| 摘 要： | 真耳介入增益法是助听器常用的验配方法之一。本文应用 NAL -R、2 / 3增益公式 ,对感音神经性耳聋听力损失程度为严重聋和极度聋的聋儿 ( 1 5人 3 0只耳 ) ,进行了助听器验配 ,并对不同频率上的目标增益值、真耳介入增益值方面进行了比较 ,探索适合于这类患者的最佳预选公式。结果发现助听效果最好的是 2 / 3增益公式 ,助听效果最差的是 NAL-R公式 ,但在应用时要强调个体化。

| Abstract: | The real ear insertion gain measrement is one of methods in hearing aids fitting.Two pre selection formula (NAL R,two thirds) of prescriptive strategy had been applied to children (15 subjects,30 ears) with severe and profound sensori neural hearing loss,meanwhile,the comparison had been made at several frequencies in two aspects such as target gain and real ear insertion gain.The result indicated the more effective formula seemed to be two thirds,and NAL R formula appeared to be less effective on hearing compensation in our study.Yet individulization must be emphasized and the type of the audiogram should be taken into consideration.
