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.

An Analysis of Mental State Verb and Complex Syntax Use in Children Who Are Deaf and Hard of Hearing.

PURPOSE: Children who are deaf and hard of hearing (DHH) have documented deficits with complex syntax and vocabulary knowledge. Mental state verbs (MSVs) are necessary for some kinds of complex syntax use and communicate abstract concepts needed for academic language. The purpose of this study was to examine the frequency, diversity, and syntactic context of MSV use in children who are DHH compared to children with typical hearing (CTH). METHOD: Seventy-three preschool children (23 with cochlear implants, 22 with hearing aids, and 28 with typical hearing) completed a structured language sample as part of a larger assessment battery. Samples were analyzed and compared across groups for use of MSVs, diversity in MSV use, and syntactical context for MSVs. RESULTS: Children who are DHH used significantly fewer MSV in complex syntax, a smaller diversity of MSV, and significantly fewer MSV in obligatory contexts compared to CTH. Results for the cochlear implants and hearing aid groups were not significantly different from one another despite differing levels of hearing loss. CONCLUSION: Children who are DHH demonstrate significant differences in the rate, diversity, and complexity of MSV use compared to peers with typical hearing.

[Improving Social Participation through Cochlear Implants for Hearing Impaired Persons? On the Ambivalence of Human-Machine-Interaction and the Importance of Psycho-Social Support]. / Mehr soziale Teilhabe für Hörgeschädigte durch Cochlea-Implantate? Zur Ambivalenz der Mensch-Maschine-Interaktion und zum Stellenwert psycho-sozialer Begleitung.

AIM OF THE STUDY: Cochlea implants help persons that suffer from deafness over time to regain hearing capacity. However, persons with CI implants experience year-long processes of adapting to technology-assisted hearing. The study highlights how people experience those processes and how they deal with changing expectations. METHODS: Within this qualitative study, 50 cochlear implant recipients were interviewed about their personal experiences with the supplying clinics. 30 persons were recruited through self-help groups; another 20 persons were recruited through a learning center for hearing-impaired persons. They were asked about their experiences in social, cultural and professional participation as well as hearing barriers they still face in everyday life after their CI fitting. Participants had been wearing CI devices for a maximum of three years. This is a timeframe when most subsequent therapies have ended. Also, the initial phase of learning to handle the CI is supposed to be over. RESULTS: The study shows that even with a cochlear implant communication barriers remain. People's expectations are not met when complete comprehension of listening during conversations is not achieved. Difficulties in dealing with a high-tech hearing prosthesis and experiencing a "foreign body" are obstacles that lower acceptance of CI. CONCLUSION: Counselling and support preparing the use of cochlea implants should be guided by realistic goals and expectations. Guided training and communication courses can help, including local care such as certified hearing aid acousticians. Those elements can increase quality and reduce uncertainty.

Saúde auditiva nas Coordenadorias Regionais de Saúde do estado do Rio Grande do Sul: regulação de acesso, desafios e perspectivas / Hearing health care in the Regional Health Coordinating Bodies in Rio Grande do Sul: access regulation, challenges, and perspectives

RESUMO Objetivo compreender a dinâmica da regulação de acesso, os desafios e as perspectivas da atuação das Coordenadorias Regionais de Saúde do Rio Grande do Sul (CRS/RS) em saúde auditiva. Métodos estudo exploratório, transversal, de natureza censitária e análise descritiva. Envolveu os responsáveis pela regulação dos procedimentos de saúde auditiva nas CRS/RS, entrevistados quanto à formação profissional, identificação dos procedimentos disponíveis e respectiva oferta, sistemática da regulação de acesso e outras ações em saúde auditiva. Resultados participaram 15 profissionais, todas mulheres, de 16 das 18 CRS/RS existentes, entre 30 e 47 anos de idade: 13 fonoaudiólogas e duas fisioterapeutas, graduadas entre 1997 e 2012; 13 possuíam pós-graduação. Sobre a regulação nas CRS/RS, 13 utilizavam o Sistema Nacional de Regulação e três a realizavam manualmente; 12 utilizavam o protocolo disponibilizado pela Secretaria Estadual de Saúde/RS; dez CRS/RS regulavam procedimentos de Triagem Auditiva Neonatal e 16, de avaliação e diagnóstico, bem como de reabilitação. Verificou-se demanda reprimida para todos os procedimentos (maior para reabilitação auditiva) em 12 CRS/RS. Todas as CRS/RS realizavam uma ou mais ações promotoras da saúde auditiva, como vigilância, apoio matricial e atividades de educação em saúde. Conclusão a regulação de acesso em saúde auditiva é realizada de forma qualificada na maioria das CRS/RS. A oferta de procedimentos é insuficiente, sobretudo em reabilitação auditiva, que implica exclusiva atuação fonoaudiológica por meio de tecnologias leves e leve-duras.

