普通话噪声下言语测试在方言人群中的应用

The use of mandarin hearing in noise test in non-mandarin speakers

目的:使用普通话版噪声下言语测试材料(mandarinhearinginnoisetest,MHINT),得到听力正常不同方言人群的MHINT测试结果。方法:选择听力正常、母语非普通话受试者82名完成MHINT测试。结果进行统计学分析,并与母语普通话结果进行比较。结果:得到母语非普通话82名受试者的328个结果。母语非普通话受试者和母语普通话受试者之间在安静环境,噪声方位0°、90°、270°的测试结果均差异有统计学意义(均P<0.01);母语非普通话高学历受试者与母语非普通话低学历受试者之间结果差异有统计学意义(P<0.01)。母语非普通话受试者按年龄、讲普通话时间等因素之间测试结果差异无统计学意义(P>0.05)。结论:母语非普通话人群进行MHINT测试,与母语普通话人群相比需要更高的言语信号声和信噪比。影响MHINT测试结果的因素有受试者母语是否为普通话以及受试者的文化水平。
