摘　　要：目的了解广西省南宁市、柳州市及桂林市3所聋哑学校尚存残余听力聋儿的比例、残余听力的程度以及年龄的分布、原因和影响因素。方法采用DL-RB便携式听力计.对南宁市、柳州市及桂林市盲聋哑学校聋儿进行听力调查,在本底噪声≤40 dB(A)的安静房间内测听,对0.5、1、2、4 kHz 4个频率进行纯音听阈测试,取4个频率阈值的平均值作为其听力损失程度并定残。结果三所学校聋儿410例,其中男248例,女162例,年龄2～27岁,主要集中于13～18岁。接受听力测试357例,听力残疾等级分布:1级232例(65.0%),2级64例(18.0%),3级48例(13.5%),4级10例(2.6%)。不定残者3例(0.9%)。结论3所学校学生中听力残疾为3级、4级及不定残的轻、中度听力损失者61例(17.1%),说明有较多本可以通过早期干预获得听力、言语能力的聋儿错失了进入正常社会的机会,提示对聋儿进行早期诊断,早期干预的重要性。OBJECTIVE To investigate the hearing level of deafmute children in three deafmute schools in Nanning, Liuzhou and Guilin cities and reveal the.importance of early diagnosis and intervention. METHODS The pure tone hearing thresholds of 0.5, 1, 2, 4 kHz of 357 deafmute children in three deafmute schools were recorded.The disability grade was evaluated according to the average threshold of 4 frequencies. RESULTS A total of 410 students were in the three deafmute schools. There were 248 male and 162 female with an age ranged from 2 to 27 years （14.5 years）. The number of hearing disability grade from ] to IV were 232（65 %）, 64（18.0 %） , 48（13.5 %） and 10（2.6 %） respectively, and 3 children （0.9 %） could not graded the hearing disability. Sixty one children （17.0 %） with light or moderate hearing loss missed their optimal opportunity of hearing and speech rehabilitation. CONCLUSION The results reveal the importance of early diagnosis and intervention of hearing loss.
