fundamental for the maintenance of auditory functions. Being young and having longer use of implants represent advantages for the development of speech perception skills.
OBJETIVO: Analisar o desempenho da percepção auditiva da fala (PF) após cirurgia de substituição do implante coclear (IC) e identificar associações com a idade, tempos de uso dos dispositivos, privação e recuperação. MÉTODO: O estudo retrospectivo analisou os prontuários de 1990 a 2016 e considerou como referência o maior escore da capacidade auditiva identificada ao longo do uso do primeiro IC. Foram coletados dados epidemiológicos; etiologia; causas da substituição e marca dos dispositivos; classificação etária; idades no primeiro e segundo implante; tempos de utilização, privação e de recuperação da capacidade auditiva. Os dados foram avaliados por meio de testes estatísticos não paramétricos (IC=95%; p<0.05). RESULTADOS: Foram avaliados 68 participantes (31 adultos e 37 crianças), sendo 52,9% do sexo feminino e as principais etiologias da perda auditiva foram: idiopática (48,5%), infecciosa (33,8%) e outras causas não infecciosas (17,6%). A idade média verificada na implantação do primeiro e do segundo IC, foram: 102±143,4 e 178,9±173,4 meses. Os tempos médios de uso do primeiro IC, privação, recuperação e uso do segundo IC, foram respectivamente: (76,1±63,3); (2,8±2,4); (6,5±7,1); (75,6±48,3) meses. A substituição foi motivada principalmente pela parada abrupta de funcionamento (77,9%) e 85,3% dos participantes recuperaram a PF, que esteve significativamente associada à idade no primeiro IC, e os tempos de utilização dos dispositivos (p<0.05). CONCLUSÃO: A maior parte dos indivíduos submetidos ao reimplante conseguem recuperar e/ou continuar o desenvolvimento das habilidades auditivas. A idade mais jovem e o tempo de uso dos dispositivos são fatores que influenciam na capacidade de recuperação da PF em reimplantados.

The extent to which active noise cancelation (ANC), when combined with hearing assistance, can improve speech intelligibility in noise is not well understood. One possible source of benefit is ANC's ability to reduce the sound level of the direct (i.e., vent-transmitted) path. This reduction lowers the "floor" imposed by the direct path, thereby allowing any increases to the signal-to-noise ratio (SNR) created in the amplified path to be "realized" at the eardrum. Here we used a modeling approach to estimate this benefit. We compared pairs of simulated hearing aids that differ only in terms of their ability to provide ANC and computed intelligibility metrics on their outputs. The difference in metric scores between simulated devices is termed the "ANC Benefit." These simulations show that ANC Benefit increases as (1) the environmental sound level increases, (2) the ability of the hearing aid to improve SNR increases, (3) the strength of the ANC increases, and (4) the hearing loss severity decreases. The predicted size of the ANC Benefit can be substantial. For a moderate hearing loss, the model predicts improvement in intelligibility metrics of >30% when environments are moderately loud (>70â dB SPL) and devices are moderately capable of increasing SNR (by >4â dB). It appears that ANC can be a critical ingredient in hearing devices that attempt to improve SNR in loud environments. ANC will become more and more important as advanced SNR-improving algorithms (e.g., artificial intelligence speech enhancement) are included in hearing devices.

Background: Access to audiology services for older adults residing in sparsely populated regions is often limited compared to those in central urban areas. The geographic accessibility to follow-up care, particularly the influence of distance, may contribute to an increased risk of hearing aid abandonment. Objective: To assess the association between the home-to-healthcare-calibration-center distance and hearing aid abandonment among older adults fitted in the Chilean public health system. Methods: 455 patients who received hearing aids from two public hospitals in two regions were considered. Univariate and multivariate Poisson regression models with robust variance estimation were used to analyze the association between the geographical distance and hearing aid abandonment, accounting for confounding effects. Results: Approximately 18% of the sample abandoned the hearing aid, and around 50% reported using the hearing aid every day. A twofold increase in distance between home and the hearing center yielded a 35% (RR = 1.35; 95% CI: 1.04-1.74; p = 0.022) increased risk of hearing aid abandonment. Also, those in the second quintile had a 2.17 times the risk of abandoning the hearing aid compared to the first quintile (up to 2.3 km). Under the assumption that patients reside within the first quintile of distance, a potential reduction of 45% in the incidence of hearing aid abandonment would be observed. The observed risk remained consistent across different statistical models to assess sensitivity. Conclusion: A higher distance between the residence and the healthcare center increases hearing aid abandonment risk. The association may be explained by barriers in purchasing supplies required to maintain the device (batteries, cleaning elements, potential repairs, or maintenance).

