目的：在中国大陆听力正常的听众中，开发和评估可接受噪声水平（ANL）测试的普通话语音信号内容。设计图：普通话ANL测试使用了三套不同的普通话运行语音材料，分别从小学，中学和高中教科书中选择。对于每一个话语，两个ANL测量，并平均为每个实验条件下使用ANL测试程序。研究样本：31名听力正常的听众参加了这项研究。结果如下：听力正常者的ANLs有显著差异，但三组测试材料的MCL和ANLs没有差异。Pearson相关分析表明，3个供试材料的MCL与ANL之间存在显著的相关性，且一级材料的MCL-ANL之间的相关性明显优于其他2个材料。结论：（1）不同的普通话跑语内容对普通话听力正常者的可接受噪声水平没有影响;（2）小学生跑语应作为普通话可接受噪声水平测试材料，用于评价助听器验配效果。
Objective : To develop and evaluate the Mandarin speech signal content on the acceptable noise level (ANL) test in listeners with normal hearing in mainland China. Design : The Mandarin ANL tests were conducted using three different sets of Mandarin running speech materials which were chosen from textbooks for primary school, secondary school, and high school, respectively. For each discourse, two ANL measurements were obtained and averaged for each experimental condition using ANL test procedures. Study Sample : Thirty-one normal-hearing listeners participated in this study. Results : There were significant differences for ANLs among the normal-hearing listeners, but no differences were found for MCLs and ANLs for the three sets of test materials. The Pearson correlations suggested significant correlations between MCL and ANL among the three test materials; also the results showed that the correlation coefficient between MCL-ANL of the primary material was much better than other two materials. Conclusions : (1) The contents of different Mandarin running speeches may not affect the acceptable noise level in Mandarin normal-hearing listeners; (2) The running speech selected from the primary school ought to be used as the Mandarin acceptable noise level test material to evaluate the outcomes of hearing aid fitting.
