Hearing Rehabilitation With a Chat-Based Mobile Auditory Training Program in Experienced Hearing Aid Users: Prospective Randomized Controlled Study.

BACKGROUND: Hearing rehabilitation with auditory training (AT) is necessary to improve speech perception ability in patients with hearing loss. However, face-to-face AT has not been widely implemented due to its high cost and personnel requirements. Therefore, there is a need for the development of a patient-friendly, mobile-based AT program. OBJECTIVE: In this study, we evaluated the effectiveness of hearing rehabilitation with our chat-based mobile AT (CMAT) program for speech perception performance among experienced hearing aid (HA) users. METHODS: A total of 42 adult patients with hearing loss who had worn bilateral HAs for more than 3 months were enrolled and randomly allocated to the AT or control group. In the AT group, CMAT was performed for 30 minutes a day for 2 months, while no intervention was provided in the control group. During the study, 2 patients from the AT group and 1 patient from the control group dropped out. At 0-, 1- and 2-month visits, results of hearing tests and speech perception tests, compliance, and questionnaires were prospectively collected and compared in the 2 groups. RESULTS: The AT group (n=19) showed better improvement in word and sentence perception tests compared to the control group (n=20; P=.04 and P=.03, respectively), while no significant difference was observed in phoneme and consonant perception tests (both P>.05). All participants were able to use CMAT without any difficulties, and 85% (17/20) of the AT group completed required training sessions. There were no changes in time or completion rate between the first and the second month of AT. No significant difference was observed between the 2 groups in questionnaire surveys. CONCLUSIONS: After using the CMAT program, word and sentence perception performance was significantly improved in experienced HA users. In addition, CMAT showed high compliance and adherence over the 2-month study period. Further investigations are needed to validate long-term efficacy in a larger population.

Modeling the Intelligibility Benefit of Active Noise Cancelation in Hearing Devices That Improve Signal-to-Noise Ratio.

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 (>70 dB SPL) and devices are moderately capable of increasing SNR (by >4 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.

Impact of Hearing Aids on Language Outcomes in Preschool Children With Mild Bilateral Hearing Loss.

This study aimed to investigate the role of hearing aid (HA) usage in language outcomes among preschool children aged 3-5 years with mild bilateral hearing loss (MBHL). The data were retrieved from a total of 52 children with MBHL and 30 children with normal hearing (NH). The association between demographical, audiological factors and language outcomes was examined. Analyses of variance were conducted to compare the language abilities of HA users, non-HA users, and their NH peers. Furthermore, regression analyses were performed to identify significant predictors of language outcomes. Aided better ear pure-tone average (BEPTA) was significantly correlated with language comprehension scores. Among children with MBHL, those who used HA outperformed the ones who did not use HA across all linguistic domains. The language skills of children with MBHL were comparable to those of their peers with NH. The degree of improvement in audibility in terms of aided BEPTA was a significant predictor of language comprehension. It is noteworthy that 50% of the parents expressed reluctance regarding HA use for their children with MBHL. The findings highlight the positive impact of HA usage on language development in this population. Professionals may therefore consider HAs as a viable treatment option for children with MBHL, especially when there is a potential risk of language delay due to hearing loss. It was observed that 25% of the children with MBHL had late-onset hearing loss. Consequently, the implementation of preschool screening or a listening performance checklist is recommended to facilitate early detection.

Characterizing the relationship between modulation sensitivity and pitch resolution in cochlear implant users.