The use of in-situ audiometry for hearing aid fitting is appealing due to its reduced resource and equipment requirements compared to standard approaches employing conventional audiometry alongside real-ear measures. However, its validity has been a subject of debate, as previous studies noted differences between hearing thresholds measured using conventional and in-situ audiometry. The differences were particularly notable for open-fit hearing aids, attributed to low-frequency leakage caused by the vent. Here, in-situ audiometry was investigated for six receiver-in-canal hearing aids from different manufacturers through three experiments. In Experiment I, the hearing aid gain was measured to investigate whether corrections were implemented to the prescribed target gain. In Experiment II, the in-situ stimuli were recorded to investigate if corrections were directly incorporated to the delivered in-situ stimulus. Finally, in Experiment III, hearing thresholds using in-situ and conventional audiometry were measured with real patients wearing open-fit hearing aids. Results indicated that (1) the hearing aid gain remained unaffected when measured with in-situ or conventional audiometry for all open-fit measurements, (2) the in-situ stimuli were adjusted for up to 30 dB at frequencies below 1000 Hz for all open-fit hearing aids except one, which also recommends the use of closed domes for all in-situ measurements, and (3) the mean interparticipant threshold difference fell within 5 dB for frequencies between 250 and 6000 Hz. The results clearly indicated that modern measured in-situ thresholds align (within 5 dB) with conventional thresholds measured, indicating the potential of in-situ audiometry for remote hearing care.

A vestibular schwannoma is a benign tumor; however, the schwannoma itself and interventions can cause sensorineural hearing loss. Most vestibular schwannomas are unilateral tumors that affect hearing only on one side. Attention has focused on improving the quality of life for patients with unilateral hearing loss and therapeutic interventions to address this issue have been emphasized. Herein, we encountered a patient who was a candidate for hearing preservation surgery based on preoperative findings and had nonserviceable hearing after the surgery, according to the Gardner-Robertson classification. Postoperatively, the patient had decreased listening comprehension and ability to localize sound sources. He was fitted with bilateral hearing aids, and his ability to localize sound sources improved. Although the patient had postoperative nonserviceable hearing on the affected side and age-related hearing loss on the unaffected side, hearing aids in both ears were useful for his daily life. Therefore, the patient was able to maintain a binaural hearing effect and the ability to localize the sound source improved. This report emphasizes the importance of hearing preservation with vestibular schwannomas, and the demand for hearing loss rehabilitation as a postoperative complication can increase, even if hearing loss is nonserviceable.

