RESUMO

Internet of things (IoT) in healthcare, has effi-ciently accelerated medical monitoring and assessment through the real-time analysis of collected data. Hence, to support the hearing-impaired community with better calibrations to their clinical processors and hearing aids, a portable smart space interface - AURIS has been developed by the Cochlear Implant Processing Lab (CILab) at UT-Dallas. The proposed Auris interface periodically samples the acoustic space, and through a learn vs test phase, builds a Gaussian mixture model for each specific environmental locations. An effective connection is established by the Auris interface with the CRSS CCi-Mobile research platform through an android app to fine tune the con-figuration settings for cochlear implant (CI) or hearing aid (HA) users entering the room/location. Baseline objective evaluations have been performed in diverse naturalistic locations using 12 hours of audio data. The performance metrics is determined by a verified wireless communication, along with estimated acoustic environment knowledge and room classification at greater than 90% accuracy.

RESUMO

Existing computational studies of cochlear implants have demonstrated that the structural detail of threedimensional (3D) cochlear models exerts influence on the current spread within the cochlea. Nevertheless, the significance of including the microstructures inside the modiolar bone in a cochlear model is still unclear in the literature. We employed two different multi-compartment neuron models to simulate auditory nerve fibres, and compared response characteristics of the fibre population between a detailed and a simplified 3D cochlear model. Results showed that although the prediction of firing is dependent on the details of the neuron model, the responses of the fibre population to the electrical stimulus, especially the location of the initiation of action potential, varied between the detailed and the simplified models. Therefore, the inclusion of the modiolar microstructures in a cochlear model may be necessary for fully understanding the firing of auditory nerve fibres.

RESUMO

Auditory stream segregation is an important function of the auditory system, and the extent to which this function works has a major impact on listener's ability to recognize auditory objects in complex listening environments. However, cochlear implant (CI) listeners are poorly equipped for this challenge, mainly owing to the impoverished sensory information available via their implants. The purpose of this study was to examine two factors, i.e., frequency separation and time interval, affecting the auditory stream segregation in vocoder simulations simulating CI speech processing based on an event-related potential (ERP) experiment. The pure-tone stimuli were processed by a vocoding process, and presented to normal-hearing listeners in an ERP experiment. Experimental results showed that a large frequency separation or a short time interval led to a larger mismatch negativity (MMN) response. The MMN results in this work suggested that the degree of auditory stream segregation was affected by frequency separation and time interval, and MMN could serve as a potential index for future ERP studies on auditory stream segregation in CI users.

RESUMO

INTRODUCTION: Hearing rehabilitation with cochlear implants has attracted increasing interest also for patients with cochleovestibular schwannoma. The authors report their experience with the surgical management of tumors with rare transmodiolar or transmacular extension and outcomes after cochlear implantation (CI). METHODS: This retrospective case series included nine patients with either primary intralabyrinthine tumors or secondary invasion of the inner ear from the internal auditory canal. The primary endpoint with CI, performed in six patients, was word recognition score at 65 dB SPL (sound pressure level). Secondary endpoints were intra- and postoperative electrophysiological parameters, impedance measures, the presence of a wave V in the electrically evoked (via the CI) auditory brainstem responses, the specifics of postoperative CI programming, and adverse events. RESULTS: Hearing rehabilitation with CI in cases of transmodiolar tumor growth could be achieved only with incomplete tumor removal, whereas tumors with transmacular growth could be completely removed. All six patients with CI had good word recognition scores for numbers in quiet conditions (80-100% at 65 dB SPL, not later than 6 to 12 months post CI activation). Four of these six patients achieved good to very good results for monosyllabic words within 1-36 months (65-85% at 65 dB SPL). The two other patients, however, had low scores for monosyllables at 6 months (25 and 15% at 65 dB SPL, respectively) with worsening of results thereafter. CONCLUSIONS: Cochleovestibular schwannomas with transmodiolar and transmacular extension represent a rare entity with specific management requirements. Hearing rehabilitation with CI is a principal option in these patients.

