摘　　要：目的：对难度等价性一致的一组双音节普通话言语测听词汇表（MSTM）的有效性进行分析，以期制定出基于此测试材料的听力正常人识别-强度函数曲线。方法：选取年龄为18-25岁具有大专以上学历，且以普通话作为日常交流方式的听力正常人35例，对5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30例受试者进行正式的言语识别测试。采用9张（每张50词）双音节词汇表作为测试材料。使用SPSS11．0软件对结果进行分析。结果：双音节MSTM的言语识别率与给声强度间的函数关系为Y=-200．9＋13．4x-0．14x^2，在26．4dBSPL给声强度处可获得50％的正确率。结论：该研究初步建立了基于9张具有难度等价性的双音节MSTM的听力正常人识别-强度函数曲线，为临床应用提供了正常听力的鉴别标准。Objective.. To analyze the reliability of disyllabic Mandarin speech test materials （MSTM） which had previously been evaluated the equivalence of difficulty, and to establish the performance-intensity function（P-I function） for people with normal hearing. Method：Thirty-five subjects （the age-range 18-25 years） with normal hearing who speak Mandarin well in their daily lives were enrolled in this study. Five of them participated the pilot study, which aimed to identify a presentation level for the formal test. The other thirty subjects participated in the formal speech perception test. The results were analyzed statistically using SPSS 11.0 software. Nine lists of the Mandarin disyllabic materials with equal difficulty were utilized. Result：P-I function was y = -200. 9＋ 13.4 x - 0.14 x^2. The sound pressure level of speech corresponding to a 50% recognition score was 26. 4 dB SPL, or 6.4 dB HL. Conclusion： This study has established the P-I function of the Mandarin disyllabic materials with equal difficulty, which provides the normative data for identifying the normal hearing in a clinical setting.
