摘　　要：目的研究老年性聋患者助听前后的纯音听阈、安静及噪声下言语识别能力与国际助听器效果评估量表(the international outcome inventory for hearing aids,IOI-HA)得分的相关性。方法对20例老年性聋患者助听前和佩戴并适应助听器6个月后分别进行纯音听阈测试、安静环境下言语识别率测试及信噪比为10dB的噪声下言语识别率测试,并于助听后6个月进行IOI-HA评分,助听前的言语识别率测试采用普通话言语测听词表中的单音节词汇表,助听后的言语识别测试采用噪声下汉语普通话测试材料语句表,将助听前后纯音听阈及言语识别率的测试结果与IOI-HA得分进行多元线性回归分析。结果 20例老年性聋患者助听后平均听阈为38.1±2.4dB HL,较助听前(61.7±3.1dB HL)明显改善(P<0.05);助听前单音节词言语识别率为66.2%±5.2%,助听后安静时和噪声下语句识别率分别为85.9%±3.5%、69.2%±6.0%,IOI-HA总得分平均为25.30±4.77分。助听前后平均听阈与IOI-HA总得分均呈负相关,助听前后安静时言语识别率、助听后噪声下言语识别率与IOI-HA总得分均呈正相关,最终助听后噪声下语句识别率进入多元回归模型(P<0.001),噪声下语句识别率越高,助听器使用效果越好。结论老年性聋患者噪声下言语识别能力越好则助听效果越好;助听后模拟日常生活环境噪声下语句识别率测试有助于预估患者助听器使用效果。Objective To investigate the relationship between pure-tone audiometry（PTA）,speech discrimination abilities in quiet or in noise and the international outcome inventory for hearing aids（IOI-HA）in presbycusis patients.Methods Twenty presbycusis subjects were tested in this study.Pure-tone audiometry（PTA）and speech discrimination threshold were obtained before being fitted with hearing aids.They weared hearig aids more than six months,and pure-tone audiometry,speech discrimination scores in quite（the level= 65 dB SPL）and in noise（signal to noise ratio=10dB）were carried out in sound field.A stepwise forward multiple-regression analysis was performed to investigate the impact of PTA and speech discrimination scores to IOI-HA.Results The PTAs before or after hearing aid fittings showed a negative association with IOI-HA,while speech discrimination scores in quiet or in noise before or after hearing aid fittings showed a positive association with IOI-HA.Speech discrimination threshold in noise was identified as a single predictor of IOI-HA（P0.001）.Conclusion The relationbetween speech discrimination scores in noise and IOI-HA suggests that a poor score might limit the hearing aids outcome.The speech discrimination scores in noise help the clinicians predict the outcomes of hearing aid in realities.