ABSTRACT Purpose To understand the dynamics of access regulation, the challenges, and perspectives of the performance of the Regional Health Coordinating Bodies of Rio Grande do Sul (RHCB/RS) in hearing health care. Methods This is an exploratory, cross-sectional, census study and the analysis is descriptive. It involved those responsible for the regulation of hearing health care procedures in RHCB/RS, interviewed about professional training, identification of available procedures and their respective offer, access regulation systematics, and other actions in hearing health care. Results 15 professionals participated, all were women, from 16 of the 18 existing RHCB/RS, aged between 30 and 47; 13 speech-language pathologists and audiologists and two physiotherapists, who graduated between 1997 and 2012; and 13 had post -graduate degrees. Regarding regulation in RHCB/RS, 13 used the National Regulation System and three performed it manually; 12 used the protocol provided by the State Health Department/RS; ten RHCB/RS regulated procedures for Neonatal Hearing Screening and 16 for assessment and diagnosis, as well as auditory rehabilitation. There is a repressed demand for all procedures (greater for auditory rehabilitation) in 12 RHCB/RS. All RHCB/RS performed one or more actions to promote hearing health care such as surveillance, matrix support, and health education. Conclusion The access regulation in hearing health care is performed in a qualified way in most RHCB/RS; the offer of procedures is insufficient, especially in auditory rehabilitation, which includes exclusive speech-language pathologists and audiologists' performance through soft and soft-hard technologies.

Correspondência entre alvo e saída da prótese auditiva segundo as regras prescritivas NAL-NL1 e NAL-NL2 / Correspondência entre alvo e saída da prótese auditiva segundo as regras prescritivas NAL-NL1 e NAL-NL2

RESUMO Objetivo Analisar comparativamente os alvos prescritos pelas regras NAL (National Acoustic Laboratories) não lineares com a resposta da prótese auditiva obtida por meio das mensurações com microfone-sonda no ajuste de uso efetivo, de acordo com o grau da perda auditiva. Método Participaram do estudo 67 usuários experientes de próteses auditivas. Todos foram reavaliados quando compareceram às sessões de acompanhamento periódico. Nesse momento, realizou-se avaliação audiológica, registrando-se as horas de uso do dispositivo e realizando-se a resposta com prótese auditiva (REAR - Real Ear Aided Response). Resultados Observou-se que 80% das próteses auditivas de todos os grupos atingiram a faixa analisada, com exceção do grupo de perda moderada. Também foi realizada a análise da porcentagem de orelhas cuja resposta com prótese auditiva estivesse em ±5 dB para as frequências baixas e ±8 dB nas altas frequências e observou-se que menos de 80% dos ajustes atingiram esta faixa. Intervalos de confiança foram construídos para verificar a faixa de adaptação de preferência dos usuários experientes. Conclusão A faixa de ±10 dB demonstra ser a de preferência dos usuários. Porém, para usuários experientes, sugere-se que a faixa de adaptação encontre-se na faixa de ±3 nas frequências baixas e médias e ±7 na região de altas frequências.

