Summary: Cochlear implants (CIs) offer the hearing impaired a chance to perceive sound through electrical stimulation of the cochlear nerve. However, CI surgery carries a high risk of losing natural hearing, which can impact speech perception and music appreciation. Electrocochleography (ECochG) has been used to detect trauma during surgery and potentially save natural hearing. This study discusses an automated method for analyzing cochlear responses during CI surgeries, demonstrating high accuracy compared to human experts and the potential to improve ECochG scalability and patient safety.

Summary: This study aimed to investigate the postoperative course of residual acoustic hearing and clinical impedance in patients with long electrode arrays and to explore the applicability of impedance telemetry for monitoring residual hearing. The results showed that residual hearing may be lost within 6 months postoperatively, and clinical impedance gradually decreased over time. Basal electrodes were more likely to have higher impedance. Furthermore, the study found a significant association between clinical impedance and residual hearing.

Summary: This study aimed to test the utility of two different patient reporting outcome (PRO) measures in cochlear implant (CI) users and identify items for specific music rehabilitation programs. The results showed good consistency between the PRO measures and correlations with some audiological outcomes. 63% of patients expressed a willingness for musical rehabilitation. Therefore, the application of MUSQUAV and NCIQ is supported to improve the clinical and audiological evaluation of CI patients.

Summary: This study investigates the effects of time-synchronized facial information on vocal emotion recognition (VER) and finds that cochlear implant (CI) users perform worse in emotion classification tasks compared to individuals with normal hearing. The study also finds that CI users show larger benefits to VER when facial information is congruent with the auditory information, suggesting that they compensate for their auditory impairment through crossmodal integration.

Summary: Cochlear implants have been successful in restoring speech perception for severely to profoundly deaf individuals, but limitations remain in understanding speech in noisy environments, locating sound sources, and enjoying music. Electro-haptic stimulation (EHS) has shown to improve speech-in-noise performance and sound localization in CI users, with potential for enhancing music perception. Further research is needed to understand the neural basis of EHS enhancement and its effectiveness across different clinical populations, as well as to optimize signal-processing strategies for future haptic neuroprosthetic devices in aiding hearing-impaired individuals.

Summary: Hearing loss is considered a modifiable risk factor for cognitive decline, and cochlear implantation has been shown to improve cognitive functions in individuals with severe hearing impairment. This study demonstrated that cognitive functions significantly increased after cochlear implantation, and cognitive reserve had a positive correlation with cognitive functions. Depression had a slight influence on cognitive functions, and there was no correlation between cognitive skills, quality of life, and speech perception.

Summary: The study aimed to evaluate the impact of speech audibility on speech recognition with frequency composition in hearing aids. Participants, including children and adults with hearing loss, were tested for word and sentence recognition thresholds with and without frequency composition. Results showed that better aided speech audibility led to better speech recognition in noise, and changes in word recognition threshold in children were predictable from aided speech audibility. Further research is needed to generalize these findings to a larger participant pool and different stimuli.

Summary: The medial olivocochlear reflex (MOCR) is a physiological mechanism in the auditory system that adjusts sensitivity to sound. The characteristics of the elicitor can affect the reduction of cochlear gain, showing that the excitation at the cochlear place determines the magnitude of gain reduction and increases with the level of the elicitor.

Summary: This study aimed to investigate the relationship between speech recognition in noise, age, hearing ability, self-rated listening effort, inhibitory control, and working memory capacity. Results showed that high WMC was related to lower self-rated listening effort for informational maskers and better performance in speech recognition in noise with informational maskers. The linear mixed-effects model revealed differences in performance between low-context and high-context speech materials, and the various maskers used.

Summary: Background noise can make listening more difficult and lead to fatigue, especially for non-native speakers. In this study, it was found that non-native speakers showed greater pupil dilation, indicating more listening effort, in typical listening conditions compared to native speakers. Native speakers were able to apply listening effort effectively, while non-native speakers may have reached their effort limit, resulting in poorer listening comprehension. Additionally, baseline pupil size decreased over trials, suggesting increased listening-related fatigue, particularly in typical listening conditions.

Summary: This study aimed to evaluate the differences in analogical reasoning ability between children with cochlear implants (CI) and children with typical hearing (TH), and to explore whether these differences could be explained by differences in language ability. The results showed that children with CI performed comparable to children with TH on non-verbal reasoning tasks but significantly worse on verbal analogical reasoning tasks. This suggests that verbal strategies may influence the performance of children with CI on non-verbal analogical reasoning tasks with high relational integration demand.

Summary: There is a lack of research on reading decoding skills among clinical samples of Swedish-speaking children with Developmental Language Disorder (DLD). This study found that only 18% of the children with DLD had age-appropriate decoding skills. Working memory and nonword repetition were the best predictors of decoding skills, followed by school year. Family history of literacy problems did not contribute to the variance in decoding. These findings highlight the importance of assessing and monitoring literacy development in children with DLD.
