人工耳蜗植入患者对西洋乐器和民族乐器感知研究

The timbre perception of western musical instruments and national instruments in cochlear implant users

目的分析人工耳蜗植入患者对西洋乐器和我国民族乐器感知能力的差异,探讨人工耳蜗植入者与听力正常者在音乐音色感知的规律特征和听配能差异。方法耳蜗组和对照组受试者各20例,使用音乐感知评估平台对两组受试者进行音色识别能力测试,记录并比较两组音色识别正确率和总应答反应时间。结果①耳蜗组音色识别正确率(80.42±11.87)%,显著低于对照组正确率(96.67±4.19)%,差异具有统计学意义(P<0.01)。②耳蜗组对我国民族乐器(琵琶、二胡)识别正确率82.50%,西洋乐器正确率80.00%,两者差异无统计学意义(P=0.664)。③耳蜗组对音色测试总应答反应时间(170.50±21.81)s,与对照组(161.85±18.18)s比较,差异无统计学意义(t=1.363,P>0.05)。结论人工耳蜗植入患者对音乐音色的感知能力显著低于听力正常者,在测听任务过程中所需听配能增加,并且容易混淆管弦乐器。对比西洋乐器,人工耳蜗植入患者对我国民族乐器的感知无明显优势。

Objective To analyze the timbre perception of western musical instruments and Chinese national musical instruments in cochlear implant users,and investigate the different characteristics of musical timbre identification and listening effort between cochlear implant users and normal hearing listeners.Methods 20 cochlear implant users and 20 normal hearing listeners were enrolled in this study.The music perception assessment platform was used to evaluate their timbre recognition,and their accuracy of timbre recognition and the response time were recorded and analyzed.Results①The accuracy of timbre recognition of cochlear implant subjects was(80.42±11.87)%,which was significantly lower than that of the control group[(96.67±4.19)%](P<0.01).②The cochlear implant users got recognition correct rates of 82.50%for Chinese national musical instruments(pipa and erhu)and 80.00%for western musical instruments,the difference was statistically insignificant(P=0.664).③For cochlear implant subjects,the average response time was(170.50±21.81)s,while it was(161.85±18.18)s in the control group,and the difference was also statistically insignificant(t=1.363,P>0.05).Conclusions The cochlear implant users perform significantly poorer with greater listening effort than normal hearing peers in the timbre perception test.They are easy to confuse the orchestral instruments.They have no obvious advantage on the perception of Chinese national musical instruments contrast to western musical instruments.
