摘要
目的 通过对302例药物致聋聋儿的临床观察,研究听力对语言影响的表现,从中摸索积极的矫正补偿方法,使聋儿能听会说,早日回归主流社会。方法:根据听力损失以1/2增益法,选择不同型号的助听器,用具有频率特性的玩具进行适应性训练,采用视觉强化测听法和言语测听法,调整助听器增益,努力使各频率尽可能进入言语香蕉图。结果 100%聋儿表现听觉的敏感性和言语的清晰度低,且存在不同程度的“重振”;聋儿助听补偿效果越好,语言清晰度越高;聋儿只能在信噪比>10 dB SPL的情况下才能听懂语言;言语识别中存在有不同种类的掩蔽现象;双耳配戴助听器对言语接受阈能提高约15%左右。结论:双耳配戴助听器以及利用助听器的微调和耳模的声学作用来改变助听器的频响,选择电脑编程、全数字、带有“AGC”功能、带有指向性麦克风等不同功能的助听器,都是十分有效的矫正措施;选择信噪比≥10 dB SPL的学习环境;充分利用视觉、触觉功能补偿作用;努力学习好辅音;教师正确控制语音、语速、声调、掌握抑扬顿挫,防止声音向上、向后、向前掩蔽。
Objective To investigate the effects of audition on speech test and the methods ofremedy for hearing-impaired children based on the clinical observation on 302 hearing-impaired children ofototoxic causes. Method To choose different types of hearing aids, fitting with the half gain rule. Provideadaptive training using toys with appropriate frequency characteristic. VRA were conducted to obtain allinformation to ensure amplification is most appropriate. This paper offers a detailed study of how thesubjects are fitted with hearing aids and the effects of amplification are evaluated.'