Cochlear implants are medical devices that have restored hearing to approximately one million people around the world. Outcomes are impressive and most recipients attain excellent speech comprehension in quiet without relying on lip-reading cues, but pitch resolution is poor compared to normal hearing. Amplitude modulation of electrical stimulation is a primary cue for pitch perception in cochlear implant users. The experiments described in this article focus on the relationship between sensitivity to amplitude modulations and pitch resolution based on changes in the frequency of amplitude modulations. In the first experiment, modulation sensitivity and pitch resolution were measured in adults with no known hearing loss and in cochlear implant users with sounds presented to and processed by their clinical devices. Stimuli were amplitude-modulated sinusoids and amplitude-modulated narrow-band noises. Modulation detection and modulation frequency discrimination were measured for modulation frequencies centered on 110, 220, and 440 Hz. Pitch resolution based on changes in modulation frequency was measured for modulation depths of 25 %, 50 %, 100 %, and for a half-waved rectified modulator. Results revealed a strong linear relationship between modulation sensitivity and pitch resolution for cochlear implant users and peers with no known hearing loss. In the second experiment, cochlear implant users took part in analogous procedures of modulation sensitivity and pitch resolution but bypassing clinical sound processing using single-electrode stimulation. Results indicated that modulation sensitivity and pitch resolution was better conveyed by single-electrode stimulation than by clinical processors. Results at 440 Hz were worse, but also not well conveyed by clinical sound processing, so it remains unclear whether the 300 Hz perceptual limit described in the literature is a technological or biological limitation. These results highlight modulation depth and sensitivity as critical factors for pitch resolution in cochlear implant users and characterize the relationship that should inform the design of modulation enhancement algorithms for cochlear implants.

An Exploration of the Memory Performance in Older Adult Hearing Aid Users on the Integrated Digit-in-Noise Test.

This study aimed to preliminarily investigate the associations between performance on the integrated Digit-in-Noise Test (iDIN) and performance on measures of general cognition and working memory (WM). The study recruited 81 older adult hearing aid users between 60 and 95 years of age with bilateral moderate to severe hearing loss. The Chinese version of the Montreal Cognitive Assessment Basic (MoCA-BC) was used to screen older adults for mild cognitive impairment. Speech reception thresholds (SRTs) were measured using 2- to 5-digit sequences of the Mandarin iDIN. The differences in SRT between five-digit and two-digit sequences (SRT5-2), and between five-digit and three-digit sequences (SRT5-3), were used as indicators of memory performance. The results were compared to those from the Digit Span Test and Corsi Blocks Tapping Test, which evaluate WM and attention capacity. SRT5-2 and SRT5-3 demonstrated significant correlations with the three cognitive function tests (rs ranging from -.705 to -.528). Furthermore, SRT5-2 and SRT5-3 were significantly higher in participants who failed the MoCA-BC screening compared to those who passed. The findings show associations between performance on the iDIN and performance on memory tests. However, further validation and exploration are needed to fully establish its effectiveness and efficacy.

On the Feasibility of Using Behavioral Listening Effort Test Methods to Evaluate Auditory Performance in Cochlear Implant Users.

Realistic outcome measures that reflect everyday hearing challenges are needed to assess hearing aid and cochlear implant (CI) fitting. Literature suggests that listening effort measures may be more sensitive to differences between hearing-device settings than established speech intelligibility measures when speech intelligibility is near maximum. Which method provides the most effective measurement of listening effort for this purpose is currently unclear. This study aimed to investigate the feasibility of two tests for measuring changes in listening effort in CI users due to signal-to-noise ratio (SNR) differences, as would arise from different hearing-device settings. By comparing the effect size of SNR differences on listening effort measures with test-retest differences, the study evaluated the suitability of these tests for clinical use. Nineteen CI users underwent two listening effort tests at two SNRs (+4 and +8 dB relative to individuals' 50% speech perception threshold). We employed dual-task paradigms-a sentence-final word identification and recall test (SWIRT) and a sentence verification test (SVT)-to assess listening effort at these two SNRs. Our results show a significant difference in listening effort between the SNRs for both test methods, although the effect size was comparable to the test-retest difference, and the sensitivity was not superior to speech intelligibility measures. Thus, the implementations of SVT and SWIRT used in this study are not suitable for clinical use to measure listening effort differences of this magnitude in individual CI users. However, they can be used in research involving CI users to analyze group data.

Two are better than one: Differences in cortical EEG patterns during auditory and visual verbal working memory processing between Unilateral and Bilateral Cochlear Implanted children.