ABSTRACT Purpose To compare the targets prescribed by the non-linear NAL with the real ear aided response - REAR obtained through probe microphone in the setting of effective use according to the degree of hearing loss. Methods 67 experienced hearing aid users participated in the study. All were reassessed when attending follow-up sessions. At that moment, they were asked whether they had any complaints with respect to the amplification. An audiological evaluation was performed, the hours of use of the device were recorded and the new probe microphone measurement was taken. Results The percentage of ears with REAR within ± 10dB of the prescriptive target was verified. It was observed that 80% of the hearing aids of all groups reached the analyzed range, with the exception of the moderate hearing loss group. We also performed the analysis of the percentage of ears whose hearing aid response was within ± 5 dB for the low frequencies and ± 8 dB for the high frequencies, and it was observed that less than 80% of the adjustments reached this range. Confidence intervals were constructed to verify the preference fit to target of experienced users. Conclusion The range of ±10dB proves to be the users' preference. For experienced users, it is suggested that the adaptation phase be found in the range of ±3 in the low and medium frequencies and ±7 in the high frequency region

Deaf Residents With Intellectual Disabilities During the First Covid-19 Associated Lockdown.

Two indicators for stress (mood and aggressive behavior) were evaluated in order to investigate the effect of the restrictions taken against the spread of the coronavirus on people who are deaf and hard of hearing (DHH) and have intellectual disabilities (ID). In three therapeutic living communities, specifically designed for the visual communication needs of people who are DHH and have ID, the mood of the residents is routinely assessed by staff members and every aggressive incident is recorded with the Staff Observation of Aggressions Scale-Revised (SOAS-R). For the 38 residents who were present 8 weeks before the first lockdown (t1) and the following 8 weeks (t2), mood ratings and ratings of aggressive behavior were compared between the two time periods. In contrast to our hypothesis the mood ratings of the residents had a slight significant improvement, whereas the incidents and severity of aggressive behavior did not change significantly. These results suggest that with proper communicative support, individuals who are DHH and have ID can cope effectively with significant restrictions imposed by a pandemic-caused lockdown.

Association of Age-Related Hearing Impairment With Physical Functioning Among Community-Dwelling Older Adults in the US.

Importance: Hearing impairment, a common treatable condition, may contribute to poorer physical function with aging. Objective: To assess whether hearing impairment is associated with poorer physical function, reduced walking endurance, and faster decline in physical function. Design, Setting, and Participants: In this cohort study, cross-sectional and longitudinal analyses were performed using data from the 2011 to 2019 period of the Atherosclerosis Risk in Communities study, a population-based study of community-dwelling adults at 4 sites in the US. Exposures: Hearing thresholds (per 10 dB) assessed with pure tone audiometry and categorized as normal hearing or mild, moderate, or severe hearing impairment. Main Outcomes and Measures: Physical function was assessed using the short physical performance battery (SPPB), with composite scores ranging from 0 to 12. A composite score of 6 or less and a score for each component (balance, gait speed, and chair stands) of 2 or less indicated poor performance. Walking endurance was assessed using a 2-minute fast-paced walk test. Tobit regression models adjusted for sociodemographic factors and medical history were used to calculate the mean differences in SPPB composite scores; logistic regression models, to estimate the odds ratios (ORs) of low SPPB composite and component scores; and linear mixed-effects models, to estimate the mean rate of change in SPPB composite scores over time. Results: Of the 2956 participants (mean [SD] age, 79 [4.6] years) who attended study visit 6 between 2016 and 2017, 1722 (58.3%) were women, and 2356 (79.7%) were White. As determined by pure tone audiometry, 973 (33%) participants had normal hearing, 1170 (40%) had mild hearing impairment, 692 (23%) had moderate hearing impairment, and 121 (4%) had severe hearing impairment. In the Tobit regression model, severe hearing impairment was associated with a lower mean SPPB score (ß, -0.82; 95% CI, -0.34 to -1.30) compared with normal hearing. In fully adjusted logistic regression models, hearing impairment was associated with higher odds of low physical performance scores (severe impairment vs normal hearing: OR for composite physical performance, 2.51 [95% CI, 1.47-4.27]; OR for balance, 2.58 [95% CI, 1.62-4.12]; OR for gait speed, 2.11 [95% CI, 1.03-4.33]). Over time (2 to 3 visits; maximum, 8.9 years), participants with hearing impairment had faster declines in SPPB compared with those with normal hearing (moderate hearing impairment × time interaction, -0.34 [-0.52 to -0.16]). In adjusted models for walking endurance, participants with moderate or severe hearing impairment walked a mean distance of -2.81 m (95% CI, -5.45 to -0.17 m) and -5.31 m (95% CI, -10.20 to -0.36 m) than those with normal hearing, respectively, during the 2-minute walk test. Conclusions and Relevance: In this cohort study, hearing impairment was associated with poorer performance, faster decline in physical function, and reduced walking endurance. The results of the longitudinal analysis suggest that hearing impairment may be associated with poorer physical function with aging. Whether management of hearing impairment could delay decline in physical function requires further investigation.

