摘要

目的探讨可接受噪声级(acceptable noise level,ANL)测试在普通话听障人群助听器效果评估中的应用。方法选取佩带助听器3个月3年的中度到中重度听障者37例,根据助听器使用情况将其分为全天使用助听器组、部分时间使用组和拒绝使用组;利用前期经过等价性评估的普通话可接受噪声级测试材料,对三组人群依次进行裸耳和助听下的ANL测试、日常生活助听器满意度问卷(the satisfaction with amplification in daily life,SADL)评估,分析三组ANL值和SADL得分的差异。结果①37例听障者个体自身裸耳和助听下最舒适响度级(most comfortable level,MCL)、背景噪声级(background noise level,BNL)值差异有统计学意义(P<0.05),而ANL值差异无统计学意义(P>0.05);②全天使用助听器组裸耳下ANL值明显低于部分时间和拒绝使用助听器组(P<0.05);③全天使用助听器组SADL量表得分高于部分时间使用和拒绝使用助听器组(P<0.05),后两组人群间差异无统计学意义(P>0.05);④Pearson相关分析显示:裸耳ANL值与听障者性别、年龄均无相关性(P>0.05),与气导平均听阈存在较弱相关性(r=0.460,P=0.004)。结论可接受噪声级测试可反映个体耐受噪声能力的大小,可初步利用其来预估助听器选配效果。