Despite the proven effectiveness of cochlear implant (CI) in the hearing restoration of deaf or hard-of-hearing (DHH) children, to date, extreme variability in verbal working memory (VWM) abilities is observed in both unilateral and bilateral CI user children (CIs). Although clinical experience has long observed deficits in this fundamental executive function in CIs, the cause to date is still unknown. Here, we have set out to investigate differences in brain functioning regarding the impact of monaural and binaural listening in CIs compared with normal hearing (NH) peers during a three-level difficulty n-back task undertaken in two sensory modalities (auditory and visual). The objective of this pioneering study was to identify electroencephalographic (EEG) marker pattern differences in visual and auditory VWM performances in CIs compared to NH peers and possible differences between unilateral cochlear implant (UCI) and bilateral cochlear implant (BCI) users. The main results revealed differences in theta and gamma EEG bands. Compared with hearing controls and BCIs, UCIs showed hypoactivation of theta in the frontal area during the most complex condition of the auditory task and a correlation of the same activation with VWM performance. Hypoactivation in theta was also observed, again for UCIs, in the left hemisphere when compared to BCIs and in the gamma band in UCIs compared to both BCIs and NHs. For the latter two, a correlation was found between left hemispheric gamma oscillation and performance in the audio task. These findings, discussed in the light of recent research, suggest that unilateral CI is deficient in supporting auditory VWM in DHH. At the same time, bilateral CI would allow the DHH child to approach the VWM benchmark for NH children. The present study suggests the possible effectiveness of EEG in supporting, through a targeted approach, the diagnosis and rehabilitation of VWM in DHH children.

Focusing on Positive Listening Experiences Improves Speech Intelligibility in Experienced Hearing Aid Users.

Negativity bias is a cognitive bias that results in negative events being perceptually more salient than positive ones. For hearing care, this means that hearing aid benefits can potentially be overshadowed by adverse experiences. Research has shown that sustaining focus on positive experiences has the potential to mitigate negativity bias. The purpose of the current study was to investigate whether a positive focus (PF) intervention can improve speech-in-noise abilities for experienced hearing aid users. Thirty participants were randomly allocated to a control or PF group (N = 2 × 15). Prior to hearing aid fitting, all participants filled out the short form of the Speech, Spatial and Qualities of Hearing scale (SSQ12) based on their own hearing aids. At the first visit, they were fitted with study hearing aids, and speech-in-noise testing was performed. Both groups then wore the study hearing aids for two weeks and sent daily text messages reporting hours of hearing aid use to an experimenter. In addition, the PF group was instructed to focus on positive listening experiences and to also report them in the daily text messages. After the 2-week trial, all participants filled out the SSQ12 questionnaire based on the study hearing aids and completed the speech-in-noise testing again. Speech-in-noise performance and SSQ12 Qualities score were improved for the PF group but not for the control group. This finding indicates that the PF intervention can improve subjective and objective hearing aid benefits.

Viewpoint on the Benefit of Hearing Care on Cognitive Health.

PURPOSE: The purpose of this article is to provide a viewpoint on the recently published results showing the positive effect hearing intervention can have on mitigating the risk of cognitive decline in elderly individuals with hearing impairment. We intend to trigger a broader discussion on the implications of these results from an implementation science perspective. METHODS: Recently published results were reviewed and contextualized. RESULTS: In our view, these recent findings provide a great opportunity for hearing care professionals to change the perspective on hearing care being an essential service that contributes not only to managing challenges with audibility but to enabling healthy living and aging. CONCLUSION: As exciting as these findings are, from our perspective, they are also a call to action for the audiology field in terms of clinical implementation science. The findings guide us toward a more interprofessional approach in order to develop and test new, more holistic models of hearing care.

Provision of bone conduction hearing implants in England in adults and children: a review of Hospital Episode Statistics data 2012-2021.

