【摘要】：目的:采用去除时长信息的声调测试材料评估语后聋人工耳蜗植入者依靠音调信息识别声调的能力。方法:16例成人语后聋患者单侧植入人工耳蜗6个月以上。选取10个单音节,每个音节配4个声调,组成40个单音节词,分别由男女声多次录制,选取四声之间时长差别5ms的80个单音节词为测试词,受试者根据听到的单音节词完成四选一的测试。结果:16例人工耳蜗植入者声调识别总平均得分为(70.7±22.0)%,其中四声得分最高,二声得分最低。一声易被混淆成二声,二声易被混淆成一声和三声,三声易被混淆成二声,四声最不易被混淆。声调识别得分与助听器使用时间呈正相关。结论:去掉时长因素对人工耳蜗植入者声调识别能力有所影响,对三声识别影响最显著。由于人工耳蜗植入者音调信息感知能力有限,因此在没有时长因素辅助的情况下,其一声与二声,二声与三声的辨别最易混淆。语后聋人工耳蜗植入者在植入人工耳蜗前佩戴助听器的经历有益于人工耳蜗植入后的声调识别。
[Abstract]:Objective: to evaluate the ability of cochlear implants to recognize tones by tone information in patients with postlingual deafness by using tone test materials. Methods: sixteen adult patients with postlingual deafness underwent unilateral cochlear implantation for more than 6 months. Ten monosyllables were selected. Each syllable was composed of 40 monosyllable words, which were recorded by male and female vocals many times, and 80 monosyllabic words with 5 Ms duration difference between four sounds were selected as test words. According to the monosyllabic words they heard, the subjects completed the test of four choices and one. Results the total average score of tone recognition in 16 cases of cochlear implants was 70.7 卤22.0, with the highest score of four tones and the lowest score of two tones. Two sounds are easily confused into one sound and three sound, three sound is easy to be confused into two sounds, The score of tone recognition was positively correlated with the duration of hearing aid use. Conclusion: removing the factors of length of time may affect the tone recognition ability of cochlear implants. Because of the limited ability of perception of tone information in cochlear implants, the first and second tones of cochlear implants are not supported by long-term factors. The experience of hearing aids before cochlear implantation is beneficial to the tone recognition of cochlear implants.