A Technology-Assisted Language Intervention for Children Who Are Deaf or Hard of Hearing: A Randomized Clinical Trial.

BACKGROUND AND OBJECTIVES: Children who are deaf or hard of hearing (DHH) often have persistent language delays despite early identification and interventions. The technology-assisted language intervention (TALI), which incorporates augmentative and alternative communication technology into a speech-language therapy model, was designed to support language learning. The study objective was to evaluate the impact of the TALI on spoken language outcomes in DHH children. METHODS: Children aged 3 to 12 years with mild to profound bilateral hearing loss were enrolled in a single-site randomized controlled trial. Children were randomly assigned to receive the TALI or treatment as usual (TAU) (with no change in current care) and were followed for 24 weeks. Primary outcomes included spoken language measures elicited from language samples. Secondary outcomes included standardized assessments. Intention-to-treat analyses were used. RESULTS: Analyses focused on 41 children randomly assigned to TALI (n = 21) or TAU (n = 20). Among all participants, mean age was 6.3 years (SD 2.5). Over 24 weeks, children in the TALI group, compared with those in the TAU group, had significantly greater increases in the length of phrases they used to express themselves (ß = .91 vs .15, respectively; P< .0001). Similar findings were seen with conversational turn-taking and number of different words spoken. CONCLUSIONS: Providing visual supports for language concepts that are typically challenging for DHH children to acquire allowed children to process and comprehend spoken language more fully. Such strategies can mitigate persistent language delays with the goal of improving lifelong outcomes and independence across settings.

An Integrative Review of Current Practice Models and/or Process of Family-Centered Early Intervention for Children Who Are Deaf or Hard of Hearing.

Over the past few decades, there has been an increasing shift toward emphasizing the importance of the child's family taking an active role in the habilitation process through family-centered early intervention (FCEI) programs. Accordingly, the Health Professions Council of South Africa recommends that early intervention services following confirmation of hearing loss must be family-centered within a community-based model of service delivery that is culturally congruent. The aim of this study was to explore and document current evidence reflecting trends in FCEI for children who are deaf or hard of hearing (DHH) by identifying and describing current practice models and/or processes of FCEI for these children. This study describes our first steps in formulating a framework for FCEI for children who are DHH in South Africa. An integrative literature review was conducted. Sage, Science Direct, PubMed, and Google Scholar databases were searched for studies published in English between January 2009 and January 2019 reporting on FCEI programs for children who are DHH. Studies that focused on the following were excluded from the study: speech and language outcomes of children, youth, and adults who are DHH; education for children who are DHH; universal newborn hearing screening; professionals' roles in early hearing detection and intervention; diagnosis of hearing loss; and sign language. Kappa statistics were performed to determine agreement between reviewers. Twenty-two studies were included in the review. Cohen's kappa revealed a substantial agreement (κ = 0.8) between reviewers for data extraction and synthesis in terms of the articles that met the criteria for inclusion in the review. Findings were discussed under 5 themes: caregiver involvement; caregiver coaching/information sharing; caregiver satisfaction; challenges with FCEI; and telehealth. Generally, there is sufficient evidence for FCEI, with caregivers indicating the need for full involvement in their children's care. Methods of caregiver involvement involving caregiver coaching/information sharing need to be culturally and linguistically appropriate, with sensitivities around time and manner. This increases caregiver satisfaction with intervention programs and improves outcomes for children who are DHH. Challenges identified by the studies raise implications for early hearing detection and intervention programs, as well as Departments of Health and Social Welfare. These included logistical challenges, professional-related challenges, and caregiver-related challenges. Various aspects of FCEI have been reported in the review. Findings of these studies have significant implications for the formulation of quality FCEI programs to ensure contextually relevant and contextually responsive care of children who are DHH.

