不同听觉干预手段对聋儿声调辨别能力的影响

目的了解聋儿对声调的识别能力,以指导聋儿的言语康复训练。方法将受试对象分为3组:人工耳蜗组、助听器组和对照组。人工耳蜗组和助听器组均为双耳重度或极重度听力损失患儿。人工耳蜗组43例,其中男20例,女23例,人工耳蜗植入年龄在2.5～7岁;助听器组41例,男22例,女19例;对照组28例为听力正常儿童,男13例,女15例,年龄3～6岁。测试3组儿童对单音节词声调、扬扬格词声调的识别能力。结果人工耳蜗组对单音节词、扬扬格词声调的识别能力显著优于助听器组(P<0.01),但弱于正常对照组(P<0.01)。结论不同的听觉干预手段对聋儿声调识别能力有影响,人工耳蜗对重度或极重度听力损失的儿童较助听器有更好的声调识别能力。

The influence of different intenvetion approaches on the abilities of tone recognition by hearing-impaired children

Objective To study the influence of different auditory intervention approaches on the abilites of tone recognition by hearing-impaird children. Methods 84 cases were divided into three groups: cochlear implant recipients' group,hearing aid group and the normal hearing as control group. The tone recognition for monosyllabic words and spondaic words were measured. Results The tone recognition result for cochlear implant group with monosyllabic and spondaic words was significant higher than that of the hearing aid group (P<0.01),but was significantly lower than that of the normal children (P<0.01). Conclusion Cochlear implant provides significant benefit in tone recognition for children with profound hearing loss.