BACKGROUND: Hearing loss affects over 1.5 billion individuals globally, with significant implications for mental health. This study investigates the association between hearing aid use and mental health outcomes, by particularly focusing on depression and unmet mental health needs (UMHN), across a diverse international sample. METHODS: Utilizing data from the third wave of the European Health Interview Survey (EHIS), this study involved 17,660 participants with hearing impairment from 28 countries. The study examined the association between hearing aid use and mental health outcomes, including the likelihood of moderate and severe depression and UMHN due to lack of contact with general practitioners (GPs) and mental health specialists. Logistic regression models, adjusted for socio-demographic characteristics, health risk behaviours, and other relevant variables, were employed. Inverse probability weights were used to mitigate potential selection bias. RESULTS: Hearing aid usage was associated with significantly lower likelihoods of moderate depression (Odds Ratio [OR] = 0.58, 95%CI = [0.54, 0.63]) and severe depression (OR = 0.61, 95%CI = [0.55, 0.69]), compared to non-usage. Hearing aid usage was also associated with reduced UMHN due to lack of GP contact for moderate (OR = 0.82, 95%CI = [0.75, 0.89]) and severe depression (OR = 0.75, 95%CI = [0.59, 0.95]). The depression risk reductions were greater among females and higher-educated subgroups but lower in individuals aged ≥65 years. Income level and rurality also impacted UMHN due to the lack of GP contact. No associations were found between hearing aids and UMHN due to the lack of mental health specialist contact. CONCLUSIONS: Hearing aid adoption showed protective associations against mood disorders and lowered unmet primary mental healthcare needs. Tailoring intervention strategies to vulnerable sociodemographic profiles could optimize mental health benefits among those with hearing loss. Integrating hearing health services within mental healthcare delivery frameworks is vital amidst the rising global burden.

Introdução: A perda auditiva é uma deficiência comum na população mundial e contribui para dificuldade na comunicação verbal e redução da qualidade de vida, evidenciando a importância da identificação precoce, reabilitação e acompanhamento audiológico dessa deficiência para mitigar suas consequências. Durante a pandemia da COVID-19, as medidas restritivas diminuíram a capacidade de atendimento dos serviços de saúde auditiva e dificultaram a busca de auxílio para resolver problemas relacionados à adaptação aos dispositivos eletrônicos de amplificação sonora (DAES), sendo uma barreira no processo de reabilitação da perda auditiva. Objetivo: Caracterizar os usuários de DEAS e o processo inicial de reabilitação auditiva de adultos e idosos e verificar fatores associados ao retorno para a consulta de monitoramento auditivo durante o período inicial da pandemia da COVID-19.Métodos: Estudo observacional transversal com usuários adultos e idosos de um serviço ambulatorial de saúde auditiva com retorno para consulta de monitoramento auditivo agendada no período inicial da implementação das medidas restritivas da pandemia da COVID-19 no Brasil. Resultados: A maioria dos participantes conseguiu retornou para a consulta de monitoramento auditivo, sendo eles em sua maioria idosos, do sexo feminino e vacinados contra a COVID-19. Houve maior prevalência de adaptação adequada aos DAES. Não houve associação estatística entre as variáveis relacionadas à adaptação aos DAES, COVID-19 e saúde mental e o retorno à consulta de monitoramento auditivo. Conclusão: Os fatores relacionados à adaptação aos DAES, à COVID-19 ou à saúde mental não influenciaram o retorno à consulta de monitoramento auditivo na presente pesquisa. (AU)
Introduction: Hearing loss is a common disability in the world population and contributes to difficulty in verbal communication and reduced quality of life, highlighting the importance of early identification, rehabilitation and audiological monitoring of this disability to mitigate its consequences. During the COVID-19 pandemic, restrictive measures reduced the service capacity of hearing health services and made it difficult to seek help to solve problems related to adaptation to personal sound amplification products (PSAPs), being a barrier in the rehabilitation process of hearing loss. Aim: To characterize PSAPs users and the initial hearing rehabilitation process for adults and elderly people and verify the factors associated with the return to hearing monitoring consultations in the initial period of the COVID-19 pandemic. Methods: Cross-sectional observational study with adults and elderly people: elderly users of an outpatient hearing health service who return for a scheduled hearing monitoring consultation in the initial period of the implementation of restrictive measures of the COVID-19 pandemic in Brazil. Results: Most participants were able to return to the hearing monitoring clinic, the majority of whom were elderly, female and vaccinated against COVID-19. There was a higher prevalence of adequate adaptation to the PSAPs. There was no statistical association between variables related to adaptation to PSAPs, COVID-19 and mental health and return to hearing monitoring consultation. Conclusion: Factors related to adaptation to PSAPs, COVID-19 or mental health did not influence the return to hearing monitoring consultation in the present investigation. (AU)
