Speech recognition and real-ear-measured amplification in hearing-aid users with various grades of hearing loss.

Objective: The relationship between aided speech recognition and hearing-aid (HA) amplification was investigated in a retrospective study.

Design And Study Sample: Pure-tone thresholds, aided and unaided speech recognition and real-ear measurements of 635 ears in 374 HA users were reviewed. Ears were classified according to pure-tone average (PTA) and real-ear aided response (REAR) in relation to the targets of NAL-NL2 and DSL v5.

[Disproportionately high loss in speech intelligibility].

Background: The influence of hearing impairment on everyday hearing can be estimated by speech audiometry. There is a great deal of variability in the dependence of word recognition scores on pure-tone hearing loss.

Materials And Methods: A large clinical database of 28,261 records with complete tone and speech audiometry data was analyzed.

Illness perceptions in cochlear implant users - a longitudinal study.

Purpose: 'Illness perceptions' refers to the thoughts and ideas a person has about an illness. According to Leventhal's Self-Regulatory Model (SRM), changing the threatening illness perceptions of cochlear implant (CI) recipients can be a further step in optimizing hearing outcomes with the CI. The aims of the present study were to assess users' illness perceptions and to determine whether perceptions change during six months of CI rehabilitation.

Impact of unilateral vs. bilateral evaluation on cochlear implant candidacy.

Background: The indication criteria for cochlear implantation differ considerably across regions.

Objectives: To estimate the effects of different candidacy criteria on the number of cochlear implant (CI) candidates.

Methods: We analysed a very large clinical audiological database comprising pure-tone thresholds and speech-audiometric data in order to identify CI candidates on the basis of different audiometric candidacy criteria.

Associations between illness perceptions, word recognition, and perceived sound quality in cochlear implant users.

Objective: Illness perceptions refer to thoughts and ideas an individual has about an illness. The aim was to understand how cochlear implant (CI) users' illness perceptions, in addition to their monosyllabic word recognition abilities, are associated with their self-perceived sound quality.

Design: Data were collected during routine CI check-up appointments.

Surgical Versus Noninvasive Manual Repositioning After Cochlear Implant Partial Magnet Dislocation.

To compare surgical magnet repositioning (SMR) and noninvasive manual magnet repositioning (MMR) as treatments for partial magnet dislocation (PMD) of the internal magnet in a cochlear implant (CI) caused by magnetic resonance imaging (MRI). The primary objective was the success rate, while the secondary objectives were total postinterventional CI downtime and complications. This single-center retrospective study was conducted at a tertiary referral medical center.

Electrically evoked compound action potentials in cochlear implant users with preoperative residual hearing.

Introduction: Residual hearing in cochlear implant (CI) candidates requires the functional integrity of the nerve in particular regions of the cochlea. Nerve activity can be elicited as electrically evoked compound action potentials (ECAP) after cochlear implantation. We hypothesize that ECAP thresholds depend on preoperative residual hearing ability.

Evolving a Model for Cochlear Implant Outcome.

Background: Cochlear implantation is an efficient treatment for postlingually deafened adults who do not benefit sufficiently from acoustic amplification. Implantation is indicated when it can be foreseen that speech recognition with a cochlear implant (CI) is superior to that with a hearing aid. Especially for subjects with residual speech recognition, it is desirable to predict CI outcome on the basis of preoperative audiological tests.

Validation of a predictive model for speech discrimination after cochlear impIant provision.

Background: If sufficient speech discrimination is no longer achieved with conventional hearing systems, an audiological indication for a cochlear implant (CI) is given. However, there are no established target criteria for CI aftercare with regard to the level of speech comprehension to be achieved. The aim of this study is to validate an existing predictive model for speech comprehension after CI provision.

Risk of magnetic resonance imaging-induced magnet dislocation for different types of cochlear implants: a single-center retrospective study.

Background: When performing magnetic resonance imaging (MRI) in patients with a cochlear implant (CI), complication rates vary widely in the literature. The primary objective of this retrospective study was to determine the prevalence of complications, in particular magnet dislocation, in patients with CI undergoing 1.5 Tesla (T) MRI.

[Validation of a predictive model for speech discrimination after cochlear implant provision].

Background: If sufficient speech discrimination is no longer achieved with conventional hearing systems, an audiological indication for a cochlear implant (CI) is given. However, there are no established target criteria for CI aftercare with regard to the level of speech comprehension to be achieved. The aim of this study is to validate an existing predictive model for speech comprehension after CI provision.

Challenging social media threats using collective well-being-aware recommendation algorithms and an educational virtual companion.

Social media have become an integral part of our lives, expanding our interlinking capabilities to new levels. There is plenty to be said about their positive effects. On the other hand, however, some serious negative implications of social media have been repeatedly highlighted in recent years, pointing at various threats to society and its more vulnerable members, such as teenagers, in particular, ranging from much-discussed problems such as digital addiction and polarization to manipulative influences of algorithms and further to more teenager-specific issues (e.