RESUMO

Este estudio compara las estrategias para leer oraciones utilizadas por un grupo de escolares con dislexia (n = 107) y un grupo con sordera e implante coclear (n = 61) de lengua castellana. Los resultados indican que solo los participantes con sordera adoptan la estrategia de palabras clave (EPC), que consiste en identificar algunas de las palabras de la oración con contenido semántico propio, e ignorar las palabras funcionales. Se observa además que el uso de la EPC está asociado con un déficit sintáctico. Por otra parte, cuando los dos grupos se emparejan en el nivel lector con niños con desarrollo típico en lectura (Grupo Control, n = 785), las diferencias entre los Grupos Disléxico y Control desaparecieron. Sin embargo, los niños con sordera mantenían su tendencia a usar la EPC y seguían presentando dificultades para procesar las palabras funcionales. Estos resultados excluyen la hipótesis de que la EPC sea un procedimiento utilizado de forma general para compensar los déficits de lectura, pareciendo depender, más específicamente, de dificultades en la capacidad sintáctica


The present study compares the strategies to read sentences used by Spanish-speaking children with dyslexia (n = 107) and cochlear-implanted children with deafness (n = 61). The results show that children with deafness, but not with dyslexia, adopt the key-word-strategy (KWS), which consists of identifying some content words of the sentence while ignoring the function words. Furthermore, it appeared that the KWS was associated with poor syntactic ability. Moreover, when Dyslexic and Deaf Groups were carefully matched at reading level with normally developing children (Control Group, n = 785) all of the differences between dyslexics and normally developing children disappeared. Children with hearing loss however were still poor at dealing with function words and consequently maintained their tendency to use the KWS. These results exclude the hypothesis that the KWS is a broadly used procedure to compensate for reading deficits but seems, rather, to depend on poor syntactic ability

RESUMO

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.

RESUMO

Spectral ripple discrimination (SRD) has been widely used to evaluate the spectral resolution in cochlear implant (CI) recipients based on its strong correlation with speech perception performance. However, despite its usefulness for predicting speech perception outcomes, SRD performance exhibits large across-subject variabilities even among subjects implanted with the same CIs and sound processors. The potential factors of this observation include current spread, nerve survival, and CI mapping. Previous studies have found that the spectral resolution reduces with increasing distance of the stimulation electrode from the auditory nerve fibers (ANFs), attributable to increasing current spread. However, it remains unclear whether the spread of excitation is the only cause of the observation, or whether other factors such as temporal interaction also contribute to it. In this study, we used a computational model to investigate channel interaction upon non-simultaneous stimulation with respect to the electrode-ANF distance, and evaluated the SRD performance for five electrode-ANF distances. The SRD performance was determined based on the similarity between two neurograms in response to standard and inverted stimuli and used to evaluate the spectral resolution in the computational model. The spread of excitation was observed to increase with increasing electrode-ANF distance, consistent with previous findings. Additionally, the preceding pulses delivered from neighboring channels induced a channel interaction that either inhibited or facilitated the neural responses to subsequent pulses depending on the electrode-ANF distance. The SRD performance was also found to decrease with increasing electrode-ANF distance. The findings of this study suggest that variation of the neural responses (inhibition or facilitation) with the electrode-ANF distance in CI users may cause spectral smearing, and hence poor spectral resolution. A computational model such as that used in this study is a useful tool for understanding the neural factors related to CI outcomes, such as cannot be accomplished by behavioral studies alone.

RESUMO

Background: The COVID-19 pandemic has affected the world in an unprecedented manner. It has aggravated psychological distress in parents of children with cochlear implants. Continuous use of a speech sound processor is critical for auditory stimulation in children with cochlear implants. However, movement restrictions imposed have affected access to hearing healthcare services. The current study explores the impact of the COVID-19 pandemic on hearing healthcare access for children with cochlear implants. Methods: An online questionnaire survey was conducted among parents of children with cochlear implants. Results: A total of 24 parents responded to the questionnaire. All the respondents reported that COVID-19 has a significant impact on access to hearing health services for their children. Speech processor breakdown and disconnection from the auditory mode of communication had a critical influence on behavioral changes in children. Conclusions: The current study highlights the hurdles faced by the parents in order to access hearing health services for their children. The use of innovative methods such as remote tele-audiology will be the way forward to tackle challenges faced by the parents.

RESUMO

Single-sided deafness(SSD) is a common disease. Compared with normal hearing people, unilateral deaf patients often suffer from the loss of sound source localization ability and speech recognition in complex environments due to the lack of binaural summation effect, squelch effect, spatial demasking effect, and the presence of head shadow effect. Patients' quality of life and professional activities are always poor. Therefore, this article will review the related definitions of SSD, epidemiology, hazards, and artificial hearing aids in the application of SSD patients.

