目的 对普通话噪声接受度追踪(tracking of noise tolerance,TNT)测试材料进行复测信度评估,并比较测试结果的平均可容忍噪声水平(average tolerable noise level,aTNL)与程序估算的TNL值(estimated tolera-ble noise level,eTNL)是否存在差异.方法 对25例听力言语正常的成年受试者在测试当天先后进行两次普通话版TNT测试[分别为测试一(C1),测试二(C2)],13例于1周后进行复测[测试三(C3),言语材料主题同C2],三次测试的刺激声条件均为言语声0°,连续语谱噪声180°.通过比较C1与C2、C2与C3的TNT分数和aTNL值的相关性来分别评估普通话版TNT测试材料期内、期间测试的复测信度.结果 25例受试者C1、C2的aTNL值分别为83.42±3.09、83.50±3.18 dB SPL,eTNL 值分别为84.08±3.53、83.95±3.85 dB SPL;13 例受试者 C3 的 aT-NL值和eTNL值分别为83.16±2.13、83.18±2.64 dB SPL.期内比较(C1与C2)、期间比较(C2与C3)的TNT分数差值的95％CI分别为2.36、2.75 dB,Pearson相关性分析显示期内(r=0.837,P＜0.001)、期间(r=0.867,P＜0.001)的复测信度良好.除C1的aTNL与eTNL存在统计学差异(P＜0.05)之外,其余TNT测试的aTNL与eTNL均无统计学差异(均P＞0.05),且90％以上的受试者可在1分钟内获得eTNL.结论 普通话版TNT测试的复测信度良好,具有高可靠性、高效性.
Objective To evaluate the Mandarin tracking of noise tolerance(TNT)test material and compare the differences between the average tolerable noise level(aTNL)value obtained from assessment and the program-estimated tolerable noise level(eTNL).Methods A total of 25 subjects with normal hearing and aural communica-tional ability were selected to undergo two of the mandarin TNT tests successively(respectively test 1,C1;test 2,C2),and 13 of them completed the third test(C3)under the same test condition as test 2 at least 1 week later.The stimulus for the three test conditions was presented with"speech 0°,continuous noise 180°".Results The aTNL of 25 participants for C1 and C2 was 83.42±3.09 dB SPL and 83.50±3.18 dB SPL,respectively.The eTNL of 25 participants for C1 and C2 were 84.08±3.53 dB SPL and 83.95±3.85 dB SPL,respectively.The aTNL and eT-NL for 13 subjects who participated in C3 was 83.16±2.13 dB SPL and 83.18±2.64 dB SPL,respectively.The intra-session(C1 vs C2)and inter-session(C2 vs C3)test-retest reliability were 2.36 dB and 2.75 dB,respectively.Pearson correlation analysis showed that intra-session(r=0.837,P＜0.001)and inter-session(r=0.867,P＜0.001)test-retest reliability was good.There was no statistical difference between aTNL and eTNL in the other TNT tests(P＞0.05 for both)except that aTNL and eTNL were statistically different in C1(P＜0.01),and more than 90％of the subjects could obtain eTNL within 1 minute.Conclusion The test-retest reliability of Mandarin tracking of noise tolerance test is good,with advantages of high reliability and efficiency.