Association between lateral wall electrode array insertion parameters and audiological outcomes in bilateral cochlear implantation.

Purpose: The aims of this study were to compare speech recognition at different postoperative times for both ears in bilaterally implanted patients and to assess the influence of the time of deafness, frequency-to-place mismatch, angular insertion depth (AID) and angular separation between neighbouring electrode contacts on audiometric outcomes.

Methods: This study was performed at an academic tertiary referral centre. A total of 19 adult patients (6 men, 13 women), who received sequential bilateral implantation with lateral wall electrode arrays, were analysed in retrospective.

Developing a framework for investigating citizen science through a combination of web analytics and social science methods-The CS Track perspective.

Over the past decade, Citizen Science (CS) has shown great potential to transform the power of the crowd into knowledge of societal value. Many projects and initiatives have produced high quality scientific results by mobilizing peoples' interest in science to volunteer for the public good. Few studies have attempted to map citizen science as a field, and assess its impact on science, society and ways to sustain its future practice.

Children with cochlear implant and additional disabilities benefit from consistent device use.

Objectives: Although the prevalence of additional disabilities (AD) in children with a cochlear implant (CI) is high, children with such disabilities are often excluded from clinical studies, or their specific characteristics are only partially included. The literature shows that several factors need to be considered in evaluating auditory and language development in CI children with AD, including demographic variables as well as the severity and type of disability. Current findings on device use in children show correlations with auditory and language outcome, but little is known about device use specifically in children with AD.

[Word production in children with cochlear implant based on chronological age and hearing age].

Background: For congenitally deaf children, an early bilateral provision with cochlear implant (CI) is a favourable condition for language acquisition. The objective of the present study was to determine the word production in CI children. The focus was on a comparison of chronological age and hearing age performance and on the evaluation of potential effects of multilingualism, additional disabilities and age at provision.

Age-Related Decline of Speech Perception.

Hearing loss is one of the most common disorders worldwide. It affects communicative abilities in all age groups. However, it is well known that elderly people suffer more frequently from hearing loss.

Prediction of Speech Intelligibility by Means of EEG Responses to Sentences in Noise.

Objective: Understanding speech in noisy conditions is challenging even for people with mild hearing loss, and intelligibility for an individual person is usually evaluated by using several subjective test methods. In the last few years, a method has been developed to determine a temporal response function (TRF) between speech envelope and simultaneous electroencephalographic (EEG) measurements. By using this TRF it is possible to predict the EEG signal for any speech signal.

Evaluation of a Transimpedance Matrix Algorithm to Detect Anomalous Cochlear Implant Electrode Position.

Introduction: Transimpedance measurements from cochlear implant electrodes have the potential to identify anomalous electrode array placement, such as tip fold-over (TFO) or fold-back, basal electrode kinking, or buckling. Analysing transimpedance may thus replace intraoperative or post-operative radiological imaging to detect any potential misplacements. A transimpedance algorithm was previously developed to detect deviations from a normal electrode position with the aim of intraoperatively detecting TFO.

Speech Perception in Bilateral Hearing Aid Users With Different Grades of Asymmetric Hearing Loss.

Hearing loss is associated with decreased speech perception as well as with changes in the auditory pathway. The effects of those changes on binaural speech perception with hearing aids are not yet fully understood. To provide further evidence on the functional changes of the auditory pathway, several speech perception tests (unilateral and bilateral, aided and unaided, in quiet, and in noise) were conducted in a population of 370 bilateral hearing aid users covering the entire range of the World Health Organization's most recent classification of hearing loss.

[Effectiveness of hearing aid provision for severe hearing loss].

Background And Objective: In practice, the unilateral monosyllabic speech recognition score with hearing aid (WRS(HA)) is often below the maximum word recognition score with headphones (WRS), in particular for subjects with severe hearing loss. The aim of this study was to evaluate the efficiency factor Q of hearing aid provision, the ratio WRS(HA)/WRS, in patients with severe to profound hearing loss.

Materials And Methods: Data from real-ear measurements (REM), pure tone and speech audiogram, and speech recognition with and without hearing aid of 93 ears in 64 patients were examined.

A Virtual Sandbox Approach to Studying the Effect of Augmented Communication on Human-Robot Collaboration.

Human-Robot Collaboration (HRC) has the potential for a paradigm shift in industrial production by complementing the strengths of industrial robots with human staff. However, exploring these scenarios in physical experimental settings is costly and difficult, e.g.

Diagnosing complications following cochlear implantation using transcutaneous ultrasound.

Purpose: The aim of this study was to investigate the feasibility and reliability of transcutaneous ultrasound for the detection of complications after cochlear implantation.

Methods: In a single center retrospective cohort study, 115 consecutive cases of suspected complications after cochlear implantation (intervention group) were examined. The rate of pathologic ultrasound findings for specific leading symptoms and diagnoses was compared to a control group comprising twenty consecutive cochlear implants in symptom-free patients.
