激活通道数对现代人工耳蜗植入者言语感知影响的初步研究
Effects of the number of active channels on speech perception in modern cochlear implant recipients
摘要
Abstract
Objective This study aims to evaluate the effect of manipulating the number of active channels on speech perception in modern cochlear implant recipients.Methods Ten postlingually deafened adult patients with unilateral Nurotron cochlear implants who presented to the Department of Otolaryngology,Henan Provincial People's Hospital from November 2020 to November 2023 were enrolled.Their speech outcomes were assessed by measuring speech perception performance with 8,12,16,22 or 24 channels activated and under both quiet and+5 dB signal-to-noise ratio conditions.The assessments included the Mandarin Speech Perception(MSP)sentence recognition test,as well as subjective ratings of sound clarity and sound quality.Results As the number of active channels increased,there was a significant overall improvement in MSP sentence recognition,sound clarity,and sound quality ratings in quiet(P<0.05).In contrast,significant difference was observed only in MSP sentence recognition scores between 12 and 24 channels in noise(P=0.019).Conclusions Speech perception in quiet improves with an increasing number of active channels up to 24 in modern cochlear implant recipients.However,the relationship between the number of active channels and speech perception in noise warrants further examination.关键词
