Article Abstract
Purpose: Magnetic resonance imaging (MRI), electric compound action potential (eCAP), and electric auditory brainstem response (eABR) are among the routine assessments performed before and/or after cochlear implantation. The objective of this review was to systematically summarize and critically appraise existing evidence of the prognostic value of eCAP, eABR, and MRI for predicting post-cochlear implant (CI) speech perception outcomes in children, with a particular focus on the lesion site.
Method: The present systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. Three electronic databases (ProQuest, PubMed, and Scopus) were searched with no restrictions on language, publication status, or year of publication. Studies on children identified with sensorineural hearing loss, auditory neuropathy spectrum disorder, cochlear nerve deficiency, or cochleovestibular nerve abnormalities reporting the relevance of eCAP, eABR, and/or MRI results to CI speech perception outcomes were included. The literature search yielded 1,887 publications. Methodological quality and strength of evidence were assessed by the Crowe Critical Appraisal Tool and the Grading of Recommendations Assessment, Development, and Evaluation tool, respectively.
Results: Of the 25 included studies, the relevance of eCAP, eABR, and/or MRI findings to post-CI speech perception outcomes was reported in 10, 11, and 11 studies, respectively. The studies were strongly in support of the prognostic value of eABR and MRI for CI outcomes. However, the relevance of eCAP findings to speech perception outcomes was uncertain.
Conclusion: Despite the promising findings, caution is warranted in interpreting them due to the observational and retrospective design of the included studies, as well as the heterogeneity of the population and the limited control of confounding factors within these studies.

No Association Between Vocal Emotion Recognition and Subjective Parental Reporting of Alexithymia in School-Age Children With Hearing Aids.

Department of Otorhinolaryngology, University Medical Center Groningen (UMCG), University of Groningen, Groningen, the Netherlands.
Objectives: Alexithymia is characterized by difficulties in identifying and describing one's own emotions. Alexithymia has previously been associated with deficits in the processing of emotional information at both behavioral and neurobiological levels, and some studies have shown elevated levels of alexithymic traits in adults with hearing loss. This explorative study investigated alexithymia in young and adolescent school-age children with hearing aids in relation to (1) a sample of age-matched children with normal hearing, (2) age, (3) hearing thresholds, and (4) vocal emotion recognition.

This study focuses on suprasegmental features and investigates how the use of a second tonal dialect influences the production of tones in the first dialect among bidialectal speakers of Chengdu Mandarin (CM) and Standard Mandarin (SM). Using a word-naming task, this study analyzed the acoustic differences between tones in SM and CM that share similar pitch contours and assessed the impact of SM use on CM tone production. How bidialectal listeners perceptually map SM tones onto CM categories was further evaluated using a dissimilarity rating task.

The Zwicker tone (ZT) is an auditory illusion experienced by about 50% of the population immediately following a presentation of notched noise (NN). It is a faint, quickly decaying pure tone, the frequency of which falls within the range of the notch. Interestingly, although only half of the general population can perceive ZTs, one study has shown that almost everyone with tinnitus can perceive them.

Introduction: A significant challenge for some transgender and gender diverse (TGD) individuals is that their voice and communication do not align with their gender identity or the way they wish to be perceived. Voice and communication training (VCT) can address key factors that are the most salient in gender perception, such as pitch, resonance, articulation, and intonation. While intonation training has proven its benefits for developing a feminine-sounding voice, its impact on achieving a masculine-sounding voice remains underexplored.

Purpose: This study aimed to evaluate the impact of different hearing devices on sound localization and speech perception in individuals with single-sided deafness (SSD). Specifically, the study sought to assess the performance of softband bone-anchored hearing aids (BAHAs) and contralateral routing of signals hearing aids (CROS HA) in various conditions to determine their effectiveness in improving auditory outcomes for SSD patients.
Method: Eighteen participants (aged between 20 and 50 years) with SSD underwent tests using softband BAHA, CROS HA, and unaided conditions in a counterbalanced design.
