摘要
120例聋哑儿240耳的脑干电反应测听结果234耳(97.5%)有残余听力,216耳(88.3%)听阈高于110dB,平均听阈为83.7dB,在100dB 可诱出波Ⅰ、Ⅲ、Ⅴ者共180耳,达75%,波形变异及波Ⅴ波幅低于0.15μⅤ者占18%;因此大部分聋哑儿具备语言训练的条件。
BER results of 240 ears from 120 cases of deaf-mute children revealedthat 234 ears(97.5%)had residual hearing.The threshold of 216 ears(88.3%)were decreased to 110 dB.The average threshold was 83.7dB.Waves Ⅰ Ⅱ and Ⅴ might be induced at 100dB in 180 ears(75%).Wavevariform and the amplitude of wave Ⅴ decreased to 0.15μV account for18% of the total ears.Therefore,the most part of deaf-mute childrenhave got the prerequisites of speech-training.
