Currently, most people with modern multichannel cochlear implant systems can understand speech in qui-et environment very well. However, studies in recent decades reported a lack of satisfaction in music percep-tion with cochlear implants. This article reviews the literature on music ability of cochlear implant users by presenting a systematic outline of the capabilities and limitations of cochlear implant recipients with regard to their music perception as well as production. The review also evaluates the similarities and differences be-tween electric hearing and acoustic hearing regarding music perception. We summarize the research results in terms of the individual components of music (e.g., rhythm, pitch, and timbre). Finally, we briefly intro-duce the vocal singing of prelingually-deafened children with cochlear implants as evaluated by acoustic measures.

The purpose of the present study was two-fold:(1)to examine whether Mandarin-speaking children with cochlear implants(CIs)show distinctive durational and amplitude features for the four lexical tones in their tone production;(2)to compare the durational and amplitude patterns of Mandarin lexical tones in monosyllables produced in citation form by children with CIs with those by age-matched normal-hearing(NH)children.The participants included 14 prelingually deafened Mandarin-speaking children with CIs and 14 NH children,all aged between 2.9 and 8.3 years old.Each participant produced five CV syllables(fa/fa/,fu/fu/,pi/phi/,xu/y/,ke/kh/)in four tones through a tone drill activity.The vowel duration and root-mean-squared amplitude values at nine equidistant time locations over the vowel duration were obtained.The results revealed that the children with CIs produced distinctive durational and amplitude features for the four lexical tones.Their durational pattern and amplitude contours were highly similar to the NH children on tones 1,2 and 4 but differed from the NH children on tone 3.These findings suggested that the children with CIs may utilize the secondary features of tone duration and amplitude to realize tonal differences.

Objective:To provide an overview of the current available music assessment tools after cochlear implantation(Cl);to report on the utilization of music assessments in the literature;to propose potential future directions in music assessment after Cl.Methods:A thorough search was performed in PubMed,Embase,and The Cochrane Library through October 31,2020.MeSH search terms,keywords,and phrases included“fcochlear implant,”“fcochlear prosthesis,”“auditory prosthesis,”“music,”“music assessment,”“music questionnaire,”“music perception,”“musk enjoyment,and,fmusic experience.”Potentially relevant studies were reviewed for inclusion,with particular focus on assessments developed specifically for the cochlear implant population and intended for widespread use.Results/conclusions:Six hundred and forty-three studies were screened for relevance to assessment of music experience among cochlear implantees.Eighty-one studies ultimately met criteria for inclusion.There are multiple validated tools for assessment of music experience after cochlear implantation,each of which provide slightly differing insights into the patients1 subjective and/or objective post-activation experience.However,no single assessment tool has been adopted into widespread use and thus,much of the literature pertaining to this topic evaluates outcomes non-uniformly,including single-use assessments designed specifically for the study at hand.The lack of a widely accepted universal tool for assessment of music limits our collective understanding the contributory and mitigating factors applicable to current music experience of cochlear implantees,and limits our ability to uniformly evaluate the success of new implant technologies or music training paradigms.

cochlear implantation is one of the best amongst the various management options available for children and adults with severe to profound sensorineural hearing loss.Inner ear and internal auditory canal(IAC) malformations accounts to approximately 25% of congenital sensorineural hearing loss in children.The primary goal of this report was to evaluate the communication outcomes after cochlear implantation in a child with cystic cochleovestibular anomaly(CCVA).The child was evaluated through various standardized outcome measures at regular intervals to track the progress in terms of auditory and spoken language skills.The scores on Categories of Auditory Perception(CAP),Meaningful Auditory Integration Scale(MAIS),Speech Intelligibility Rating(SIR),Meaningful Use of Speech Scale(MUSS),and listening and spoken language skills showed a significant leap in 12 months duration post implantation.The report thus highlights and correlates the significant progress in auditory and spoken language skills of the child with congenital malformations to appropriate auditory rehabilitation and intensive parental training.

Global demographic changes related to longevity are leading to increasing numbers of the elderly, for whom hearing loss is a significant cause of morbidity and disability. Once met with reticence, severely hearing impaired older adults are increasingly being considered for cochlear implantation (CI). Significant data indicate that CI in the elderly population is safe, well-tolerated, and effective. Risks from CI surgery and anesthesia are low and generally comparable to rates in other age groups. Outcomes studies regarding CI in older adults have shown excellent improvements to speech perception, quality of life, and even cognition. Overall, currently available data suggests that advanced age should not, in itself, be considered a barrier to implantation. This review paper will highlight selected articles from recent medical literature regarding the safety and efficacy of CI in the elderly population.

