摘要
本研究采用三因素混合实验设计,比较了人工耳蜗儿童(CI)与助听器儿童(HA)在不同信噪比条件下(SNR=10,5,0),对不同难度材料(双音节词和短句)的选择性听取能力。研究结果表明:(1)在重建听阈与补偿听阈相似时,人工耳蜗儿童与助听器儿童的选择性听取能力的差异不显著;(2)两类儿童对词语和短句的选择性听取能力差异显著;(3)在不同信噪比条件下两类儿童的择性听取能力差异显著。本研究结果提示,若助听器能补偿到最适宜水平,则没有必要进行人工耳蜗植入。
To investigate the difference of selective listening ability between children with cochlear implants and with hearing aids,this study has designed three-factor experiments,including the types of children,materials（diphthongs and shorf sentences）,and signals to noise ratio（SNR）.The results show that：1） the score of selective listening has no significant difference between children with cochlear implants and children with hearing aids;2） there is significant difference of the selective listening between diphthongs and short sentences;3） for SNR,there is also a significant difference.Those findings indicate that if hearing aids can meet children＇s need,it is not necessary to give them cochlear implants.
