远距离与噪声环境下人工耳蜗适配无线调频系统对听障儿童聆听效果的影响
Effects of Cochlear Implant with Wireless Listening System on Listening Outcomes in Hearing-Impared Children in Long-Distance and Noisy Environments
摘要
Abstract
Objective To evaluate the efficacy of cochlear implant-compatible wireless listening systems(CI+FM)in improving listening outcomes in preschool-aged children with hearing impairment under long-distance and noisy conditions.Methods A comparative study was conducted involving 182 children with hearing loss(aged 3-6 years)enrolled in auditory training across 17 grassroots rehabilitation institutions in Guangdong Province.Listening performance was compared between CI+FM and CI alone conditions using questionnaires,speech detection tasks,and auditory-verbal assessments.Testing was conducted at different distances(2 m,10 m,25 m,and 50 m)and signal-to-noise ratio(SNR)environments(− 15 dB,0 dB,20 dB).Results For Long-distance listening:at 2 m distance,no significant difference in Ling's five-sound detection rates was observed between the two modes(P=1.000).However,at distances of 10 m,25 m,and 50 m,the CI+FM mode showed significantly higher detection rates than the CI alone mode(all P<0.001),with optimal effectiveness within 25 m distance.For Listening in noisy environments:under SNR conditions of − 15 dB,0 dB,and 20 dB,the CI+FM mode showed significantly higher recognition rates for both consonant and disyllabic words compared with the CI-alone mode(all P<0.05).The most pronounced improvement was observed at −15 dB SNR.For Questionnaire survey:the scores for the CI+FM mode were significantly higher than the CI mode in the both noisy environment and long-distance scenarios(both P<0.01).Conclusion The CI+FM mode significantly improves listening outcomes in children with hearing impairment across long-distance(10～50 m)and noisy environments(SNR − 15 dB to 0 dB),with optimal effectiveness within 25 m distance.These findings support the integration of FM technology as an effective assistive tool for optimizing auditory access during outdoor instruction and group activities in the pediatric population with hearing impairment.关键词