Using haptic stimulation to enhance auditory perception in hearing-impaired listeners.

INTRODUCTION: Hearing-assistive devices, such as hearing aids and cochlear implants, transform the lives of hearing-impaired people. However, users often struggle to locate and segregate sounds. This leads to impaired threat detection and an inability to understand speech in noisy environments. Recent evidence suggests that segregation and localization can be improved by providing missing sound-information through haptic stimulation. AREAS COVERED: This article reviews the evidence that haptic stimulation can effectively provide sound information. It then discusses the research and development required for this approach to be implemented in a clinically viable device. This includes discussion of what sound information should be provided and how that information can be extracted and delivered. EXPERT OPINION: Although this research area has only recently emerged, it builds on a significant body of work showing that sound information can be effectively transferred through haptic stimulation. Current evidence suggests that haptic stimulation is highly effective at providing missing sound-information to cochlear implant users. However, a great deal of work remains to implement this approach in an effective wearable device. If successful, such a device could offer an inexpensive, noninvasive means of improving educational, work, and social experiences for hearing-impaired individuals, including those without access to hearing-assistive devices.

Expanding Stroke Preparedness to Vulnerable Populations: A Music Video for the Deaf Community.

Background Acute stroke treatments reduce disability after stroke, but eligibility for these treatments depends on rapid hospital arrival after symptom onset. Stroke preparedness interventions teach stroke symptoms and the importance of calling 911, thereby increasing patient eligibility for stroke treatments. Stroke preparedness interventions for the Deaf community are lacking. We sought to adapt a stroke preparedness music video, which was initially created for the hearing, for the Deaf community. Methods and Results We used a community-engaged approach, partnering with members of the Deaf community, to adapt the video over 4 months. Adaptation involved assessing the comprehensibility and appropriateness of the video and interpreting the song lyrics into American Sign Language. Conclusions We collaborated with the Deaf community to create a stroke preparedness video for the Deaf. Future research will involve refining the video and testing its efficacy to increase stroke symptom recognition and intent to call 911.

Electrophysiological assessment of temporal envelope processing in cochlear implant users.

Cochlear-implant (CI) users rely on temporal envelope modulations (TEMs) to understand speech, and clinical outcomes depend on the accuracy with which these TEMs are encoded by the electrically-stimulated neural ensembles. Non-invasive EEG measures of this encoding could help clinicians identify and disable electrodes that evoke poor neural responses so as to improve CI outcomes. However, recording EEG during CI stimulation reveals huge stimulation artifacts that are up to orders of magnitude larger than the neural response. Here we used a custom-built EEG system having an exceptionally high sample rate to accurately measure the artefact, which we then removed using linear interpolation so as to reveal the neural response during continuous electrical stimulation. In ten adult CI users, we measured the 40-Hz electrically evoked auditory steady-state response (eASSR) and electrically evoked auditory change complex (eACC) to amplitude-modulated 900-pulses-per-second pulse trains, stimulated in monopolar mode (i.e. the clinical default), and at different modulation depths. We successfully measured artifact-free 40-Hz eASSRs and eACCs. Moreover, we found that the 40-Hz eASSR, in contrast to the eACC, showed substantial responses even at shallow modulation depths. We argue that the 40-Hz eASSR is a clinically feasible objective measure to assess TEM encoding in CI users.

Early Intervention Protocols: Proposing a Default Bimodal Bilingual Approach for Deaf Children.

Despite advances in hearing technology, a growing body of research, as well as early intervention protocols, deaf children largely fail to meet age-based language milestones. This gap in language acquisition points to the inconsistencies that exist between research and practice. Current research suggests that bimodal bilingual early interventions at deaf identification provide children language foundations that can lead to more effective outcomes. Recommendations that support implementing bimodal bilingualism at deaf identification include early intervention protocols, language foundations, and the development of appropriate bimodal bilingual environments. All recommendations serve as multifaceted tools in a deaf child's repertoire as language and modality preferences develop and solidify. This versatile approach allows for children to determine their own language and communication preferences.