OBJECTIVE: Bone conduction hearing implants are a well-established method of hearing rehabilitation in children and adults. This study aimed to review any changes in provision in England. METHODS: The total number of bone conduction hearing implantations performed was analysed from 2012 to 2021 utilising Hospital Episode Statistics data for England. RESULTS: The total number of procedures has increased by 58 per cent. One-stage bone conduction hearing implantations in adults accounts for the largest proportion of this increase (93 per cent of the total). The number performed in children has remained stable and accounts for 73 per cent (n = 433) of all two-stage procedures. CONCLUSION: The data show that bone conduction hearing implant surgery is becoming increasingly popular, particularly in adults. This has correlated with the increase in availability, national recommendations and choice of devices.

[Frankfurt concept of early inpatient rehabilitation after cochlear implant treatment : Feasibility for aftercare. German version]. / Frankfurter Konzept einer stationären Cochleaimplantat-Frührehabilitation : Untersuchung zur Durchführbarkeit als Anschlussheilbehandlung.

BACKGROUND: The Association of the Scientific Medical Societies in Germany (AWMF) clinical practice guideline on cochlear implant (CI) treatment, which was updated in 2020, defined the entire process of CI care for the first time. In the present study, the feasibility and results of very early rehabilitation were examined. MATERIALS AND METHODS: The intervention group (IG) comprised 54 patients in whom rehabilitation was initiated within 14 (maximally 28) days after implantation. Patients with a significantly longer waiting time were included in the control group (CG, n = 21). In addition to the start and duration of rehabilitation, the speech intelligibility achieved with CI was recorded at different timepoints within a 12-month period. In addition, questionnaires were used to assess the effort of fitting the CI processor and the patients' satisfaction with the outcome as well as the timing of the start of rehabilitation. RESULTS: Median waiting time between implantation and start of rehabilitation was 14 days in the IG and 106 days in the CG; 92.6% of IG patients were able to start rehabilitation within 14 days. The effect of rehabilitation in the IG was 35 and in the CG 25 percentage points (Freiburg monosyllabic test). After 6 and 12 months of CI use, both groups showed comparable results in the test condition in quiet (IG/CG 6 months: 70%/70%; 12 months: 70%/60%, Freiburg monosyllabic test) and in noise (IG/CG 6 months: -1.1-0.85 dB SNR; 12 months: -0.65 dB SNR/0.3 dB SNR, Oldenburg sentence test). Hearing quality assessment scores collected by SSQ (Speech, Spatial and Qualities of Hearing Scale) questionnaire showed better scores in the IG at 6 months, which converged to CG scores at 12 months. The IG was significantly more satisfied with the timing of the start of rehab than the CG. All other data obtained from questionnaires showed no differences between the two groups. CONCLUSION: A very early start of inpatient rehabilitation after cochlear implantation was successfully implemented. The rehabilitation was completed within 7 weeks of CI surgery. Comparison of speech recognition test results before and after rehabilitation showed a significant improvement. A clear rehabilitation effect can therefore be demonstrated. Inclusion of CI rehabilitation in the German catalog of follow-up treatments is thus scientifically justified and therefore strongly recommended.

Speech Perception Training in Children: The Retention of Benefits and Booster Training.

