摘要
目的:通过对普通话可接受噪声级(M-ANL)材料进行复测信度评估,分析正常人的ANL与对噪声耐受的关系。方法:选取听力言语正常的21～28岁青年受试者30例,对其进行M-ANL测试,再分别于1周及2周后,以同样的测试条件进行第2次复测。每位受试者于第1次测试前填写1份对噪声耐受问卷。使用SPSS17.0软件对结果进行统计学分析。结果:3次ANL值分别为(8.1±2.9)dB S/N、(7.4±2.2)dB S/N、(7.6±2.5)dB S/N,两两配对t检验及Pearson相关分析,P=0.079、0.147、0.588,r=0.722、0.746、0.849。ANL与问卷中7个问题得分均r<0.3。结论:M-ANL测试具有较好的复测信度;个体对噪声的耐受与ANL无关,其并不能正确地自我判断实际对噪声的接受能力。
Objective：To evaluate test-retest reliability of Mandarin acceptable noise level（M-ANL） test materials.Method：M-ANL was evaluated during three test sessions approximately one week apart,by testing 30 Mandarin-speaking people aged from 21 to 28 with normal aural/oral communicational abilities.The participants completed the preference for background noise questionnaire before the first session.Analysis of the test-retest results were administered by SPSS 17.0（Statistically Package for the Social Sciences Software Version 17.0）.Result：ANLs in the three sessions were（8.1±2.9）,（7.4±2.2）,（7.6±2.5）dB S/N,respectively.The correlation coefficients were 0.722,0.746 and 0.849 between two of the three sessions.The correlation coefficients of the ANL and 7 questions of the questionnaire were below 0.3.Conclusion：M-ANL test materials are found to have good test-retest reliability.Listeners’ preference for background noise is not related to their acceptance of background noise.Listeners cannot accurately assess their ability to accept background noise.