RESUMO

Objective:To compare the efficacy of cochlear implantation in deaf patients with Mondini malformation and normal anatomical structure of inner ear, and to determine whether cochlear implantation can be an effective way to reconstruct hearing in hearing loss patients with Mondini malformation, so as to guide clinical work. Method:Literature search was conducted on PubMed, YZ365. com, Wip medicine, Wanfang data, CHKD, CNKI and other electronic databases to search case control studies on postoperative rehabilitation effect of deafness patients with Mondini deformity and normal structure of inner ear. Execute Meta-analysis by using RevMan 5.3 software. Result:Eleven articles were included and 1 371 patients were involved. Meta-analysis showed that the probability of Mondini abnormalities in patients with intraoperative complications(Z=6.62, P<0.01), electrode reaction T value(Z=6.08, P<0.01), postoperative hearing threshold(500 Hz, 1 000 Hz and 2 000 Hz) is greater than the control group, neural response telemetry(Z=3.44, P<0.01) and categories of auditory performance score(Z=5.27, P<0.01) is lower than the control group, about postoperative complications(Z=1.01, P>0.05) and speech intelligibility rating score(Z=1.41, P>0.05) there was no statistically significant difference with the control group. Conclusion:Cochlear implantation can be a mean of treatment and rehabilitation for deafness patients with Mondini deformity, and is necessary for hearing reconstruction. Further multi-parameter controlled studies with longer follow-up periods and larger samples will increase the credibility for the efficacy of cochlear implants in deafness patients with Mondini malformation.

RESUMO

Speech perception in noise is challenging and is improved by binaural hearing. Since signal processing of assistive hearing devices often modifies or masks the peripheral binaural head-shadow or better-ear effects, central binaural processing should be measured separately. In a prospective study, 10 listeners with normal hearing were tested with the German matrix sentence test in a set-up with two loudspeakers located at opposite angles in the horizontal plane with respect to S0N0. The speech reception threshold (SRT) was investigated depending on the separation angle between speech and noise. The lowest (best) SRT was obtained for a separation of target and interfering source from S0N0 at an angle of about S±60°N∓60°. The derived normative curve was comparable to SRTs predicted by the binaural-speech-intelligibility-model. The systematic separation of signal and noise showed a significant improvement in speech intelligibility for normal-hearing people even for small separation angles. This experimental setting was verified. This study aimed to assess the effect of small sound source separation on binaural hearing and speech perception.

RESUMO

Previous cochlear implant (CI) research has shown that at a pulse train with a long pulse phase duration (PPD) requires less current but greater charge to obtain the same loudness as a pulse train with a short PPD. This might result in different excitation patterns between long and short PPDs. At equal loudness, long PPDs might produce greater masking due to greater charge. However, because they require less current, long PPDs may produce a smaller spatial spread of excitation (SOE) compared to short PPDs by evoking a greater neural firing probability within the relatively small current field. To investigate the effects of PPD on excitation patterns, overall masking and SOE were compared for equally loud stimuli with short or long PPD in 10 adult CI ears. Forward masking patterns were measured at relatively soft, medium, and loud presentation levels. Threshold shifts were calculated in terms of percent dynamic range (DR) of the probe. The area under the curve (AUC) of the masking functions was significantly larger for the long PPD than for the short PPD masker. The difference in AUC was proportional to the difference in charge between the short and long PPD maskers. To estimate SOE, the masking patterns were first normalized to the peak masking, and then AUC was calculated. SOE was significantly larger for the short PPD than for the long PPD masker. Thus, at equal loudness, long PPDs produced greater overall masking (possibly due to greater charge) but less SOE (possibly due to less current spread) than did short PPDs. The effect of the interaction between masking and SOE by long PPD stimulation remains to be tested.