OBJECTIVES: Speech perception training can be a highly effective intervention to improve perception and language abilities in children who are deaf or hard of hearing. Most studies of speech perception training, however, only measure gains immediately following training. Only a minority of cases include a follow-up assessment after a period without training. A critical unanswered question was whether training-related benefits are retained for a period of time after training has stopped. A primary goal of this investigation was to determine whether children retained training-related benefits 4 to 6 weeks after they completed 16 hours of formal speech perception training. Training was comprised of either auditory or speechreading training, or a combination of both. Also important is to determine if "booster" training can help increase gains made during the initial intensive training period. Another goal of the study was to investigate the benefits of providing home-based booster training during the 4- to 6-week interval after the formal training ceased. The original investigation ( Tye-Murray et al. 2022 ) compared the effects of talker familiarity and the relative benefits of the different types of training. We predicted that the children who received no additional training would retain the gains after the completing the formal training. We also predicted that those children who completed the booster training would realize additional gains. DESIGN: Children, 6 to 12 years old, with hearing loss who had previously participated in the original randomized control study returned 4 to 6 weeks after the conclusion to take a follow-up speech perception assessment. The first group (n = 44) returned after receiving no formal intervention from the research team before the follow-up assessment. A second group of 40 children completed an additional 16 hours of speech perception training at home during a 4- to 6-week interval before the follow-up speech perception assessment. The home-based speech perception training was a continuation of the same training that was received in the laboratory formatted to work on a PC tablet with a portable speaker. The follow-up speech perception assessment included measures of listening and speechreading, with test items spoken by both familiar (trained) and unfamiliar (untrained) talkers. RESULTS: In the group that did not receive the booster training, follow-up testing showed retention for all gains that were obtained immediately following the laboratory-based training. The group that received booster training during the same interval also maintained the benefits from the formal training, with some indication of minor improvement. CONCLUSIONS: Clinically, the present findings are extremely encouraging; the group that did not receive home-based booster training retained the benefits obtained during the laboratory-based training regimen. Moreover, the results suggest that self-paced booster training maintained the relative training gains associated with talker familiarity and training type seen immediately following laboratory-based training. Future aural rehabilitation programs should include maintenance training at home to supplement the speech perception training conducted under more formal conditions at school or in the clinic.

Teledelivery of Aural Rehabilitation to Improve Cochlear Implant Outcomes.

OBJECTIVE(S): This randomized controlled study evaluated the effectiveness of a Telehealth Aural Rehabilitation (TeleAR) training protocol to improve outcomes for adult cochlear implant (CI) users. METHODS: This was a multisite clinical study with participants randomized to either an AR treatment or active control group. The AR protocol consisted of auditory training (words, sentences, and speech tracking), informational counseling, and communication strategies. The control group participants engaged in cognitive stimulation activities (crosswords, sudoku, etc.). Each group completed 6 weekly 90-min individual treatment sessions delivered remotely. Twenty postlingually deafened adult CI users participated. Assessments were completed pretreatment and 1 week and 2 months posttreatment. RESULTS: Repeated-measures ANOVA and planned contrasts were used to compare group performance on AzBio Sentences, Hearing Handicap Inventory (HHI), Client Oriented Scale of Improvement (COSI), and Glasgow Benefit Inventory (GBI). The two groups were statistically equivalent on all outcome measures at pre-assessment. There was a statistically significant main effect of time for all measures. Improvement over time was observed for participants in both groups, with greater improvement seen for the AR than the CT group on all outcome measures. The AR group showed medium to large effect sizes on all measures over time, suggesting clinically significant outcomes. CONCLUSION: This randomized controlled study provides evidence of improved speech recognition and psychosocial outcomes following 6 weeks of TeleAR intervention. For adult post-lingually deafened CI users, including those >3 months post-activation, AR treatment can leverage neuroplasticity to maximize outcomes.

Viva Melhor: Saúde Auditiva dos Adultos

No Brasil, quase dez milhões de brasileiros tem algum tipo de deficiência auditiva, o que representa pouco mais de cinco por cento da população brasileira, segundo o último censo do IBGE, divulgado em 2010. Desse total, cerca de seis milhões estão concentrados em áreas urbanas, como a capital paulista. Veja na reportagem como cuidar da audição.

Universo Infantil: Saúde auditiva dos bebês

A deficiência auditiva pode vir de nascença, mas também pode ser adquirida. Para identificar logo cedo se há algum problema na audição da criança, os cuidados já começam antes mesmo do bebê nascer. Acompanhe na reportagem.

