摘　　要：目的:对难度等价性一致的普通话言语测听材料(MSTMs)中的单音节词表和句表进行分析,以期描绘出基于此测试材料的听力正常人识别-强度函数曲线。方法:选取18～25岁具有大专以上学历、且日常生活中以普通话作为交流方式的40例听力正常人作为受试者,对其中8例受试者进行预试验,从而获得正式测试时所需的给声强度;对其余32例受试者进行正式的言语识别测试。采用MSTMs中经过等价性评估的7张(每张50词)单音节词表和15张句表(每表50个关键词)作为测试材料。使用SPSS11.0软件对数据进行分析。结果:MSTMs单音节词表的言语识别率与给声强度间的函数关系的线性部分为Y=3.194X-46.147,识别率为50%时的给声强度为30.1dBSPL;MSTMs句表的言语识别率与给声强度间的函数关系的线性部分为Y=7.419X-121.744,识别率为50%时的给声强度为23.1dBSPL。结论:本研究初步建立了基于具有难度等价性的7张普通话单音节测听词汇表和15张普通话语句测听词汇表的正常人识别-强度函数曲线,为临床应用提供了基于MST-Ms的正常听力者的鉴别标准。Objective： To analyze the monosyllabic and sentence lists of Mandarin speech test materials （MSTMs） which have been evaluated the equivalence of difficulty, and to establish the performance-intensity function （P-I function） for people with normal hearing. Method： Forty subjects （the age-ranged from 18 to 25 years old） who speak Mandarin well in their daily lives with normal hearing participated in this study. Eight of them joined the pilot study, which aimed to identify an appropriate presentation level for the formal test. Thirty-two subjects participated in the formal speech perception test. The results were analyzed by Statistical Package for the Social Sciences （SPSS） software version 11.0. Seven monosyllabic lists （50 words per list） and 15 sentence lists （50 key words per list） were used. Result：The results showed P-I function of 3.1% per dB for monosyllabic Mandarin materials and 7.4 % per dB for sentence Mandarin materials. The sound pressure level of speech corresponding to a 50% recognition score for monosyllabic lists was 30. 1 dBSPL or 10. 1 dBHL, and 23. 1 dBSPL or 3.1 dBHL for sentence lists. Conclusion：The study established the P-I function of the Mandarin monosyllabic and sentence materials with equal difficulty, which provides the normative data for identifying the normal hearing in a clinical setting.