AIM:To find out effect of different signal-to-noise ratios(SNRs) on word perception at different number of channels.METHODS: Thirty participants with normal hearing in the age range of 18-25 years(mean age 23.6 years) were involved in the study. For word perception test, there were 28 key-words embedded in sentences comprises of four lists processed for different channels(4, 8 and 32 channel) using AngelS im program at-5, 0 and +5 SNRs. The recorded stimuli were routed through audiometer connected with computer with CD player and presented in free field condition with speakers kept at 0° azimuth in a sound treated room.RESULTS: Repeated measure ANOVA showed significant main effect across different SNRs at 4 channel, 8 channel and at 32 channel. Further, Bonferroni multiple pairwise comparisons shows significant differences between all the possible combinations(4, 8 and 32 channel) at +5 dB SNR, 0 dB SNR and-5 dB SNR.CONCLUSION: Present study highlights the importance of more number of channels and higher signal to noise ratio for better perception of words in noise in simulated cochlear implantees.

Background: cochlear implants (CI) are widely used to restore hearing in people with severe to profound hearing loss. However, optimizing CI performance, especially in difficult listening environments with background noise, remains a major challenge. Understanding the influence of factors such as sound source position and electrode placement on CI stimulation patterns is critical to improving auditory perception. Methods: In this study, an analysis was conducted to investigate the influence of sound source position and electrode placement on CI stimulation patterns under noisy conditions. For this purpose, a special measurement setup with a CI speech processor-microphone test box was used to simulate realistic listening scenarios and measure CI performance. Results: The results show that the effectiveness of CI noise reduction systems is influenced by factors such as the position of the sound source and electrode placement. In particular, the beamforming ultra zoom mode showed significantly better noise reduction than the omnidirectional mode, especially under real listening conditions. Furthermore, differences in electrode responses indicate individual variability in the CI user experience, highlighting the importance of personalized fitting algorithms. Conclusions: The results demonstrate the importance of considering environmental factors and individual differences when optimizing CI performance. Future research efforts should focus on the development of personalized fitting algorithms and the exploration of innovative strategies, such as the integration of artificial intelligence, to improve CI functionality in different listening environments. This study contributes to our understanding of CI stimulation patterns and lays the foundation for improving auditory perception in CI users.

Introduction: Deafness, is the most common neurosensory deficit in humans. The origins can be diverse: congenital or acquired and sometimes of an etiology that is difficult to specify. The main risk is social exclusion. The advent of cochlear implants is a solution of choice for severe to profound sensorineural hearing loss. This innovative therapeutic modality is new to Cameroon, so we proposed to evaluate the preliminary results of cochlear implantation at the General Hospitals of Yaoundé and Douala, by addressing the epidemiological, clinical and paraclinical, surgical, and prosthetic aspects. Methodology: We conducted a descriptive and prospective cross-sectional study over a period of two years and eight months, from January 2019 to 31 August 2021. The study sites were: the general hospitals of Yaounde and Douala, as well as the private practices of speech therapists in the said cities. We collected socio-demographic, clinical, paraclinical variables and data on surgical, prosthetic and speech therapy management which were processed. Results: We recruited 15 cochlear implant patients, one adult and 14 children. The sex ratio was 1.14 in favour of girls, the average age of the child population was 4.9 years and one subject was 57 years old. These children were mostly in school (85.7%) and mostly (86.7%) living in urban areas. The average period of sound deprivation was 3.9 years. The deafness of the children was 100% prelingual and the acquired cause was evoked in front of the risk factors (prematurity, low birth weight, neonatal asphyxia, jaundice, meningitis, neuromalaria) for 57.7% of them. The adult deafness was postlingual and post-traumatic. The associated clinical conditions found in 4 (26.8%) of the patients were an ocular refraction disorder, a chronic otitis media sequelae, cerebral palsy and minor head trauma injuries. There was no syndromic or malformative picture. The deafness was bilateral in all cases, asymmetric in 22.2% of cases and severe to profound sensorineural. The threshold of the deafn