Contribuição do potencial evocado auditivo de estado estável na escolha do implante coclear ou aparelho de amplificação sonora em crianças com perda auditiva / Contribution of auditory steady state evoked potential to the election of cochlear implantation or hearing aid for children with hearing impairment / Contribución del potencial evocado auditivo de estado estable en la elección de implantación coclear o audífono en niños con deficiencia auditiva

Introdução: A deficiência auditiva em crianças prejudica a aquisição e o desenvolvimento da linguagem oral, o que pode ser minimizado com o diagnóstico e a confirmação da surdez nos primeiros meses de vida. O Potencial Evocado auditivo de estado estável (PEAEE) destaca-se diante dos demais potenciais evocados auditivos devido à facilidade de registro, à objetividade das respostas, à estimulação de várias frequências simultaneamente, em ambas as orelhas, além da identificação da audição residual. Objetivo: Verificar a contribuição do PEAEE na definição terapêutica (escolha do implante coclear ou aparelho de amplificação sonora) para a reabilitação auditiva de crianças. Método: Foram analisados os registros de 20 crianças de um mês a três anos de idade com perda auditiva neurossensorial de grau severo ou profundo bilateral e que foram submetidas ao PEAEE e ao potencial evocado auditivo de tronco encefálico frequência específica (PEATE-FE). Ambos realizados nas frequências de 500 Hz e 2000 Hz no equipamento Smart-EP Intelligent Hearing Systems®. Resultados: Houve diferença entre os exames quanto à ocorrência de resíduo auditivo, pois, um número significativo de indivíduos apresentou respostas ausentes no PEATE-FE e respostas presentes no PEAEE. Não ocorreu associação entre a presença de resíduo auditivo, o grau da perda e a idade da criança com o tipo de intervenção terapêutica. Conclusão: A presença de resíduo auditivo, a classificação do grau da perda e a idade da criança não influenciaram na conduta terapêutica final. (AU)

Introduction: Hearing impairment in children debilitates the acquisition and development of oral language, which can be minimized with diagnosis and confirmation of deafness in the first months of life. Auditory Steady State Evoked Potential (ASSEP) analysis stands out from others auditory evoked potentials due to the ease of recording, objectivity of the answers, stimulation of several frequencies simultaneously, in both ears, besides the identification of residual hearing. Purpose: Determine the contribution of the ASSEP for the therapeutic definition (election of cochlear implantation or hearing aid device) in hearing rehabilitation of children. Methods: The records of 20 children aged one month to three years with severe or profound bilateral neurosensory hearing loss, who were submitted to ASSEP and specific frequency brainstem auditory evoked potential (BAEP) analysis were analyzed. Both tests performed at frequencies of 500 Hz and 2000 Hz using the equipment Smart-EP Intelligent Hearing Systems®. Results: There was difference between the exams regarding the occurrence of residual hearing, since a significant number of individuals had absent responses on the BAEP and present responses on the ASSEP. There was no association between the presence of residual hearing, degree of hearing loss and the child's age with the type of therapeutic intervention. Conclusion: The presence of residual hearing, classification of the degree of loss and child's age exerted no influence on the final conduct. (AU)

Efficacy of auditory verbal therapy in children with cochlear implantation based on auditory performance - A systematic review.

This systematic review focuses on the efficacy of auditory verbal therapy (AVT) in children with cochlear implants based on their auditory performance. The results presented are based on research findings from 2010 to 2021. The systematic review was designed based on the Popular Reporting Systems for the Systematic Review and Analysis of Meta-Analysts (PRISMA), the 2020 revised version, and the Critical Evidence for Clinical Evidence (CATE) checklist. Specific keywords were chosen based on the formulated research question and searched on the following search engines: Google Scholar, Microsoft Academic, PubMed, Semantic Scholar, Cochrane, Science Direct, and BASE. All the searched articles were analysed based on specific exclusion criteria. The results revealed an important progression based on the auditory performance among children with cochlear implantation who received habilitation. The studies highlight that younger the age at implantation better the auditory performance and this may be necessary to allow at least relatively normal organization of auditory pathways in pre-lingual children with hearing impairment. Therefore, regular revitalization of aural-verbal rehabilitation and speech and language therapy is essential for younger children with hearing impairment to achieve the highest level of hearing function. This systematic review highlights importance of assessment of the auditory performance to be considered in the test battery while evaluating children with CI before and after habilitation along with AVT.

American Speech-Language-Hearing Association Clinical Practice Guideline on Aural Rehabilitation for Adults With Hearing Loss.

