中文摘要：

目的通过对解放军总医院研制的12张普通话儿童语句测听词表的难度等价性研究，判断该套材料是否符合言语测听材料的标准，以期挑选出具有难度一致性的词表应用于临床。方法选取36名听力正常青年受试者，采用听说复述的方式，进行12组句表的测试（每组旬表有50个关键词），以关键词计分，然后对各表得分进行统计学分析。结果进行双因素（表号和强度）方差分析和Post--Hoc两两比较，12张测试表无统计学差异。结论12张语句识别表具有较好的难度等价性，可应用于临床测试和实验研究。

英文摘要：

Objective To study the equivalence of 12 sts in quiet and to validate the lists in accordance with Mandarin BKB sentence recognition standards of speech audiometry for clinical application. Methods Thirty-six young people with normal hearing were tested at three intensities （＋4 dB,＋1 dB and -2 dB）with the 12 lists （10 sentences,50 key words in each list） through listening and repetition. The scores were calculated by the percentage of key words repeated correctly. Results Two-way （List ＆ Intensity） repeated measurement analysis of variance and Post-Hoc Tukey HSD test revealed no significant difference among the 12 lists. Conclusion The 12 Mandarin BKB sentence lists can be used in clinical assessment and experimental research.