The impact of temporal fine structure and signal envelope on auditory motion perception.

The majority of psychoacoustic research investigating sound localization has utilized stationary sources, yet most naturally occurring sounds are in motion, either because the sound source itself moves, or the listener does. In normal hearing (NH) listeners, previous research showed the extent to which sound duration and velocity impact the ability of listeners to detect sound movement. By contrast, little is known about how listeners with hearing impairments perceive moving sounds; the only study to date comparing the performance of NH and bilateral cochlear implant (BiCI) listeners has demonstrated significantly poorer performance on motion detection tasks in BiCI listeners. Cochlear implants, auditory protheses offered to profoundly deaf individuals for access to spoken language, retain the signal envelope (ENV), while discarding temporal fine structure (TFS) of the original acoustic input. As a result, BiCI users do not have access to low-frequency TFS cues, which have previously been shown to be crucial for sound localization in NH listeners. Instead, BiCI listeners seem to rely on ENV cues for sound localization, especially level cues. Given that NH and BiCI listeners differentially utilize ENV and TFS information, the present study aimed to investigate the usefulness of these cues for auditory motion perception. We created acoustic chimaera stimuli, which allowed us to test the relative contributions of ENV and TFS to auditory motion perception. Stimuli were either moving or stationary, presented to NH listeners in free field. The task was to track the perceived sound location. We found that removing low-frequency TFS reduces sensitivity to sound motion, and fluctuating speech envelopes strongly biased the judgment of sounds to be stationary. Our findings yield a possible explanation as to why BiCI users struggle to identify sound motion, and provide a first account of cues important to the functional aspect of auditory motion perception.

American Sign Language Interpreters in Public Schools: An Illusion of Inclusion that Perpetuates Language Deprivation.

PURPOSE: Many deaf children have limited access to language, spoken or signed, during early childhood - which has damaging effects on many aspects of development. There has been a recent shift to consider deafness and language deprivation as separate but related conditions. As such, educational plans should differentiate between services related to deafness and services related to language deprivation. DESCRIPTION: Many deaf children attend mainstream public schools, and the primary service offered to students who use American Sign Language (ASL) is generally a sign language interpreter. ASSESSMENT: We argue that while sign language interpreters can be an effective accommodation for deafness (i.e., students who are deaf and not language-deprived), there is no reason to believe they are an effective accommodation for language deprivation (i.e., students who are deaf and language-deprived). CONCLUSION: Using interpreters instead of appropriate educational supports may exacerbate symptoms of language deprivation by prolonging the period of time a child goes with limited access to language.

How Bilingualism Contributes to Healthy Development in Deaf Children: A Public Health Perspective.

The aim of this article is to increase awareness of language practices in the deaf community that affect communication needs and health outcomes, focusing particularly on the prevalence of bilingualism among deaf adults. Language deprivation and poor health outcomes in the deaf population are risks that cannot be addressed solely by hearing intervention. We propose that bilingualism acts as a protective measure to minimize the health risks faced by deaf individuals. Provision of culturally and linguistically appropriate services to deaf stakeholders, and particularly hearing families of deaf children, requires familiarity with the developmental and social ramifications of bilingualism.

Electro-haptic stimulation enhances speech recognition in spatially separated noise for cochlear implant users.

Hundreds of thousands of profoundly hearing-impaired people perceive sounds through electrical stimulation of the auditory nerve using a cochlear implant (CI). However, CI users are often poor at understanding speech in noisy environments and separating sounds that come from different locations. We provided missing speech and spatial hearing cues through haptic stimulation to augment the electrical CI signal. After just 30 min of training, we found this "electro-haptic" stimulation substantially improved speech recognition in multi-talker noise when the speech and noise came from different locations. Our haptic stimulus was delivered to the wrists at an intensity that can be produced by a compact, low-cost, wearable device. These findings represent a significant step towards the production of a non-invasive neuroprosthetic that can improve CI users' ability to understand speech in realistic noisy environments.