BACKGROUND: Hearing loss poses a significant public health challenge as a common chronic condition with many known side effects that are often worse when left untreated. Aural rehabilitation (AR) is an umbrella term that encompasses a range of interventions (e.g., informational counseling and perceptual training) designed to reduce deficits related to hearing loss that may stand alone or be used in combination as part of a holistic plan. PURPOSE: This evidence-based clinical practice guideline is intended to inform the implementation of person-centered AR to adults with hearing loss. Given the well-known benefits of sensory management, it was not included within the scope of this guideline. The recommendations aim to help clinicians, individuals with hearing loss, and other stakeholders make evidence-informed treatment decisions and improve clinical outcomes, as well as provide payers and policymakers with information detailing a comprehensive approach to AR. METHOD: The American Speech-Language-Hearing Association (ASHA) and a multidisciplinary panel of subject matter experts prioritized key clinical questions and outcomes that served as the foundation of the guideline. The clinical recommendations were based on a comprehensive systematic review and a meta-analysis of 85 studies published between 1978 and 2021. RECOMMENDATIONS: Given the current state of the evidence, resource considerations, patient acceptability, clinical feasibility, and the overall balance of benefits and harms, ASHA developed several evidence-based recommendations for the provision of AR to adults with hearing loss. Each recommendation is accompanied by a series of key practice points to support its implementation within a person-centered framework.

Factors associated with change in the need for recovery and subjective listening effort in employees with hearing loss receiving aural rehabilitation.

OBJECTIVE: Compared to normally-hearing employees, those with hearing loss suffer from higher Need For Recovery (NFR) after work. The aims of this study are to assess the NFR of employees with hearing loss before and after aural rehabilitation and to examine to what extent change in the NFR can be explained by changes in subjective listening effort, personal adjustments, communication strategies, auditory work demands, and self-reported hearing ability. METHODS: We included patients who received aural rehabilitation in two audiological centers in the Netherlands because of hearing complaints in their work situation. Outcomes were measured by questionnaires at baseline and 3 month follow-up. The NFR before and after the rehabilitation was compared with a t test. Hierarchical multiple analyses were performed. RESULTS: In total, 60 patients (aged 22-63, working hours ≥8 per week) participated in the study, of which 50 completed the follow-up questionnaires. The NFR was significantly lower after the aural rehabilitation (M = 45.03) compared to before the aural rehabilitation (M = 51.89), t = -3.43, p < 0.01). Change in NFR could best be explained by the change in personal adjustments (R2 = 0.45, B = -1.23, p < 0.01). CONCLUSION: The NFR of employees with hearing loss can be improved by aural rehabilitation, but this study shows that current practices reduce the NFR only in part of the employees. Therefore, improving current practices should be considered and evaluated, for example by applying a different combination of rehabilitation components. Especially, interventions that affect personal adjustments may be promising to further reduce the NFR in employees with hearing loss.

Phonological Awareness and Working Memory in Mandarin-Speaking Preschool-Aged Children With Cochlear Implants.

PURPOSE: Cochlear implants (CIs) provide significant benefits for profoundly deaf children in their language and cognitive development. However, it remains unclear whether Mandarin-speaking young children with early implantation can develop age-equivalent phonological awareness (PA) skill and working memory (WM) capacity as their normal hearing (NH) peers. The aim of this study was to investigate PA and WM in preschool-aged children with or without hearing loss and to examine the relationship between the two basic skills. METHOD: The data were collected from 16 Mandarin-speaking preschoolers with CIs and 16 age-matched children with NH. All preschool participants were instructed to complete four phonological detection tasks and four digit span tasks. Linear mixed-effects modeling was performed to evaluate PA and WM performances between two groups across different tasks. RESULTS: CI preschoolers showed comparable performances on par with NH controls in phonological detections and visual digit spans. In addition, Pearson correlation analysis revealed a positive relationship between phonological detections and auditory digit spans in preschool-aged children with CIs. CONCLUSION: With early implantation, the congenitally deaf children were capable of developing age-appropriate PA skill and WM capacity, which have practical implications for aural rehabilitation in this special pediatric population.