RESUMO

Ten cochlear implant (CI) users with single-sided deafness were asked to vary the parameters of an acoustic sound played to their contralateral ear to characterize the perception evoked by a pure tone played through the direct audio input of their CI. Two frequencies, centered on an apical and a medial electrode, were tested. In six subjects, the electrode positions were estimated on CT scans. The study was divided in 3 experiments in which the parameters of the acoustic sound varied. The listeners had to vary the frequency of a pure tone (Exp.1), the center frequency and the bandwidth of a filter applied to a harmonic complex sound (Exp.2), and the frequency of the components and the inharmonicity factor of a complex sound (Exp.3). Two testing sessions were performed at 3 and 12 months after activation. The mean results of Exp. 1 showed that the frequency of the matched tone was significantly lower for the apical than for the medial stimulus. In Exp.2, the mean center frequencies of the filters were also significantly lower for the apical than for the medial stimulus. As this parameter modifies the energy ratio between the high and low-frequency components, this result suggests that the medial stimulus was perceived with a brighter timbre than the apical stimulus. In Exp.3, the mean frequencies of the components were not significantly different between the sounds resulting from the stimulation of the two electrodes, but were significantly lower at the12-month session compared to the 3-month visit. These results suggest that a change in place of excitation may be perceived as a change in timbre rather than a change in pitch, and that an effect of adaptation can be observed.

RESUMO

OBJECTIVES: In this clinical study, stereo perception of music samples and its contribution to music enjoyment in CI users is investigated. It is studied in free field as well as direct audio presentation. METHODS: 20 bilateral and 9 bimodal CI users performed stereo detection tests and music enjoyment ratings. Music was presented either in mono or in stereo in free field or with direct audio presentation. Stereo detection was assessed with a 3-AFC paradigm. Music enjoyment was studied with scale ratings. RESULTS: For bilateral CI users, stereo detection increased from 52% correct in free field to 86% with direct audio presentation. Increased music enjoyment with improved stereo detection was obtained. Bimodal CI users could not identify stereo sounds. Music enjoyment did not increase for stereo presentations in bimodal subjects. DISCUSSION: For bilateral CI users, improved stereo detection might increase music enjoyment with direct audio presentation, which is likely due to bypassing the room acoustics. In bimodal CI users, no clear improvement was found, which is likely attributed due to the different hearing losses and therefore individually different interaural frequency overlaps between the hearing aid and the cochlear implant. CONCLUSION: Direct audio presentation is an efficient method to improve music enjoyment in bilateral CI users.

RESUMO

INTRODUCCIÓN: Los objetivos del estudio fueron: primero, evaluar la calidad de vida relacionada con la salud (CVRS) de niños y niñas con implantes cocleares (nIC) o audífonos (nAU) de educación primaria de Islas Canarias. Segundo, analizar las percepciones que los progenitores (padres o madres) tenían de la CVRS de los nIC o nAU y finalmente, explorar la homogeneidad de resultados entre los autoinformes de los nIC y nAU y los informes de sus progenitores sobre la CVRS. MATERIAL Y MÉTODOS: Se obtuvieron datos de 89 nIC y 63 nAU y sus 152 progenitores. Se utilizaron 2 instrumentos estandarizados: el Kid-KINDLR_children_7-13, el Kid_Kiddo-KINDLR_Parents_7-17 y un cuestionario con variables demográficas y audiológicas que respondieron nIC y nAU y sus progenitores. Mediante la prueba «t» de Student, ANOVA de una vía, análisis post hoc y 3 coeficientes de correlación de concordancia (CCC) se analizaron los 3 objetivos. RESULTADOS Y DISCUSIÓN: Los nIC mostraron una percepción de mejor CVRS en comparación con los nAU. Los nIC y nAU y sus padres fueron significativamente distintos en las provincias de Tenerife y Gran Canaria. Los nIC y nAU de Gran Canaria obtuvieron mejores resultados en las dimensiones bienestar emocional y familiar, mientras que los nIC y nAU de Tenerife destacaron en autoestima o amigos. Los progenitores de los niños con IC (pIC) tuvieron una puntuación promedio más alta en la percepción de la CVRS total y por dimensiones referida a sus hijos frente a los progenitores de los nAU. El acuerdo entre niños y sus progenitores fue bajo, excepto en la dimensión autoestima. Los nIC y sus progenitores percibieron mejor CVRS que los nAU y sus progenitores. Las autopercepciones de los nIC y nAU de la CVRS fueron inferiores a las informadas por sus progenitores. CONCLUSIONES: Los hallazgos sugieren que los nIC y nAU de educación primaria de las Islas Canarias han mantenido percepciones discrepantes de su CVRS, autopercibiendo los nIC mejor CVRS que los nAU. Los pIC han alcanzado una puntuación promedio más alta de la CVRS de sus hijos que la expresada por los progenitores de nAU por razones de pertenencia a una provincia. Los profesionales que trabajan con los nIC y nAU deben optimizar las dimensiones de la CVRS de los nIC y nAU


