摘　　要：目的探讨老年性聋临床听力表现特点。方法选用41例老年性聋患者进行纯音测听检查和言语测听检查(言语识别阈,言语识别率和合成语句检查)。结果纯音听力图以高频缓降和高频陡降为主。静态下言语识别率和合成语句检查得分均高于噪声下言语识别率和竞争声合成语句检查,差异有显著性意义(P<0.01)。老年性聋纯音听力损害程度与言语识别率不完全一致。结论老年性聋患者不仅有耳蜗、听神经受损和退变,更有中枢分辨能力的蜕化。)Purpose To explore the clinical audiological features in preshycusis. Methods The audition of forty one cases with presbycusis was examined with pure-tone audiometry and speech audiometry（SRT, SRS and SIS）. Results The audiograms showed a flat or steep downsloping at high frequencies in most of the cases. There were significant differences in speech recognition score and synthetic sentences identification test between in quiet and noise environmeat. The severity of hearing loss in audiogram was not consistent with the resnlts of speech recognition score. Conclusion Speech andiometry combined with pure-tone audiometry is helpful in determining the degree and type of hearing loss. Not only the peripheral but also the central auditory system are involved in presbycusis.