INTRODUCTION: The objectives of the study were first, to evaluate the health-related quality of life (HRQoL) of primary school children from the Canary Islands with cochlear implants (CIs) and hearing aids (HAs). And second, to analyse parents' perceptions of their children with CIs and HAs regarding HRQoL, and finally, to explore the agreement between the children's self-reports and their parents' reports concerning HRQoL. MATERIAL AND METHODS: Data consisted of 89 children with CIs and 63 children with HAs and their 152 parents. Two standardised instruments were used: Kid-KINDLR_children_7-13, Kid_Kiddo-KINDLR_Parents_ 7-17 and a demographic and audiological survey, which were answered by the children and their parents. Student's t-test, one-way ANOVA, post hoc analysis and 3 concordance correlation coefficients (CCC) were used to address the 3 objectives. RESULTS AND DISCUSSION: The children with CIs exhibited a perception of better HRQoL in comparison with the children with HAs. The children with CIs and HAs and their parents were significantly distinct in the provinces of Tenerife and Gran Canaria. The cchildren with CIs and HAs from Gran Canaria were better on Emotional well-being and Family, while the children with CIs and HAs from Tenerife emphasised Self-esteem or Friends. The parents of the children with CIs had a higher average score in the perception of the total HRQoL and per dimension related to their children compared to the parents of the children with HAs. The agreement between children and parents was low except in the Self-esteem dimension. The children with CIs and their parents demonstrated a perception of better HRQoL than the children with HAs and their parents. The children with CIs and HAs had lower self-perception of the HRQoL than their parents' reports. CONCLUSIONS: The findings suggest that the children with CIs and HAs in Primary Education in the Canary Islands have discrepant perceptions of their HRQoL; the children with CIs self-perceive better HRQoL than the children with HAs. The parents of the children with CIs achieved a higher average score of their children's HRQoL than the parents of the children with HAs due to their belonging to a province. Professionals working with CI and HA recipients need to be sensitive to psychological issues to optimise HRQoL dimensions in children with CIs and HAs

RESUMO

INTRODUCTION: Patients suffering from severe to profound hearing loss or even deafness can achieve a hearing improvement with a cochlear implant (CI) treatment that is significantly higher than the results achieved with conventional hearing aids. The CI system consists of an implantable stimulator, which is inserted retro-auricularly into the mastoid, and an externally worn processor unit, which provides the pickup of sound and processing of acoustic information as well as the power supply for the stimulator and internal current sources. The stimulator has an electrode array that is inserted into the cochlea. AREAS COVERED: This is a descriptive overview of MED-EL's multichannel CI system (MED-EL, Innsbruck, Austria), which was introduced to the European market in 1994. The continuing development of the implant as well as the external components is outlined and various other aspects (stimulation strategy, adaptation, results, reliability) are discussed. EXPERT COMMENTARY: The strength of the company is the continuous pursuit of innovative ideas. This is evidenced by numerous innovations. The reliability of the implants has been continuously improved. The current SYNCHRONY models of the manufacturer show no indication of technically caused failures over an observation period of 5 years.

RESUMO

The aim of the present study was to compare the posterior tympanotomy (PT) technique to the endomeatal approach. The endomeatal approach (EMA) for Cochlear Implant (CI) surgery was performed on 98 patients with procident lateral sinus or a small mastoid cavity, on 103 ears (Group A). Conventional mastoidectomy and PT was performed on the other 104 patients, on 107 ears (Group B). Data on all patients were then collected for the following: intra- and post-operative complications, Tinnitus Handicap Inventory (THI), Vertigo Symptom Scale (VSS), duration of surgery, and postoperative discomfort. The difference in the total number of major and minor complications between the case group and the control group was not statistically significant. There was a statistically significant difference in discomfort between the two groups using the Visual Analogue Scale (VAS), both immediately postsurgery (p = 0.02) and after one month (p = 0.04). The mean duration of surgery was 102 ± 29 min for EMA and 118 ± 15 min for the PT technique (p = 0.008). EMA is a faster technique resulting in reduced postoperative patient discomfort in comparison to the PT method. The experience of the surgeon as well as the correct choice of surgical technique are fundamental to successful outcomes for cochlear implant surgery.
